Abstract
Albizia adianthifolia (Schumach.) (Fabaceae) is a medicinal herb used for the treatment of epilepsy and memory impairment. This study aims to investigate the anticonvulsant effects of Albizia adianthifolia aqueous extract against pentylenetetrazole (PTZ)-induced spontaneous convulsions in mice; and determine whether the extract could mitigate memory impairment, oxidative/nitrergic stress, GABA depletion and neuroinflammation. Ultra-high performance liquid chromatography/mass spectrometry analysis was done to identify active compounds from the extract. Mice were injected with PTZ once every 48 h until kindling was developed. Animals received distilled water for the normal group and negative control groups, doses of extract (40, 80, or 160 mg/kg) for the test groups and sodium valproate (300 mg/kg) for the positive control group. Memory was measured using Y maze, novel object recognition (NOR) and open field paradigms, while the oxidative/nitrosative stresses (MDA, GSH, CAT, SOD and NO), GABAergic transmission (GABA, GABA-T and GAD) and neuro-inflammation (TNF-α, IFN-γ, IL- 1β, and IL-6) were determined. Brain photomicrograph was also studied. Apigenin, murrayanine and safranal were identified in the extract. The extract (80-160 mg/kg) significantly protected mice against seizures and mortality induced by PTZ. The extract significantly increased the spontaneous alternation and the discrimination index in the Y maze and NOR tests, respectively. PTZ kindling induced oxidative/nitrosative stress, GABA depletion, neuroinflammation and neuronal cells death was strongly reversed by the extract. The results suggest that the anticonvulsant activity of Albizia adianthifolia extract is accompanied by its anti-amnesic property, and may be supported by the amelioration of oxidative stress, GABAergic transmission and neuroinflammation.

Abstract
In our ongoing research program on the proapoptotic function of saponins, two previously undescribed saponins, named zygiaosides E (1: ) and F (2: ), were isolated from the leaves of Albizia zygia. Their structures were established based on extensive analysis of 1D and 2D NMR data, HR-ESI-MS analysis, and by chemical degradation. The proapoptotic effect of zygiaoside E (1: ) was evaluated on human malignant melanoma (A375), human epidermoid cancer (A431), and normal Homo sapiens skin tissue (TE 353.SK.) cell lines by cytometric analysis. Zygiaoside E (1: ) induced apoptosis of the two human cancer cell lines (A375 and A431) in a dose-dependent manner at 1 µM but did not induce apoptosis in noncancerous skin cells (TE 353.Sk), even when treated with concentrations up to 15 µM. The underlying mechanism of the apoptosis induction activity of zygiaoside E (1: ) on the mitochondrial membrane potential status in A375 cells was further assessed by monitoring the uptake rate of DiOC6, a mitochondrial specific and voltage-dependent fluorescent dye. The number of malignant melanoma cells emitting high fluorescence levels was decreased when cells were treated with 3 or 5 µM of zygiaoside E (1: ) during either 12 or 24 h, thereby revealing a drop of mitochondrial membrane potential in A375 cells upon treatment, which indicated mitochondrial perturbation.

Abstract
Albizia myriophylla has been used in Thai folk medicine for treating inflammation-related diseases. The wood of this medicinal plant is traditionally used as a single herbal drug in the form of an aqueous decoction and as a component in several Thai herbal formulations for the remedy of fever, sore throat, and aphthous ulcers. This study aimed to evaluate in vivo the anti-inflammatory potential and possible mechanism of action of the standardized wood extract of A. myriophylla as well as to investigate the anti-inflammatory activity and physicochemical properties of the developed herbal gel formulation containing standardized wood extract of A. myriophylla. Results of quantitative HPLC analysis demonstrated that the standardized wood extract of A. myriophylla contained 22.95 mg/g of 8-methoxy-7,3',4'-trihydroxyflavone, a bioactive marker compound of A. myriophylla. The standardized wood extract of A. myriophylla (1% w/v) exhibited remarkable inhibition (54.4 - 80.3%) in the croton oil model of topical inflammation at all assessment times, comparable to standard indomethacin (55.3 - 63.6%). Real-time quantitative reverse transcription-polymerase chain reaction was performed to clarify the anti-inflammatory mechanism of standardized wood extract of A. myriophylla, and the result showed that this standardized extract decreased lipopolysaccharide-induced nitric oxide synthase mRNA levels in a dose-dependent manner. The developed herbal gel containing standardized wood extract of A. myriophylla (1% w/w) had good physicochemical characteristics and exhibited potent inhibition (51.4 - 77.8%) of inflammation in a rat ear edema model at all assessment times, comparable to indomethacin gel (33.3 - 40.5%). The notable anti-inflammatory activity of standardized wood extract of A. myriophylla and its developed herbal gel formulation indicates their potential application as natural anti-inflammatory agents.

Abstract
The global population is increasing day by day. To meet the food demand for such a huge number of people, crop production must increase without damaging the environment, and to prevent synthetic chemical herbicides from polluting the environment, controlling weeds using bioherbicides is essential. Accordingly, using phytotoxic substances obtained from plants for biological weed management has attracted attention. The plant Albizia richardiana possesses phytotoxic compounds that have been previously recorded. Hence, we have conducted this research to characterize more phytotoxic compounds in Albizia richardiana. Aqueous methanolic extracts of Albizia richardiana plant significantly restricted the growth of the examined plants lettuce and Italian ryegrass in a species- and concentration-dependent manner. Three active phytotoxic compounds were isolated through various chromatographic methods and identified as compound 1, 2, and 3. Compound 3 exhibited stronger phytotoxic potentials than the other two compounds and significantly suppressed the growth of Lepidium sativum (cress). The concentration of the compounds required for 50% growth reduction (I50 value) of the Lepidium sativum seedlings ranged between 0.0827 to 0.4133 mg/mL. The results suggest that these three phytotoxic compounds might contribute to the allelopathic potential of Albizia richardiana.

