Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Ferula hermonis is a small shrub renowned for its aphrodisiac abilities. Middle East herbalists have utilized Ferula hermonis seed and root as an aphrodisiac folk medicine to treat women's frigidity and male erectile and sexual dysfunction. AIM OF THE STUDY Assessment of follicle-stimulating hormone-like (FSH), luteinizing hormone-like (LH), and estrogenic activities of the methanolic extract (ME) of the roots of Ferula hermonis on female reproductive function. MATERIALS AND METHODS The methanolic extract was prepared from the root of F. hermonis and studied at dose level 6 mg/kg in immature female rats for FSH-like, LH-like, and estrogenic activities. These activities were determined by analyzing gross anatomical features, relative organ weight, and serum level of FSH, LH, progesterone and estrogen hormones, and histopathological characteristics. Quantification of the main phytoestrogenic component ferutinin carried out by HPLC. In addition, molecular docking for the binding affinity of ferutinin inside active sites of both estrogen receptor alpha (ERα) and FSH receptor (FSHR) was performed to predict the potential role of ferutinin in regulating the female reproductive process. RESULTS Ferula hermonis (ME) showed potent FSH-like, LH-like activities and moderate estrogenic effect at the dose of 6 mg/kg. The content of ferutinin in F. hermonis was estimated to be 92 ± 1.33 mg/g of the methanolic extract. Molecular docking of ferutinin with ERα and FSHR displayed strong interaction with target proteins. CONCLUSIONS Based on results, it can be concluded that Ferula hermonis can be considered as a suitable female fertility improving agent.

Abstract
Fungi are among the biotic agents that can cause deterioration of building stones and cultural heritage. The most common methods used to control fungal spread and growth are based on chemical pesticides. However, the massive use of these synthetic chemicals produces heavy environmental pollution and risk to human and animal health. Furthermore, their use is time dependent and relies on the repetition of treatments, which increases the possibility of altering building stones and culture heritage through environmental contamination. One alternative is the use of natural products with high antifungal activity, which can result in reduced toxicity and deterioration of archeological remains. Recently, three fungal strains, namely Aspergillus niger, Alternaria alternata and Fusarium oxysporum, were isolated as damaging agents from the external tuff wall of the Roman remains "Villa of Poppea" in Oplontis, Naples, Italy. In this manuscript, three selected fungal metabolites, namely cyclopaldic acid, cavoxin and epi-epoformin, produced by fungi pathogenic for forest plants, were evaluated as potential antifungal compounds against the above fungi. Cavoxin and epi-epoformin showed antifungal activity against Asperigillus niger and Fusarium oxysporum, while cyclopaldic acid showed no activity when tested on the three fungi. The same antifungal activity was observed in vitro experiments on infected stones of the Neapolitan yellow tuff (NYT), a volcanic lithotype widely diffused in the archeological sites of Campania, Italy. This study represents a first step in the use of these two fungal metabolites to allow better preservation of artworks and to guarantee the conditions suitable for their conservation.

Abstract
Thinning is a common viticulture practice in warm climates, and it is applied to increase the quality of the harvest. Thinning clusters are usually discarded, and they are considered another oenological industry waste. To valorize this by-product, the phenolic content and antioxidant activity of three red varieties (Tempranillo, Cabernet Sauvignon, and Syrah), thinned at three different times between veraison and harvest, were studied: the first at the beginning of the veraison stage, in a low ripening stage; the second in an intermediate ripening stage; and, finally, the third sampling in the highest ripening stage. These by-products showed high values of total phenolic contents (10.66–11.75 mg gallic acid equivalent/g), which is of the same order as or even higher than that found in grape pomace. In thinned grape were identified 24 phenolic compounds, being the flavan-3-ols (catechin and epicatechin) of particular interest, with mean contents ranging from 105.1 to 516.4 mg/kg of thinned grape. Antioxidant activity similar to that of the vintage grape was found. It is concluded that thinned grape is a good source of phenolic compounds. Its content does not depend mainly on the grape variety; however, it has been possible to establish differences based on the maturity stage of the thinning grapes: the intermediate ripeness stage, with a Brix degree in the range of 15–16 for this area, would be the optimum collection time for cluster thinning. In this intermediate ripeness stage, thinning grapes present a higher antioxidant activity and there is also appreciable anthocyanin content, which is not found for the lowest ripeness stage, since these samples present an intermediate composition in all the families of determined phenolic compounds: anthocyanins, flavonols, flavan-3-ols, cinnamic acids, and benzoic acids. It is important to note that the experiments in this study have been carried out with whole tinned grapes, without separating the skin or the seeds.