Abstract
Nano-based particles synthesized via green routes have a particular structure that is useful in biomedical applications as they provide cheap, eco-friendly, and non-toxic nanoparticles. In the present study, we reported the effect of various concentrations of Zinc oxide nanoparticles synthesized using A. lebbeck stem bark extract (ZnO NPsAL) as stabilizing agent on rat biochemical profiles and tissue morphology. Adult Wistar rats weighing 170 ± 5 g were randomly classified into eight groups of five rats each; Group A served as a control fed with normal diet and water. Groups B1, B2, C1, C2, D1, D2, and E were treated with 40 mg/kg and 80 mg/kg of the 0.01, 0.05, and 0.1 M biosynthesized ZnO NPsAL and zinc nitrate daily by the gavage method, respectively. The rats were anesthetized 24 h after the last treatment, blood samples, kidney, heart, and liver tissues were collected for biochemical and histopathological analysis. The rats mean body weight, serum alkaline phosphatase, alanine aminotransferase, creatinine, urea, bilirubin, protein, albumin, globulin, total cholesterol, triacylglycerol, and high-density lipoprotein were significantly altered with an increased concentration of biosynthesized ZnO NPsAL when compared with the control group (p < 0.05; n ≥ 5). Furthermore, histopathological analysis of treated rats' kidney, heart, and liver tissue revealed vascular congestion, tubular necrosis, inflammation, and cytoplasmic vacuolation. Biosynthesized ZnO NPsAL showed significant alteration in biochemical parameters and tissue morphology in rats with increasing concentrations of the nanoparticles.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The genus Albizia (Leguminosae) comprises about 150 species and some species have been used for the treatment of rheumatism, stomachache, cough, diarrhea, and wounds in traditional and local medicine. The aim of the review: This review article documents and critically assesses the current status of the traditional uses, phytochemistry, pharmacology, and toxicology of the Albizia species. MATERIALS AND METHODS All provided literatures on the Albizia species were searched using the electronic databases (e.g. Web of Science, Elsevier, Springer, PubMed, ACS, CNKI, Google Scholar, and Baidu Scholar), books, and theses with keywords of 'Albizia' and 'Albizzia'. RESULTS Albizia species have been used for melancholia, insomnia, wounds, fever, abscesses, diabetes, headache, stomachache, diarrhea, cough, rheumatism, snake bite, malaria, and parasitic infection in traditional and local medicine. These plants mainly contain triterpenoid saponins, flavonoids, lignanoids, alkaloids, phenolic glycosides, etc. Albizia species have been demonstrated to possess various pharmacological activities. Among them, the antidiabetic, anti-inflammatory, antifertility, antianxiety, antidepressant, and anti-fever properties are consistent with the traditional and local applications of the Albizia species. CONCLUSIONS The traditional and local uses of Albizia species have been partially demonstrated by the pharmacological investigation. However, some traditional applications have not been assessed scientifically due to incomplete methodologies and ambiguous findings. Moreover, no clinical evidences support the health benefits of these plants. The systematic and comprehensive preclinical studies and clinical trials are still required to verify the pharmacological activities, clinical efficacy, and safety of Albizia species.

Abstract
A dibenzylbutane-type lignan (16), along with eight furofuran-type (1–8), five furan-type (9–13), two dibenzylbutane-type (14 and 15), two bibenztetrahydronaphthalene-type lignans (17 and 18), two neolignans (19 and 20), and six phenolic derivatives (21–26) were isolated from an MeOH extract of the stem bark of Albizia julibrissin Durazz. The chemical structures of the obtained compounds were elucidated by nuclear magnetic resonance (NMR) and mass spectrometry (MS) analyses. Of the evaluated compounds, 14 were isolated from A. julibrissin and the Fabaceae family for the first time. Anti-inflammatory effects of the isolated analogs were investigated in terms of the inhibition of the nitric oxide (NO) production in lipopolysaccharide (LPS)-stimulated murine RAW264.7 macrophage cells. Ten compounds (10–12, 14, and 17–22) displayed significant dose-dependent inhibitory effects against the NO production, with IC50 values ranging from 5.4 to 19.2 µM. Moreover, eight compounds (1–4, 9, 13, 15, and 16) exhibited moderate inhibitory activities, with IC50 values ranging from 21.0 to 62.5 µM.

Abstract
Silver nanoparticles were synthesized by using the white flower extract of Albizia lebbeck as a source of reducing and capping agents. A. lebbeck white flower extract and silver nanoparticles were checked for their antibacterial activity against Staphylococcus aureus, Escherichia coli, Pseudomonas aeroginosa and Ba cillus subtilis by using Mueller Hinton agar, nutrient agar and Luria Bertani agar using the well diffusion method. The synthesized silver nanoparticles did not show antibacterial activity at lower (0.1-0.4 mg ml-1) or higher (0.5-2.5 mg ml-1) concentrations against any of the four organisms on either of the media, even though silver nanoparticles have been well known to show antibacterial activity even at lower concentrations. The non-antibacterial properties of the synthesized silver nanoparticles against all four bacteria were confirmed using viability counting. With this unique non-antibacterial property of biogenous silver nanoparticles observed in this study, it can be stated that case by case evaluation of every synthesized silver nanoparticle needs to be done as there are multiple factors influencing their properties. Anticancer activity of these nanoparticles at different concentrations against A549 cancer cells did not show any significant decrease in cell viability highlighting its biocompatible nature. Thus, these silver nanoparticles can be a best suited candidate for drug delivery.

Abstract
Five oleanane-type triterpene glycosides including three new ones, proceraosides E-G (1-3), were isolated from a MeOH-soluble extract of Albizia procera bark. The structures of 1-3 were determined by use of NMR spectra, HRESIMS, and chemical methods. Compounds 1-5 exhibited inhibitory activities against the proliferation of the A549, SKBR3, AZ521, and HL60 human cancer cell lines (IC50 0.28-1.8 μM). Additionally, the apoptosis-inducing activity of compound 2 was evaluated by Hoechst 33342 staining and flow cytometry, while the effects of 2 on the activation of caspases-9, -8, and -3 in HL60 cells were revealed by Western blot analysis.

Abstract
Smart polymers, one of the class of polymers with extensive growth in the last few decades due to their wide applications in drug targeting and controlled delivery systems. With this in mind, the aim of the present study is to design and formulate smart releasing o/w emulsion by using Albizia lebbeck L. seed polysaccharide (ALPS). For this purpose, the physicochemical and drug release characteristics like emulsion capacity (EC), emulsion stability (ES), viscosity, microscopy, zeta potential, polydispersity index (PDI) and in-vitro drug release were performed. The EC and ES values were found to increase with an increased concentration of ALPS. The emulsion formulations were statistically designed by using 32 full factorial design. All the emulsions showed a shear-thinning behavior. The zeta potential and polydispersity index were found to be in the range of -35.83 mV to -19.00 mV and 0.232-1.000 respectively. Further, the percent cumulative drug release of the emulsions at 8 h was found to be in the range of 30.19-82.65%. The drug release profile exhibited zero order release kinetics. In conclusion, the ALPS can be used as a natural emulsifier and smart polymer for the preparation of pH sensitive emulsions in drug delivery systems.

Abstract
CONTEXT The leaves of Albizia zygia (DC.) J.F. Macbr. (Leguminosae-Mimosoideae) are used in Ghanaian traditional medicine for the treatment of pain, inflammatory disorders and fever (including malaria). OBJECTIVES The present study evaluated the anti-inflammatory, antipyretic and analgesic effects of the hydroethanol leaf extract of Albizia zygia (AZE) in animal models. MATERIALS AND METHODS The anti-inflammatory and antipyretic effects of AZE were examined in the carrageenan-induced foot oedema model and the baker's yeast-induced pyrexia test respectively. The analgesic effect and possible mechanisms of action were also assessed in the formalin test. RESULTS AZE (30-300 mg/kg, p.o.), either preemptively or curatively, significantly inhibited carrageenan-induced foot edema in 7-day-old chicks (ED50 values; preemptive: 232.9 ± 53.33 mg/kg; curative: 539.2 ± 138.28 mg/kg). Similarly, the NSAID diclofenac (10-100 mg/kg, i.p.) significantly reduced the oedema in both preemptive (ED50: 21.16 ± 4.07 mg/kg) and curative (ED50: 44.28 ± 5.75 mg/kg) treatments. The extract (30-300 mg/kg, p.o.) as well as paracetamol (150 mg/kg, p.o.) also showed significant antipyretic activity in the baker's yeast-induced pyrexia test (ED50 of AZE: 282.5 ± 96.55 mg/kg). AZE and morphine (1-10 mg/kg, i.p.; positive control), exhibited significant analgesic activity in the formalin test. The analgesic effect was partly or wholly reversed by the systemic administration of naloxone, theophylline and atropine. CONCLUSION The results suggest that AZE possesses anti-inflammatory, antipyretic and analgesic properties, which justifies its traditional use. Also, the results show the involvement of the opioidergic, adenosinergic and the muscarinic cholinergic pathways in the analgesic effects of AZE.

Abstract
CONTEXT Albizia odoratissima (L. f.) Benth has been used in Indian folk medicine to treat numerous inflammatory pathologies, such as leprosy, ulcers, burns and asthma. OBJECTIVE To evaluate the antioxidant and antimicrobial properties of A. odoratissima. MATERIALS AND METHODS Dried leaves of A. odoratissima were extracted in organic solvents (hexane, chloroform, ethyl acetate, and methanol). The total phenolic content (TPC) and total flavonoid content (TFC) were determined using the Folin-Ciocalteu and aluminum chloride colorimetric methods, respectively. The antioxidant activity was examined using 2,2-diphenyl-1-picrylhydrazyl (DPPH), hydrogen peroxide (H2O2), 2,2'-azino-bis-(3-ethylbenzothiazoline-6-sulphonic acid) diammonium salt (ABTS), and ferric reducing antioxidant power (FRAP) assays. The antibacterial activity was examined using minimum inhibitory concentration (MIC) and the minimum bacterial concentration (MBC), determined by broth microdilution method against Gram-negative bacteria (Klebsiella pneumoniae, Escherichia coli, Pseudomonas aeruginosa, and Proteus vulgaris) and Gram-positive bacterium (Staphylococcus aureus). RESULTS The TPC ranged from 4.40 ± 1.06 to 1166.66 ± 31.85 mg GAE/g of dry weight (DW), and the TFC ranged from 48.35 ± 3.62 to 109.74 ± 1.84 mg QE/g of DW. The IC50 values of the ethyl acetate extract for DPPH, ABTS, and H2O2 were 10.96 ± 0.40, 4.35 ± 0.07, and 163.82 ± 1.52 μg/mL, respectively. Both methanol and ethyl acetate extracts demonstrated effective antibacterial activity with MICs and MBCs values ranging 136-546 μg/mL and 273-1093 μg/mL, respectively, against the tested pathogenic species. CONCLUSIONS The leaves of A. odoratissima showed potent free radical scavenging property and antimicrobial activity.

Abstract
Albizia harveyi is a tropical deciduous tree, found across South and Eastern Africa and widely used in traditional medicine. The leaf extract ameliorated the damaging effects of the frozen-thawing process in cryopreserved bull semen. In a dose-dependent pattern, sperm motility, viability, and membrane integrity were improved compared to the untreated control. Furthermore, the extract increased the percentage of viable sperm cells and reduced the percentages of early apoptotic and apoptotic sperm cells as well as the damage in sperm ultra-structure. These activities are in agreement with the robust antioxidant properties in vitro and in the seminal fluid as observed in the total antioxidant capacity and the lipid peroxidation parameter malondialdehyde. LC-MS yielded 35 compounds. The extract was dominated by quercetin-O-galloyl-hexoside and quercetin-O-pentoside, along with other flavonoid glycosides. The polyphenols are probably responsible for the observed activities. In conclusion, the current findings show that A. harveyi leaves are rich in bioactive polyphenols with functional properties, validating its traditional use.

Abstract
Albizzia julibrissin Durazz, a Chinese Medicine, is commonly used for its anti-anxiety effects. (−)-syringaresnol-4-O-β-d-apiofuranosyl-(1→2)-β-d-glucopyranoside (SAG) is the main ingredient of Albizzia julibrissin Durazz. The present study investigated the anxiolytic effect and potential mechanisms on the HPA axis and monoaminergic systems of SAG on acute restraint-stressed rats. The anxiolytic effect of SAG was examined through an open field test and an elevated plus maze test. The concentration of CRF, ACTH, and CORT in plasma was examined by an enzyme-linked immune sorbent assay (ELISA) kit while neurotransmitters in the cerebral cortex and hippocampus of the brain were examined by High Performance Liquid Chromatography (HPLC). We show that repeated treatment with SAG (3.6 mg/kg, p.o.) significantly increased the number and time spent on the central entries in the open-field test when compared to the vehicle/stressed group. In the elevated plus maze test, 3.6 mg/kg SAG could increase the percentage of entries into and time spent on the open arms of the elevated plus maze. In addition, the concentration of CRF, ACTH, and CORT in plasma and neurotransmitters (NE, 5-HT, DA and their metabolites 5-HIAA, DOPAC, and HVA) in the cerebral cortex and hippocampus of the brain were decreased after SAG treatment, as compared to the repeated acute restraint-stressed rats. These results suggest that SAG is a potential anti-anxiety drug candidate.

Abstract
CONTEXT Albizia species are reported to exhibit many biological activities including antiovulatory properties in female rats and antispermatogenic and antiandrogenic activities in male rats. OBJECTIVE The present study investigates the flavonoids of Albizia amara (Roxb.) B. Boivin (Fabaceae) leaves and evaluates their activity on gene expression of fertility and antioxidant glutathione-S-transferase-related genes of treated female mice in addition to their effect on DNA damage. MATERIALS AND METHODS Plant materials were extracted by using 70% methanol for 48 h, the extract was chromatographed on a polyamide 6S column, each isolated compound was purified by using Sephadex LH-20 column; its structure was elucidated by chemical and spectral methods. Both the leaves extract and myricitrin (200, 30 mg/kg bw/d, respectively) were assayed for their effect on DNA damage in female mice after four weeks treatment using Comet assay. Their modulatory activity on gene expression of fertility (aromatase CYP19 and luteinizing hormone LH) and antioxidant glutathione-S-transferase (GST)-related genes of treated female mice were investigated by real-time PCR (qPCR). RESULTS Quercetin-3-O-gentiobioside, myricitrin, quercetin-3-O-α-rhamnopyranoside, myricetin, quercetin and kaempferol were isolated and identified from the studied taxa. Myricitrin and the extract induced low rate of DNA damage (4.8% and 5%, respectively), compared with the untreated control (4.2%) and significantly down-regulated the expression of CYP19 and LH genes and up-regulated GST gene. DISCUSSION AND CONCLUSION Our results highlight the potential effect of the leaves extract of Albizia amara and myricitrin as fertility-regulating phytoconstituents with ability to protect DNA from damage and cells from oxidative stress.