Abstract
Moving cannabinoid production away from the vagaries of plant extraction and into engineered microbes could provide a consistent, purer, cheaper and environmentally benign source of these important therapeutic molecules, but microbial production faces notable challenges. An alternative to microbes and plants is to remove the complexity of cellular systems by employing enzymatic biosynthesis. Here we design and implement a new cell-free system for cannabinoid production with the following features: (1) only low-cost inputs are needed; (2) only 12 enzymes are employed; (3) the system does not require oxygen and (4) we use a nonnatural enzyme system to reduce ATP requirements that is generally applicable to malonyl-CoA-dependent pathways such as polyketide biosynthesis. The system produces ~0.5 g l-1 cannabigerolic acid (CBGA) or cannabigerovarinic acid (CBGVA) from low-cost inputs, nearly two orders of magnitude higher than yeast-based production. Cell-free systems such as this may provide a new route to reliable cannabinoid production.

Abstract
Phenoxy acid herbicides are used worldwide and are potential contaminants of drinking water. Reversed phase high-performance liquid chromatography (RP-HPLC) is commonly used to monitor phenoxy acid herbicides in water samples. RP-HPLC retention of phenoxy acids is affected by both mobile phase composition and pH, but the synergic effect of these two factors, which is also dependent on the structure and pKa of solutes, cannot be easily predicted. In this paper, to support the setup of RP-HPLC analysis of phenoxy acids under application of linear mobile phase gradients we modelled the simultaneous effect of the molecular structure and the elution conditions (pH, initial acetonitrile content in the eluent and gradient slope) on the retention of the solutes. In particular, the chromatographic conditions and the molecular descriptors collected on the analyzed compounds were used to estimate the retention factor k by Partial Least Squares (PLS) regression. Eventually, a variable selection approach, Genetic Algorithms, was used to reduce the model complexity and allow an easier interpretation. The PLS model calibrated on the retention data of 15 solutes and successively tested on three external analytes provided satisfying and reliable results.

Abstract
The fungus Neonectria discophora SNB-CN63 has been isolated from the nest of the termite Nasutitermes corniger found in French Guiana. From the ethyl acetate extract of fungal culture, bioassay guided fractionation led to the isolation of fourteen ilicicolinic acids and ilicicolinal derivatives. Their structures were elucidated by analyses of 1D and 2D NMR and MS spectroscopic data. All metabolites were tested against several microbial pathogens and six displayed antimicrobial activities with MIC <16 μg/mL on T. rubrum, Staphylococcus aureus and methicillin-resistant S. aureus. Based on their structural similarities, a common biosynthetic pathway is proposed for all isolated metabolites.

Abstract
Platinum-based anticancer drug therapies can cause renal damage and apoptotic kidney cell damage. The development of reno- and kidney-protective molecules is therefore urgently required. To address this challenge, we explored secondary metabolites of termite-associated Streptomyces sp. RB1 isolated from the cuticle of the South African termite, Macrotermes natalensis for their renoprotective ability using bioassay-guided fractionation and LLC-PK1 cells. Chemical investigation of the MeOH extract of Streptomyces sp. RB1 resulted in the isolation and identification of a renoprotective metabolite, 1-O-(2-aminobenzoyl)-α-l-rhamnopyranoside (ABR) (1) from the active fraction, which ameliorated cisplatin-induced cytotoxicity to 80% of the control value at 25 μM. Upregulated phosphorylation of c-Jun N-terminal kinases (JNK) and p38 following cisplatin treatment was markedly decreased after pre-treatment of cells with ABR. In addition, levels of cleaved caspase-3 and the percentage of apoptotic cells were also significantly reduced after pre-treatment with ABR. These findings provide experimental evidence that blocking the MAPK signaling cascade plays a critical role in mediating the renoprotective effect of ABR, which may inspire the development of novel therapeutic substances to prevent anticancer drug-induced nephrotoxicity.