Abstract
CONTEXT AND OBJECTIVE Viperid venom-induced chronic local-toxicity continues even after anti-snake venom treatment. Therefore, traditional antidote Albizia lebbeck L. (Fabaceae) seed extract was tested against Echis carinatus S. (Viperidae) venom (ECV)-induced local toxicity to evaluate its complementary remedy. MATERIALS AND METHODS Soxhlet extraction of A. lebbeck seeds was performed with the increasing polarity of solvents (n-hexane to water); the extract was screened for phytochemicals (alkaloids, anthraquinones, flavonoids, glycosides, phenolics, saponins, steroids and tannins). In preliminary in vitro analysis, A. lebbeck methanolic extract (ALME) demonstrated significant inhibition of ECV proteases, the major enzyme-toxin responsible for local- toxicity. Therefore, in vitro neutralizing potential of ALME was further evaluated against hyaluronidases and phospholipase A2 (1:1-1:100 w/w). In addition, alleviation of ECV induced characteristic local- toxicity [haemorrhage (i.d.) and myotoxicity (i.m.)] was determined in mice. RESULTS ALME contained high concentrations of phenolics and flavonoids and demonstrated significant in vitro inhibition of ECV protease (IC50 = 36.32 μg, p < 0.0001) and hyaluronidase (IC50 = 91.95 μg, p < 0.0001) at 1:100 w/w. ALME significantly neutralized ECV induced haemorrhage (ED50 = 26.37 μg, p < 0.0001) and myotoxicity by significantly reducing serum creatinine kinase (ED50 = 37.5 μg, p < 0.0001) and lactate dehydrogenase (ED50 = 31.44 μg, p = 0.0021) levels at 1:50 w/w. DISCUSSION AND CONCLUSION ALME demonstrated significant neutralization of ECV enzymes that contribute in local tissue damage and haemostatic alterations. The study scientifically supports the anecdotal use of A. lebbeck in complementary medicine and identifies ALME as principle fraction responsible for antivenom properties.

Abstract
BACKGROUND Sclerotium rolfsii Sacc. is a destructive soil-borne plant pathogen that infects over 500 plant species and causes significant yield losses in many economically important plant species. Synthetic fungicides used to combat the menace also pollute the environment and cause health hazards. In order to search environmental friendly alternatives from natural resources, methanolic extracts of three leguminous tree species namely Acacia nilotica (L.) Willd. ex Delile subsp. indica (Benth.) Brenan, Prosopis juliflora (Sw.) DC. and Albizia lebbeck (L.) Benth. were evaluated for their antifungal activity against S. rolfsii and A. nilotica subsp. indica exhibited the maximum fungicidal potential. MATERIALS AND METHODS Two hundred grams dried leaf material of each of the three test plant species were extracted with methanol for two weeks. After filtration, methanol was evaporated on a rotary evaporator. Malt extract broth was used to make various concentrations of the crude methanolic extracts and their antifungal potential was determined by comparing the fungal biomass in various treatments with control. Chemical composition of methanolic leaf extract of A. nilotica subsp. indica was determined through GC-MS analysis. RESULTS Methanolic leaf extract of A. nilotica subsp. indica showed the highest fungicidal activity. Fungal biomass was decreased by 17-55% due to various concentrations of this extract over control. Different concentrations of P. juliflora reduced fungal biomass by 3-52%. Fourteen compounds were identified in methanolic extract of A. nilotica subsp. indica. 9,12,15-octadecatrienoic acid, methyl ester, (Z,Z,Z,)- (16.59%) was the most abundant compound followed by 1-pentanol, 2 methyl-, acetate (14.80%); hexanedioic acid, dimethyl ester (13.10%) and cyclotriaconta- 1, 7, 16, 22-tetraone (10.28%). CONCLUSION This study concludes that methanolic leaf extract of A. nilotica subsp. indica can be used for management of S. rolfsii.

Abstract
The seed coat is an external tissue that participates in defense against insects. In some nonhost seeds, including Albizia lebbeck, the insect Callosobruchus maculatus dies during seed coat penetration. We investigated the toxicity of A. lebbeck seed coat proteins to C. maculatus. A chitin-binding protein fraction was isolated from seed coat, and mass spectrometry showed similarity to a C1 cysteine protease. By ELM program an N-glycosylation interaction motif was identified in this protein, and by molecular docking the potential to interact with N-acetylglucosamine (NAG) was shown. The chitin-binding protein fraction was toxic to C. maculatus and was present in larval midgut and feces but not able to hydrolyze larval gut proteins. It did not interfere, though, with the intestinal cell permeability. These results indicate that the toxicity mechanism of this seed coat fraction may be related to its binding to chitin, present in the larvae gut, disturbing nutrient absorption.

Abstract
Saponin frsom Cortex Albiziae (SCA) are extensively used in the clinical treatment of tumor and depression. However, SCA may cause several adverse effects, including reproductive toxicity. The present study was designed to assess the mechanism by which SCA cause reproductive toxicity in female mice. The general reproductive toxicity testing was accomplished in female Kunming mice. The animals were divided into four groups: three groups that were treated by oral gavage with 135, 270, and 540 mg·kg(-1)·d(-1) of SCA prepared in physiological saline, respectively, and one vehicle control group that was treated with physiological saline only. The gestational toxicity tests were conducted at 540 mg·kg(-1)·d(-1). The general reproductive toxicity results showed that the pregnancy rate of the SCA-treated group decreased with the pregnancy rate being decreased by 70% at 540 mg·kg(-1)·d(-1). SCA elicited maternal toxicity in the ovary and the uterus, but no fetal toxicity or teratogenicity was observed. The rates of implantation in the early, middle, and late pregnancy were all decreased, with stillbirths and maternal deaths being observed. Histopathological changes showed that SCA adversely affected the ovary and the uterus. In conclusion, SCA-induced reproductive toxicity in female mice is most likely caused by its damage to the ovary and the uterus.

Abstract
We have limited understanding of how tropical canopy foliage varies along environmental gradients, and how this may in turn affect forest processes and functions. Here, we analyse the relationships between canopy leaf area index (LAI) and above ground herbaceous biomass (AGBH) along environmental gradients in a moist forest and miombo woodland in Tanzania. We recorded canopy structure and herbaceous biomass in 100 permanent vegetation plots (20 m × 40 m), stratified by elevation. We quantified tree species richness, evenness, Shannon diversity and predominant height as measures of structural variability, and disturbance (tree stumps), soil nutrients and elevation as indicators of environmental variability. Moist forest and miombo woodland differed substantially with respect to nearly all variables tested. Both structural and environmental variables were found to affect LAI and AGBH, the latter being additionally dependent on LAI in moist forest but not in miombo, where other factors are limiting. Combining structural and environmental predictors yielded the most powerful models. In moist forest, they explained 76% and 25% of deviance in LAI and AGBH, respectively. In miombo woodland, they explained 82% and 45% of deviance in LAI and AGBH. In moist forest, LAI increased non-linearly with predominant height and linearly with tree richness, and decreased with soil nitrogen except under high disturbance. Miombo woodland LAI increased linearly with stem density, soil phosphorous and nitrogen, and decreased linearly with tree species evenness. AGBH in moist forest decreased with LAI at lower elevations whilst increasing slightly at higher elevations. AGBH in miombo woodland increased linearly with soil nitrogen and soil pH. Overall, moist forest plots had denser canopies and lower AGBH compared with miombo plots. Further field studies are encouraged, to disentangle the direct influence of LAI on AGBH from complex interrelationships between stand structure, environmental gradients and disturbance in African forests and woodlands.

Abstract
BACKGROUND While the Albizia adianthifolia (Schumach.) W. Wright (Fabaceae) is a traditional herb largely used in the African traditional medicine as analgesic, purgative, antiinflammatory, antioxidant, antimicrobial, memory-enhancer, anxiolytic and antidepressant drug, there are no scientific data that clarify the anxiolytic and antidepressant-like effects in 6-hydroxydopamine (6-OHDA)-lesioned animal model of Parkinson's disease. This study was undertaken in order to identify the effects of aqueous extract of A. adianthifolia leaves on 6-hydroxydopamine-induced anxiety, depression and oxidative stress in the rat amygdala. METHODS The effect of the aqueous extract of A. adianthifolia leaves (150 and 300 mg/kg, orally, daily, for 21 days) on anxiety and depression was assessed using elevated plus-maze and forced swimming tests, as animal models of anxiety and depression. Also, the antioxidant activity in the rat amygdala was assessed using assessed using superoxide dismutase, glutathione peroxidase and catalase specific activities, the total content of the reduced glutathione, protein carbonyl and malondialdehyde levels. Statistical analyses were performed using by one-way analysis of variance (ANOVA). Significant differences were determined by Tukey's post hoc test. F values for which p < 0.05 were regarded as statistically significant. Pearson's correlation coefficient and regression analysis were used in order to evaluate the connection between behavioral measures, the antioxidant defence and lipid peroxidation. RESULTS 6-OHDA-lesioned rats exhibited the following: decrease of the exploratory activity, the percentage of the time spent and the number of entries in the open arm within elevated plus-maze test and decrease of swimming time and increase of immobility time within forced swimming test. Administration of the aqueous extract significantly exhibited anxiolytic- and antidepressant-like effects and also antioxidant potential in the rat amygdala. CONCLUSIONS Our results suggest that the aqueous extract ameliorates 6-OHDA-induced anxiety and depression by attenuation of the oxidative stress in the rat amygdala. These pieces of evidence accentuate its use in traditional medicine.

Abstract
CONTEXT Albizia myriophylla Benth (Leguminosae) is a medicinal plant widely used in Thailand and other Asian countries as a folk medicine remedy for many ailments. OBJECTIVE The objective of this study is to investigate the chemical compositions, antibacterial activity, and cytotoxicity of A. myriophylla wood. MATERIALS AND METHODS The structure identification of the isolated compounds was established using spectroscopic methods. In vitro antibacterial activity against Streptococcus mutans, Staphylococcus aureus, and Bacillus cereus and the cytotoxicity against KB cells of extracts and compounds from A. myriophylla were performed using broth microdilution and resazurin microplate assays, respectively. The lupinifolin content in A. myriophylla extracts was quantified by high-performance liquid chromatography. RESULTS A rare flavan-3,4-diol (1) together with eight known compounds (2-9) were isolated from the wood of A. myriophylla. Compounds 4-9 exhibited anti-S. mutans activity, of which lupinifolin (5) was the most potent with an MIC value of 0.98 µg/mL, followed by its dihydroxy derivative 4 with an MIC value of 62.5 µg/mL. Compounds 4 and 5 also displayed marked antibacterial activity against B. cereus and S. aureus (MIC value 15.63-125 µg/mL) and showed strong cytotoxic activity against KB cells (IC50 value 4.95-12.55 µg/mL). The lupinifolin contents in ethanol extracts from two different collections of this plant originating from central and southern Thailand were 93.85 and 0.04 mg/g, respectively. CONCLUSION This is the first report of compounds 1-4 from A. myriophylla. Compounds 4 and 5 showed potent antibacterial and cytotoxic activities compared with other isolates. The anti-S. mutans activity of A. myriophylla extracts seems to be related to the lupinifolin content.

Abstract
OBJECTIVE To optimize the extraction technology of total flavonoids from Albizia julibrissin flower by combining surfactant with ultrasonic technology. METHODS Using Box-Behnken central composition design and response surface methodology, the effects of surfactant concentration, liquid-solid ratio and ultrasound time on the yield of total flavonoids were studied based on the extraction rate to determine the optimum extraction conditions of total flavonoids. RESULTS Optimum conditions for extraction of Albizia julibrissin flower were as follows: mass percentage of 2. 5% SDS,15 times of 60% ethanol,ultrasonic time of 31 min. Under these conditions,the extraction rate of total flavonoids from Albizia julibrissin flower was 0. 853%. Using this technology, the extraction yield increased by 93. 0% as compared with that using ultrasonic technology alone. CONCLUSION The optimum extraction technology can be used for extraction of total flavonoids from Albizia julibrissin flower for its simplicity and responsibility.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Albizia glaberrima is a shrub found in the deciduous forest and jungle of the coastal plain of West Africa. Preparations of the plant are used traditionally in the treatment of fever, pain and central nervous system disorders, including epilepsy. This study was conducted to investigate the neuropharmacological effects of the aqueous leaf extract of Albizia glaberrima in mice. MATERIALS AND METHODS The hole-board, elevated plus-maze, thiopentone-induced sleep (anxiolytic/sedative-hypnotic), traction, climbing, inclined screen (muscle relaxant), strychnine-, picrotoxin- and pentylenetetrazole (PTZ)-induced convulsion (anticonvulsant) tests were employed in this study. RESULTS Albizia glaberrima extract at 200mg/kg significantly increased the duration of head dips (p<0.05) and number of open arms entry (p<0.01) compared with control in the hole-board and elevated plus-maze tests, respectively. At 400mg/kg, Albizia glaberrima extract significantly reduced the number of sectional crossings relative to control. The extract at 400mg/kg significantly (p<0.05) increased the duration of sleep compared with control in the thiopentone-induced hypnosis test. Albizia glaberrima extract at 200mg/kg and diazepam (5mg/kg) significantly (p<0.05, 0.01) increased the post-treatment climbing time and reduced the latency to slide down in the climbing and inclined screen tests, respectively. The extract was not effective in the strychnine-induced seizure model, while in the picrotoxin test Albizia glaberrima extract at 100mg/kg significantly (p<0.05) reduced the duration of convulsion while reducing mortality at 400mg/kg, as was the case with diazepam (2mg/kg). The extract and diazepam significantly (p<0.01, 0.001) increased onset and reduced duration of convulsion, with significant level of protection against convulsion and reduction in mortality in the PTZ-induced seizure model. Preliminary phytochemical screening of the extract revealed the presence of phenols>tannins>saponins>flavonoids. The extract was found to be relatively non-toxic when administered p.o. up to 5000mg/kg and the LD50 was 398.11mg/kg when administered i.p. CONCLUSIONS The aqueous leaf extract of Albizia glaberrima possesses dose-dependent anxiolytic/muscle relaxant (low dose) and sedative-hypnotic/anticonvulsant (high dose) activities possibly mediated via enhancement of GABAergic inhibitory actions.