Abstract
A new anthranilic acid derivative (1) was isolated from a Philippine sponge, Oscarella stillans (Bergquist and Kelly). The structure of compound 1, named oscarellin, was determined as 2-amino-3-(3'-aminopropoxy)benzoic acid from spectroscopic data and confirmed by synthesis. We examined the immunomodulating effect of compound 1 and its mechanism in lipopolysaccharide (LPS)-stimulated RAW 264.7 macrophages. Our data indicated that the expression of tumor necrosis factor-α (TNF-α) and interleukin (IL)-6 were significantly reduced by the pretreatment of 1 (0.1-10 μM) for 2 h. In addition, compound 1 suppressed activation of extracellular signal-regulated kinase 1/2 (ERK1/2) and c-Jun NH2-termimal kinase (JNK), but not p38 mitogen-activated protein kinase (MAPK) in LPS-stimulated RAW 264.7 cells. Compound 1 abrogated LPS-induced nuclear factor-κB (NF-κB) and activator protein-1 (AP-1) activities, whereas the induction of activating transcription factor-3 (ATF-3) was increased. Taken together, our results suggest that compound 1 attenuates pro-inflammatory cytokines via the suppression of JNK, ERK, AP-1, and NF-κB and the activation of the ATF-3 signaling pathway.

The chemical structures of the new compounds were elucidated by spectroscopic techniques. The anti-inflammatory effects of these compounds were determined on LPS-stimulated RAW 264.7 cell line. Some of the tested compounds (2, 3, 4, 6, 7) reduced the NO production in a dose-dependent manner, while 6 and 7 decreased PGE2 production in a dose-dependent manner, without altering cell viability. Data presented in this research indicated that Tabebuia avellanedae's ethnopharmacological action of treating inflammatory diseases was based on the constituents which exert a significant anti-inflammatory effect on inflammatory responses.

Abstract
The anaerobic degradation of four major constituents from purified terephtalic acid production wastewater in sequential two expanded granular sludge bed (EGSB) reactors was studied. The performance of the system was evaluated in terms of chemical oxygen demand (COD) removal efficiencies, methane production, stability, granular sludge adaptability as well as reversion of bacterial inhibition. With volumetric loading rates of 1.9-25 kg-COD m(-3) d(-1) and terephtalate and p-toluate of 584-821 mg L(-1), average removal efficiencies of 97.6% and 75.2% were achieved in the EGSB reactors, respectively. In these conditions, gas production reached a total methane production rate of 0.33 L g-COD(-1) in the two-stage EGSB reactor system. The disturbance of the EGSB reactors was observed at a feed concentration above around 6.9 g-COD L(-1) because of higher influent COD concentration compared to other experiments.

Abstract
Members of the fungal genus Exophiala are common saprobes in soil and water environments, opportunistic pathogens of animals, or endophytes in plant roots. Their ecological versatility could imply a capacity to produce diverse secondary metabolites, but only a few studies have aimed at characterizing their chemical profiles. Here, we assessed the secondary metabolites produced by five Exophiala sp. strains of a particular phylotype, isolated from roots of Microthlaspi perfoliatum growing in different European localities. Exophillic acid and two previously undescribed compounds were isolated from these strains, and their structures were elucidated by spectroscopic methods using MS, 1D and 2D NMR. Bioassays revealed a weak activity of these compounds against disease-causing protozoa and mammalian cells. In addition, 18 related structures were identified by UPLC/MS based on comparisons with the isolated structures. Three Exophiala strains produced derivatives containing a β-d-glucopyranoside moiety, and their colony morphology was distinct from the other two strains, which produced derivatives lacking β-d-glucopyranoside. Whether the chemical/morphological strain types represent variants of the same genotype or independent genetic populations within Exophiala remains to be evaluated.

Abstract
Polluxochrin (1) and dioschrin (2), two new dimers of sulochrin linked by thioether bonds, were purified from an Alternaria sp. isolate obtained from a Hawaiian soil sample. The structures of the two metabolites were established by NMR, mass spectrometry data, and X-ray analysis. Metabolite 1 was determined to be susceptible to intramolecular cyclization under aqueous conditions, resulting in the generation of 2 as well as another dimeric compound, castochrin (3). An additional nine new metabolites were also obtained, including four new pyrenochaetic acid derivatives (8-11), one new asterric acid analogue (13), and four new secalonic acid analogues (14-17). Bioassay analysis of these compounds revealed 1-3 displayed antimicrobial and weak cytotoxic activities.

Abstract
Gerbera anandria (Compositae) was extracted with 75% ethanol and the residue was fractionated using light petroleum, chloroform and ethyl acetate. The constituents of the extracts were separated by column chromatography employing solvents of different polarity. Column chromatography of the light petroleum fraction resulted in the isolation of methyl hexadecanoate, while the chloroform fraction afforded xanthotoxin, 2-hydroxy-6-methylbenzoic acid, 7-hydroxy-1(3H)-isobenzofuranone, a mixture of β-sitosterol and stigmasterol, and 8-methoxysmyrindiol and the ethyl acetate fraction gave gerberinside, apigenin-7-O-β-d-glucopyranoside and quercetin. A new coumarin, 8-methoxysmyrindiol, was found. The chemical structures of the isolated compounds were established by MS and NMR (HSQC, HMBC). Free radical scavenging and cytotoxic activities of crude extracts and 8-methoxysmyrindiol were further investigated. The ethyl acetate phase exerted the strongest DPPH free radical scavenging activity in comparison to the other fractions. The coumarin 8-methoxysmyrindiol demonstrated cytotoxicity against multiple human cancer cell lines, with the highest potency in HepG2 cells.

Abstract
The known prenylated benzoic acid derivative 3-geranyl-4-hydroxy-5-(3″,3″-dimethylallyl)benzoic acid (1) and two new chromane natural products were isolated from the methanolic extract of the leaves of Piper kelleyi Tepe (Piperaceae), a midcanopy tropical shrub that grows in lower montane rain forests in Ecuador and Peru. Structure determination using 1D and 2D NMR analysis led to the structure of the chromene 2 and to the reassignment of the structure of cumanensic acid as 4, an isomeric chromene previously isolated from Piper gaudichaudianum. The structure and relative configuration of new chromane 3 was determined using 1D and 2D NMR spectroscopic analysis and was found to be racemic by ECD spectropolarimetry. The biological activity of 1-3 was evaluated against a lab colony of the generalist caterpillar Spodoptera exigua (Noctuidae), and low concentrations of 2 and 3 were found to significantly reduce fitness. Further consideration of the biosynthetic relationship of the three compounds led to the proposal that 1 is converted to 2 via an oxidative process, whereas 3 is produced through hetero-[4+2] dimerization of a quinone methide derived from the chromene 2.