Abstract
As part of our search of new bioactive triterpenoid saponins from Cameroonian Mimosaceae plants, phytochemical investigation of the roots of Albizia lebbeck led to the isolation of two new oleanane-type saponins, named lebbeckosides A-B (1-2). Their structures were established on the basis of extensive 1D and 2D NMR ((1)H, (13)C NMR, DEPT, COSY, TOCSY, ROESY, HSQC, and HMBC) and HRESIMS studies, and by chemical evidence. Compounds 1-2 were evaluated for their inhibitory effect on the metabolism of high grade human brain tumor cells, the human glioblastoma U-87 MG cell lines and the glioblastoma stem-like TG1 cells isolated from a patient tumor, and known to be particularly resistant to standard therapies. The isolated saponins showed significant cytotoxic activity against U-87 MG and TG1 cancer cells with IC50 values of 3.46 μM and 1.36 μM for 1, and 2.10 μM and 2.24 μM for 2, respectively.

Abstract
Anaerobic digestion (AD) is an attractive technology in tropical regions for converting locally abundant biomass wastes into biogas which can be used to produce heat, electricity, and transportation fuels. However, investigations on AD of tropical forestry wastes, such as albizia biomass and food wastes, such as taro, papaya, and sweet potato, are limited. In this study, these tropical biomass wastes were evaluated for biogas production by liquid AD (L-AD) and/or solid-state AD (SS-AD), depending on feedstock characteristics. When albizia leaves and chips were used as feedstocks, L-AD had greater methane yields (161 and 113 L kg(-1)VS, respectively) than SS-AD (156.8 and 59.6 L kg(-1)VS, respectively), while SS-AD achieved 5-fold higher volumetric methane productivity than L-AD. Mono-digestion and co-digestion of taro skin, taro flesh, papaya, and sweet potato achieved methane yields from 345 to 411 L kg(-1)VS, indicating the robustness of AD technology.

Abstract
BACKGROUND Hypoglycemic and/or anti-hyperglycemic activities have been recorded with numerous plants, many of which are used as traditional herbal treatments of diabetes. Albizzia Lebbeck Benth. stem bark have been used in traditional medicine along with some preliminary reports on its hypoglycemic action. The aim of present investigation was to evaluate the antidiabetic and antioxidant activities of methanolic extract of stem bark of Albizzia Lebbeck Benth. in streptozotocin induced diabetic rats. METHODS The powdered stem bark of Albizzia Lebbeck Benth.. was extracted with methanol (MeOH) using soxhlation method and subjected to phytochemical analysis. The methanol/dichloromethane extract of Albizzia Lebbeck Benth. (ALEx) was concentrated to dryness using Rotary Evaporator. Diabetes was experimentally induced in the rats by single intraperitoneal administration of Streptozotocin (60 mg/kg). They glycemic control was measured by the blood glucose, glycated heamoglobin and plasma insulin. The oxidative stress was evaluated in the liver and kidney by level of antioxidant markers and various biochemical parameters were assessed in diabetic control and extract treated rats. RESULTS Streptozotocin induced diabetic rats depicted the increased blood glucose levels, total cholesterol (TC), triglycerides (TG), low density lipoprotein cholesterol (LDL-c), diminished level of high density lipoprotein cholesterol (HDL-c) level and perturb level of antioxidant markers. Oral administration of MeAL at a concentration of 100, 200, 300 and 400 mg/kg b.w daily for 30 days results a momentous decrease in fasting blood glucose, glycated heamoglobin and enhancement of plasma insulin level as compared with STZ induced diabetic rats. Furthermore, it significantly (p < 0.05) decreased the level of TC, TG, and LDL-c, VLDL-c. While it increases the level of HDL-c to a significant (p < 0.05) level. The treatment also resulted in a marked increase in reduced glutathione, glutathione Peroxidase, catalase and superoxide dismutase and diminished level of lipid peroxidation in liver and kidney of STZ induced diabetic rats. Histopathological studies suggest the diminution in the pancreatic, liver and cardiac muscle damage. CONCLUSION Our research exertion clearly indicates the considerable antihyperglycemic, antihyperlipidemic, antioxidant & pancreas/renal/hepatic/cardiac protective action of ALEx.

Abstract
The antioxidative activities of the ethanol and aqueous extracts of the leaf and root samples of Albizia antunesiana were determined across a series of four in vitro models. The results showed that all the extracts had reducing power (Fe(3+)- Fe2+), DPPH, hydroxyl and nitric oxide radical scavenging abilities. The ethanol root extract had more potent antioxidant power in all the experimental models and possesses a higher total phenol content of 216.6 +/- 6.7 mg/g. The GC-MS analysis of the aqueous and ethanol extracts of the roots and leaves indicated that several aromatic phenolic compounds, a coumarin and some common triterpenoids were present in these extracts. Data from this study suggest that the leaves and roots of Albizia antunesiana possessed antioxidative activities that varied depending on the solvents.