Abstract
In vitro screening of 17 Alpine lichen species for their inhibitory activity against 5-lipoxygenase, microsomal prostaglandin E2 synthase-1 and nuclear factor kappa B revealed Cetrelia monachorum (Zahlbr.) W.L. Culb. & C.F. Culb. As conceivable source for novel anti-inflammatory compounds. Phytochemical investigation of the ethanolic crude extract resulted in the isolation and identification of 11 constituents, belonging to depsides and derivatives of orsellinic acid, olivetolic acid and olivetol. The two depsides imbricaric acid (4) and perlatolic acid (5) approved dual inhibitory activities on microsomal prostaglandin E2 synthase-1 (IC50 = 1.9 and 0.4 µM, resp.) and on 5-lipoxygenase tested in a cell-based assay (IC50 = 5.3 and 1.8 µM, resp.) and on purified enzyme (IC50 = 3.5 and 0.4 µM, resp.). Additionally, these two main constituents quantified in the extract with 15.22% (4) and 9.10% (5) showed significant inhibition of tumor necrosis factor alpha-induced nuclear factor kappa B activation in luciferase reporter cells with IC50 values of 2.0 and 7.0 µM, respectively. In a murine in vivo model of inflammation, 5 impaired the inflammatory, thioglycollate-induced recruitment of leukocytes to the peritoneum. The potent inhibitory effects on the three identified targets attest 4 and 5 a pronounced multi-target anti-inflammatory profile which warrants further investigation on their pharmacokinetics and in vivo efficacy.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE In the theory of traditional Chinese medicine, pulmonary fibrosis (PF) belongs to pulmonary arthralgia, which means blood stasis in lung tissue. The roots of Paeonia lactiflora Pall are usually used to relieve the symptoms of this disease by promoting blood circulation and removing blood stasis. Paeoniflorin, the main active ingredient of P. lactiflora, may have anti-PF potential. AIM OF STUDY This study aimed to investigate the effects and underlying mechanisms of paeoniflorin on bleomycin (BLM)-induced PF in mice. MATERIALS AND METHODS The PF model was established in mice by an intratracheal instillation of BLM. Paeoniflorin (25, 50, 100mg/kg) and prednisone (6mg/kg), as a positive control, were orally administered for consecutive 21 days. Histopathological changes were evaluated by hematoxylin and eosin stain and Masson's trichrome stain. The content of hydroxyproline was detected by using kits. The contents of type I collagen, TGF-β1 and IFN-γ were detected by ELISA. The levels of α-SMA, Smad4, Smad7 and the phosphorylations of Smad2/3 were detected by western blot. The mRNA expressions of MMP-1 and TIMP-1 were detected by RT-PCR. RESULTS In mice treated with BLM, paeoniflorin (50mg/kg) significantly prolonged the survival periods, attenuated infiltration of inflammatory cells, interstitial fibrosis, and deposition of extracellular matrix in lung tissues. It also decreased the contents of hydroxyproline (a marker of collagens), type I collagen and α-SMA (an indicator of myofibroblasts) in lung tissues of mice. Paeoniflorin down-regulated the expressions of TGF-β1, Smad4 and the phosphorylations of Smad2/3, while up-regulated the expression of Smad7 in lung tissues. Moreover, paeoniflorin increased the content of IFN-γ. But, it only slightly affected mRNA expressions of MMP-1 and TIMP-1 in lung tissues of mice. CONCLUSIONS Paeoniflorin attenuates PF by suppressing type I collagen synthesis via inhibiting the activation of TGF-β/Smad pathway and increasing the expression of IFN-γ.

Abstract
Bu-yang-huan-wu-tang (BYHWT) is a popular Traditional Chinese Medicine formula consisting of seven herbal medicines (Astragalus membranaceus, Angelica sinensis, Paeonia lactiflora, Ligusticum chuanxiong, Carthamus tinctorius, Amygdalus persica and Pheretima aspergillum), that has been used in China for centuries to overcome stroke-induced disability. To ensure the consistency of quality, a reliable analytical method is required, therefore, we developed a liquid chromatography with tandem mass spectrometry (LC-MS/MS) method for quantitative analysis of the major constituents in BYHWT. The herbal ingredients consisting of the cycloartane-type triterpene glycosides of astragaloside I, astragaloside II and astragaloside IV; isoflavones of formononetin, ononin calycosin, calycosin-7-O-β-d-glucoside; ligustilide and paeoniflorin were separated on a C18 column with gradient elution of methanol/10 mM ammonium acetate buffer–formic acid (100:0.1, v/v). This study was performed by a mass spectrometer using electrospray ionization (ESI) with positive ionization ions monitored in the multiple reaction-monitoring (MRM) mode. The linearity, accuracy, precision, limit of detection (LOD) and lower limit of quantification (LLOQ) were validated for this quantification method, and the sensitivity, reliability and reproducibility were all confirmed. The experiments provided a good method for analyzing BYHWT extracts. This study also quantitated the active components in various brands of commercially available products. The results indicated that the pharmaceutical industrial products of BYHWT exhibited considerable variation in their contents of the herbal compounds.

Abstract
Paeonia suffruticosa, an important traditional herbal medicine, has been reported to prevent the pathogenesis of diabetic nephropathy through modulating advanced glycation end products-induced inflammatory and oxidative stress responses. However, little was known about the protective effect of the two major compounds in P. suffruticosa, paeoniflorin and oxypaeoniflora, on advanced glycation end products-induced mesangial cell damage. In the present study, we investigated the protective activities of paeoniflorin and oxypaeoniflora on advanced glycation end product-induced oxidative stress and inflammation in mesangial cells HBZY-1. The IC50 values of paeoniflorin and oxypaeoniflora for inhibiting 2,2'-azinobis-(3-thylbenzothiazoline-6-sulfonic acid) formation were 4.197 × 10-4 M and 1.002 × 10-4 M, respectively. The pretreatment with paeoniflorin and oxypaeoniflora (10-8-10-4 M) significantly increased advanced glycation end product-induced glutathione peroxidase and catalase activities. In the coculture system of HBZY-1 and macrophages, paeoniflorin and oxypaeoniflora could inhibit remarkably the migration of macrophages. Furthermore, paeniflorin and oxypaeniflora attenuated markedly advanced glycation end products-induced inflammation cytokines interleukin-6 and monocyte chemoattractant protein-1 levels in ELISA and western blot analysis in a dose-dependent manner. Taken together, our data provided the reliable evidence that paeniflorin and oxypaeniflora were able to attenuate advanced glycation end products-induced oxidative damage and inflammation in mesangial cells. Paeniflorin and oxypaeniflora might therefore have a beneficial effect in the treatment of diabetic nephropathy.

Abstract
A label-free method based on spectral correlation interferometry has been developed for highly sensitive detection of pyrethroids by competitive immunoassay on the surface of sensor chips made of widely available microscopy glass cover slips. It is shown that the method allows independent optimization of each step of the sensor surface modification. This fact may be used to increase the efficiency of development of protocols for a wide spectrum of immunoassays that employ glass surface as a solid phase. Detection of 3-phenoxybenzoic acid, which is one of the most stable metabolites of a large number of pyrethroids, on the surface of the optimized sensor chips has been demonstrated on the level of 15 pg/ml. That is 50 times better than the sensitivity of the enzyme-linked immunosorbent assay (ELISA).

Abstract
Two-stage upflow anaerobic sludge blanket (UASB) process was investigated as an efficient process configuration option for the treatment of purified terephthalic acid (PTA) wastewater. To study its feasibility in a defined condition, synthetic wastewater containing only the major pollutants (i.e., acetate, benzoate, terephthalate and p-toluate) was used. By focusing the role of the second stage on the p-toluate degradation, improved overall COD and p-toluate removal capacities of 4.18 and 1.35 g-thCOD/L·day could be achieved together with a complete COD removal efficiency. In this situation, all the pollutants except p-toluate were completely degraded in the first stage while 38 and 62% of p-toluate originally present in the wastewater were consecutively degraded in the individual stages. The concomitant methane production rate in each stage was 0.91 and 0.35 L/L·day respectively, and the methane yield on p-toluate was determined to be 0.12 L/g-thCOD. Batch tests using the granules obtained from each stage revealed that the acidogenic microorganisms enriched in both stages had a universal ability to degrade all aromatic pollutants present in the PTA wastewater. Moreover, image analysis using scanning electron microscope and confocal laser scanning microscopy combined with fluorescence in situ hybridization technique elucidated that the distribution of acidogens and methanogens within the granule was varied in each stage, which influenced the mass transfer regime resulting in the different pollutant degradation rates during the batch tests.