Abstract
The present investigation is an attempt to scientifically validate the traditional use of the roots of the plant Albizzia lebbeck in Ayurvedic system of medicine for curing wounds. The study included phytochemical standardization of the ethanol root extract of A. lebbeck, which was further subjected to oral acute toxicity study. Wound-healing activity of the ethanol root extract was evaluated using incision and excision wound models. Biochemical parameters such as hydroxyproline, hexuronic acid, hexosamine, and antioxidant enzymes like superoxide dismutase, reduced glutathione and free radical parameters including lipid peroxidation and nitric oxide were evaluated on the 10th post-wounding day following dead space method. For confirmation of activity, histopathology of the wounds and granulation tissues from excision and dead space wound model were performed. The study also included assessment of antibacterial activity of ethanol root extract against strains implicated in wound infection. The ethanol root extract was found to be highly rich in flavonoids, saponins, phenols, and tannins, while the amount of rutin was found to be 4.66 % w/w. It significantly increased the wound breaking strength showing a ceiling effect at 500 mg/kg p. o. The ethanol root extract at 500 mg/kg p. o. depicted an optimum wound contraction on the 18th day, while complete wound contraction was observed at the 22nd post wound day. It also demonstrated a significant increase in dry tissue weight, total protein, hydroxyproline, hexosamine, hexuronic acid, superoxide dismutase, and reduced glutathione levels, whereas a decrease in the levels of lipid peroxidation and nitric oxide was also observed with a potential antibacterial activity. Histopathological studies revealed a normal epithelization and fibrosis which was evidenced through an increase in collagen density. Thus, the study scientifically validated the wound-healing activity of the ethanol root extract along with a potential antibacterial property which may be attributed to the enhanced collagen synthesis and a potential antioxidant activity.

Abstract
CONTEXT Traditional knowledge of herbal remedies plays an important role in the search for more effective alternative treatment of a variety of disorders. The ethnobotanical surveys in southern Thailand have revealed that 35 Thai herbal formulas have been used by Thai traditional healers against dental caries. However, the scientific evaluation to confirm their rational uses is scarce. OBJECTIVE To test in vitro anti-Streptococcus mutans activity of Thai herbal formulas used against dental caries (THF-DC). MATERIALS AND METHODS Ethanol extracts of Thai herbal formulas were evaluated for antibacterial activity against S. mutans. Agar disc diffusion was employed as a preliminary screening assay, followed by broth microdilution assay to assess minimum inhibitory concentration (MIC). Furthermore, medicinal plants contained in the most active THF-DC were investigated for their phytochemicals. RESULTS Eleven THF-DC extracts exhibited clear inhibition zones of 7.0-22.5 mm against S. mutans. Subsequent determination of their MIC revealed that the formula containing Albizia myriophylla Benth. (Leguminosae), Alpinia galanga (L.) Willd. (Zingiberaceae), Avicennia marina (Forssk.) Vierh. (Acanthaceae), and Ocimum sanctum L. (Lamiaceae) was the most active, with MIC at 250 µg/mL. Among these medicinal plants, A. myriophylla gave the strongest activity with MIC at 3.9 µg/mL, followed by A. marina with MIC at 62.5 µg/mL. Various classes of bioactive phytochemicals including tannins, flavonoids, alkaloids, and terpenoids were found in these extracts. CONCLUSION Anti-S. mutans activity of THF-DC extracts was established. Further investigations may be required for the isolation and chemical characterization of the active ingredients in A. myriophylla.

Abstract
Albizia species have been shown to have anti-inflammatory and anti-allergic properties. However, efficient analytical methods for identification of their active constituents are still lacking. Ultra-performance liquid chromatography coupled with electrospray ionization-quadrupole time-of-flight mass spectrometry (UPLC-ESI-QTOF-MS) was used to study the phenolic composition of the ethanolic extracts of different parts (flowers, leaves, pods and bark) of A. chinensis. In addition, the antioxidant activity of the ethanolic extracts was evaluated by the 1,1-diphenyl-2-picryl hydrazyl (DPPH) free-radical and 2,2'-azino-bis(3-ethylbenzthiazoline-6-sulfonic acid (ABTS) radical cation scavenging methods. Four compounds were isolated from the ethanolic extract of the flowers and characterized by 1H and 13C NMR spectroscopy as quercetin-3-O-rhamnoside, quercetin, quercetin-3-O-arabinofuranoside, and myricetin-3-O-rhamnoside. Separation and quantification of the phenolics was accomplished using a reversed-phase BEH C18 column with the mobile phase of methanol-water (0.05% formic acid), and detection wavelengths of 360 and 254 nm.

Abstract
A monomeric 5.5-kDa protein with hemolytic activity toward rabbit erythrocytes was isolated from seeds of Albizia lebbeck by using a protocol that involved ion-exchange chromatography on Q-Sepharose and SP-Sepharose, hydrophobic interaction chromatography on Phenyl-Sepharose, and gel filtration on Superdex 75. It was unadsorbed on both Q-Sepharose and SP-Sepharose, but adsorbed on Phenyl-Sepharose. Its hemolytic activity was fully preserved in the pH range 0-14 and in the temperature range 0-100 °C, and unaffected in the presence of a variety of metal ions and carbohydrates. The hemolysin reduced viability of murine splenocytes and inhibited proliferation of MCF-7 breast cancer cells and HepG2 hepatoma cells with an IC₅₀ of 0.21, 0.97, and 1.37 μM, respectively. It impeded mycelial growth in the fungi Rhizoctonia solani with an IC₅₀ of 39 μM but there was no effect on a variety of other filamentous fungi, including Fusarium oxysporum, Helminthosporium maydis, Valsa mali and Mycosphaerella arachidicola. Lebbeckalysin inhibited growth of Escherichia coli with an IC₅₀ of 0.52 μM.

Abstract
Three triterpene glycosides and two known ones were isolated from the bark of Albizia procera by using chromatographic techniques. The structures of the compounds were determined to be 3-O-beta-D-xylopyranosyl-(1-->2)-beta-D-galactopyranosyl-(1-->6)-2-acetamido-2-deoxy-beta-D-glucopyranosyl echinocystic acid 16-O-beta-D-glucopyranoside, 3-O-beta-D-xylopyranosyl-(1-->2)-alpha-L-arabinopyranosyl-(1-->6)-2-acetamido-2-deoxy-beta-D-glucopyranosyl echinocystic acid 16-O-beta-D-glucopyranoside and 3-O-alpha-L-arabinopyranosyl-(1-->2)-alpha-L-arabinopyranosyl-(1-->6)-2-acetamido-2-deoxy-beta-D-glucopyranosyl echinocystic acid 16-O-beta-D-glucopyranoside. Their structures were determined by NMR techniques including HOHAHA, (1)H-(1)H COSY, ROE, HMQC and HMBC experiments together with FABMS as well as acid hydrolysis. To the best of our knowledge, the new compounds are considered the first examples of echinocystic acid 3,16-O-bisglycosides. In contrast to other cytotoxic echinocystic acid glycosides with N-acetyl glucosamine unit, the new glycosides were found inactive when assayed by MTT method for their cytotoxicities against the human tumor cell lines HEPG2, A549, HT29 and MCF7. The results showed the importance of the free hydroxyl group at the aglycone C-16 for exhibiting cytotoxic properties.

The core tablets were compression-coated with 300 and 400mg of 100% khaya gum, 100% albizia gum and a mixture of khaya and albizia gum (1:1). Drug release studies were carried out in 0.1M HCI (pH 1.2) for 2h, Sorensen's buffer (pH 7.4) for 3 h and then in phosphate-buffered saline (pH 6.8) or in simulated colonic fluid for the rest of the experiment to mimic the physiological conditions from the mouth to colon. The results indicated that khaya and albizia gums were capable of protecting the core tablet in the physiological environment of the stomach and small intestine, with albizia gum showing greater ability than khaya gum. The release from tablets coated with the mixture of khaya and albizia gums was midway between the two individual gums, indicating that there was no interaction between the gums. Studies carried out using rat caecal matter in phosphate-buffered saline at pH 6.8 (simulated colonic fluid) showed that the gums were susceptible to degradation by the colonic bacterial enzymes, leading to release of the drug. The results demonstrate that khaya gum and albizia gum have potential for drug targeting to the colon.

Abstract
Two new oleanane-type saponins, coriariosides A (1) and B (2), along with a known saponin, gummiferaoside C (3), were isolated from the roots of Albizia coriaria. Their structures were established by extensive analysis of 1D and 2D NMR experiments (COSY, ROESY, TOCSY, HSQC, and HMBC) and mass spectrometry. Compounds 1 and 3 when tested for cytotoxicity against two colorectal human cancer cells showed activity against the HCT 116 (IC50 4.2 microM for 1 and 2.7 microM for 3) and HT-29 (IC50 6.7 microM for 1 and 7.9 microM for 3) cell lines.

Abstract
PURPOSE The purpose of this study was to investigate the anti-angiogenic properties of julibroside J(8), a triterpenoid saponin isolated from Albizia julibrissin. METHODS In the presence of juliborside J(8,) the growth of human microvascular endothelial cells (HMEC-1), four human tumor cell lines, and a normal cell line (MRC-5) was evaluated by MTT assay. The in vivo anti-angiogenic effect of julibroside J(8) was evaluated on a chorioallantoic membrane (CAM) and in transplanted colon carcinoma cells in a nude mice neovascularisation model. RESULTS Treatment with 0.5-4 microg/ml julibroside J(8) resulted in dose-dependent inhibition of growth, migration, and tube formation in HMEC-1 cells; julibroside J(8) also inhibited the formation of microvessels on CAM at a concentration of 10-50 microg/egg and reduced vessel density within tumor at a concentration of 0.5-3mg/kg. CONCLUSIONS Julibroside J(8) may be a potent anti-angiogenetic and cytotoxic drug; further investigation is warranted.

Abstract
Albizia schimperiana Oliv. (Leguminosae) is a tree distributed in the highland of Kenya, where it is used as a traditional medicine for the treatment of bacterial and parasitic infections, notably pneumonia and malaria, respectively. Bioassay guided isolation of the CH2Cl2-MeOH 1:1/ MeOH-H20 9:1 (mixed) extract of A. schimperiana afforded the new bioactive macrocyclic spermine alkaloid, namely 5,14-dimethylbudmunchiamine L1 (1) and three known budmunchiamine analogs 2-4. The structures of the compounds 1-4 were determined by 1D and 2D NMR data, including COSY, HMQC, and HMBC experiments, and ESI-HRMS. Compounds 1 and 3 exhibited significant in vitro antimicrobial activity against a panel of microorganisms, including C neoformans, methicillin-resistant S. aureus, E. coli, M. intracellulare, and A. fumigatus. In Saddition, they demonstrated strong in vitro antimalarial activities against chloroquine-susceptible (D6) and -resistant (W2) strains of Plasmodium falciparum with IC50s ranging from 120-270 ng/mL. Compounds 1-4 were also evaluated for cytotoxic activity against selected human cancer cell lines and mammalian kidney fibroblasts (VERO cells). It was observed that hydroxyl substitution of the side chain of the budmunchiamines dramatically reduced the cytotoxicity and antimicrobial activity of the alkaloids 2 and 4 without decreasing antimalarial activity.

Abstract
BACKGROUND Respiratory Tract infections continue to be a major cause of morbidity and mortality world wide. There is a failure to treat respiratory infections due to the emergence of antibiotic resistant strains among the most common respiratory pathogens. OBJECTIVES To evaluate the in vitro antibacterial activities of two traditionally used plants: Albizia gummifera (Ambabesa-Muka, Oromifa, Sessa-Amharic.) and Ferula communis (Doge-Oromifa, Dog-Amharic) against clinical isolates of S. pyogenes and S. pneumoniae. METHODS The study involving the antibacterial susceptibility test of traditionally used plant species against Gram-positive bacterial pathogens was conducted over a period of 5 months (January - August, 2004) at the Ethiopian Health, and Nutrition Research Institute. The in vitro antibacterial activities of 80% methanol crude extracts prepared from the seeds of Ablizia gummifera and, roots of Ferula communis as well as their respective hydro alcoholic solvent fractionates of both plant species were tested for inhibitory activity against the clinical isolates of six S. pneumonae and twenty two S. pyogenes using agar dilution method. RESULTS Eighty percent ethanol solubilized fractions of both plants were found to have antibacterial effects to all assayed bacteria while aqueous solubilized fractions did not exhibit any effect. Minimum inhibitory concentration (MIC) of the 80% ethanol solubilized fractions was determined and the MIC of the fractions ranged from 500 mg/ ml to 1000 mg/ml for both plants showing the extracts may contain bioactive compounds of therapeutic interest. CONCLUSION All extracts showed antibacterial activities against clinical isolates of S. pyogenes and S. pneumoniae. The extracts may contain compounds with potential therapeutic activity. Further purification and identification are needed to be tested using animal models.

Abstract
A new triterpenoid, saponin hehuanoside A, was isolated together with the known triterpenoid saponins 2, 3, and 4 from the stem bark of Albizia julibrissin. With the help of chemical and spectral analyzes (IR, MS, 1D-NMR, and 2D-NMR), the structure of the new triterpenoid saponin was elucidated as 21-O-[(6S)-2-trans-2,6-dimethyl-6-O-beta-d-quinovopyranosyl-2,7-octadienoyl]-3-O-beta-d-xylopyranosyl-(1 --> 2)-beta-d-fucopyranosyl-(1 --> 6)-beta-d-2-deoxy-2-acetamidoglucopyrasyl acacic acid 28-O-alpha-l-arabinofuranosyl-(1 --> 4)-[-beta-d-glucopyranosyl-(1 --> 3)]-alpha-l-rhamnopyranosyl-(1 --> 2)-beta-d-glucopyranosyl ester (1). Three known triterpenoid saponins 2-4 were identified on the basis of spectroscopic data.