Abstract
The present work describes the preparation of two compounds considered to be likely precursors of an impurity present in samples of the color additives D&C Red No. 27 (Color Index 45410:1) and D&C Red No. 28 (Color Index 45410, phloxine B) submitted to the U.S. Food and Drug Administration for batch certification. The two compounds, 2-(2',4'-dihydroxy-3'-bromobenzoyl)-3,4,5,6-tetrachlorobenzoic acid (3BrHBBA) and its 5'-brominated positional isomer (5BrHBBA), both not reported previously, were separated from synthetic mixtures by vortex counter-current chromatography (VCCC). 3BrHBBA was prepared by chemoselective ortho-bromination of the dihydroxybenzoyl moiety. Two portions of the obtained synthetic mixture, 200mg and 210 mg, respectively, were separated by VCCC using two two-phase solvent systems that consisted of hexane-ethyl acetate-methanol-aqueous 0.2% trifluoroacetic acid (TFA) in the volume ratios of 8:2:5:5 and 7:3:5:5, respectively. These separations produced 35 mg and 78 mg of 3BrHBBA, respectively, each product of over 98% purity by HPLC at 254 nm. 5BrHBBA was prepared by monobromination of the dihydroxybenzoyl moiety in the presence of glacial acetic acid. To separate the obtained synthetic mixture, VCCC was performed in the pH-zone-refining mode with a solvent system consisting of hexane-ethyl acetate-methanol-water (6:4:5:5, v/v) and with TFA used as the retainer acid and aqueous ammonia as the eluent base. Separation of a 1-g mixture under these conditions resulted in 142 mg of 5BrHBBA of ∼ 99% purity by HPLC at 254 nm. The isolated compounds were characterized by high-resolution mass spectrometry and proton nuclear magnetic resonance spectroscopy.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Paeoniflorin (Pae) is extracted from the root of paeonia lactiflora which have attracted attention for anti-rheumatic and immune modulating properties. AIM OF THE STUDY To investigate the role of PI3K/Akt/mTOR signaling mediated by BAFF/BAFF-R in antibodies production and the regulation of Pae on the signaling pathway in rats with collagen-induced arthritis (CIA). MATERIALS AND METHODS CIA rats were randomly separated into different groups and treated with Pae (25, 100mg/kg) from day 18 to day 38 after immunization. The effects of Pae on B lymphocytes of CIA rats were evaluated by the levels of BAFF, anti-CII antibody, IgA, IgG and IgM, and the expressions of BAFF-R, PI3K, p-Akt and mTOR. RESULTS In CIA rats, the levels of anti-CII antibody, IgA, IgG and IgM in serum enhanced, BAFF, BAFF-R, PI3K, p-Akt and mTOR were highly expressed. Pae (100mg/kg) obviously decreased arthritis score, relieved ankle and paw swelling, improved spleen histopathology in CIA rats, decreased the levels of IgA, IgM, IgG and anti-CII antibody, and significantly decreased the expressions of BAFF, BAFF-R, PI3K, p-Akt and mTOR. CONCLUSION PI3K/Akt/mTOR signaling mediated by BAFF/BAFF-R participates in antibodies production by B lymphocytes of CIA rats. Pae had therapeutic effects on rats with CIA. These effects might be relative to regulating PI3K/Akt/mTOR signal mediated by BAFF/BAFF-R, and down regulate the antibodies production further.

Abstract
The paper is to report the development of a method of quantitative analysis of multi-components by high performance liquid chromatography (HPLC) for simultaneously determining paeoniflorin sulfonate (PS), paeoniflorin (PF) and albiflorin (AF) in sulfated Paeoniae Radix Alba. Moreover, the cytotoxicity of paeoniflorin sulfonate by MTT-assay and the acute toxicity of mice by administration of paeoniflorin sulfonate were evaluated. Chromatographic separation of paeoniflorin sulfonate, PF and AF were performed on a SHISEIDO CAPCELL PAK C18 column (250 mm x 4.6 mm, 5 microm) for HPLC and a mixture of acetonitrile and 0.02% phosphoric acid solution (15 : 85) as the mobile phase. As detector a spectrophotometer set at 230 nm; column temperature 30 degrees C; flow rate 1.0 mL x min(-1). The toxicity of paeoniflorin sulfonate was evaluated by in vitro cytotoxicity carried out on mouse and human primary hepatocytes, and by acute oral toxicity test carried out on mice. The calibration curve of paeoniflorin sulfonate, PF and AF revealed linearity in the range of 0.041 8 - 1.045 0, 0.023 5 - 0.587 5, and 0.039 8 - 0.995 0 mg x mL(-1), respectively (r > 0.999 8). The average recovery was ranged from 99.11% to 101.71%, RSD < 2%. Paeoniflorin sulfonate does not have any cytotoxicity to cells at all the tested concentrations (< or = 300 micromol x L(-1)) in the in vitro cytotoxicity assay. The maximum tolerance dose of paeoniflorin sulfonate solution and extraction of Paeoniae Radix Alba to mouse is 5 g x kg(-1) and 80 g x kg(-1) respectively. The contents of these three components in the samples were determined with the developed method. It is a rapid, convenient and accurate method to determine multi-components. The content of PF in sulfated Paeoniae Radix Alba is significantly lower, and there is negative correlationship between the content of paeoniflorin sulfonate and PF. The in vitro cytotoxicity assay and in vivo mouse acute toxicity test showed that there is no obvious toxicity of paeoniflorin sulfonate and water-soluble extract of sulfated Paeoniae Radix Alba.

Abstract
OBJECTIVE To establish a new rapid method to screen potential hepatoprotective compounds from traditional Chinese medicine, and identify the hepatoprotective compounds in Paeoniae Radix Rubra. METHOD Fluorescein diacetate labelled and MTT assay were applied for screening the hepatoprotective fractions on HepG2 cells exposed to galactosamine. The active fractions were analyzed by chromatography coupled with mass spectrometry. Finally, the hepatoprotective effects of the identified compounds were validated by hepatoprotective assay. RESULT Three hepatoprotective fractions were founded, in which three compounds were identified as paeoniflorin, ethyl palmitate and ethyl linoleate. Validation results indicated that all the three compounds can attenuate the galactosamine induced injury on HepG2 cells. CONCLUSION Paeoniflorin, ethyl palmitate and ethyl linoleate from paeoniae radix rubra showed potential hepatoprotective activity.

Abstract
Gaudichaudianic acid, a prenylated chromene isolated from Piper gaudichaudianum, has been described as a potent trypanocidal compound against the Y-strain of Trypanosoma cruzi. We herein describe its isolation as a racemic mixture followed by enantiomeric resolution using chiral HPLC and determination of the absolute configuration of the enantiomers as (+)-S and (-)-R by means of a combination of electronic and vibrational circular dichroism using density functional theory calculations. Investigation of the EtOAc extract of the roots, stems, and leaves from both adult specimens and seedlings of P. gaudichaudianum revealed that gaudichaudianic acid is biosynthesized as a racemic mixture from the seedling stage onward. Moreover, gaudichaudianic acid was found exclusively in the roots of seedlings, while it is present in all organs of the adult plant. Trypanocidal assays indicated that the (+)-enantiomer was more active than its antipode. Interestingly, mixtures of enantiomers showed a synergistic effect, with the racemic mixture being the most active.

Abstract
A bacterium capable of utilizing 3-phenoxybenzoic acid (3-PBA) as sole carbon source was isolated from petroleum-contaminated soil. This bacterium, designated as BA3, was identified as Sphingobium sp. according to its physiological & biochemical characteristic and the similarity analysis of its 16S rDNA sequence. Strain BA3 was able to degrade 99% of 100 mg x L(-1) 3-phenoxybenzoic acid within 60 h. The optimal pH and temperature for the degradation were 7.0 and 30 degrees C, respectively. The degradation efficiency was related positively to initial inoculum size. The pyrethroid hydrolase gene (pytH) gene was amplified from the genomic DNA of Sphingobium sp. JZ-2 by PCR. Recombinant plasmids pPYTH was constructed by ligating pytH gene into the broad host vector pBBRMCS- 5. Under the help of plasmid RK600, pPYTH was transferred into Sphingobium sp. BA3 to construct engineering strain BA3-pytH; Fenpropathrin degradation experiments showed that strain JZ-2 was able to degrade only 60% of 50 mg x L(-1) fenpropathrin in 48 h while engineering strain BA3-pytH was able to degrade over 95% of 50 mg x L(-1) fenpropathrin under the same conditions. Even more, BA3-pytH could rapidly degrade 3-PBA, metabolic products of pyrethroid insecticides, eliminating the inhibition of 3-PBA to pyrethroid hydrolase. Therefore, in contrast to strain JZ-2, engineering strain BA3-pytH had more advantages in bioremediation of pyrethroid insecticides contaminated environment.

Abstract
AIM OF THE STUDY Vessel endothelium injury caused by reactive oxygen species (ROS) including H(2)O(2) plays a critical role in the pathogenesis of cardiovascular disorders. Therefore, agents or antioxidants that can inhibit production of ROS has highly clinical values in cardiovascular therapy. Curculigoside is the major bioactive compounds present in Curculigo orchioides, and possess potent antioxidant properties against oxidative stress insults through undefined mechanism(s). The present study was designed to test the hypothesis that curculigoside can inhibit H(2)O(2)-induced injury in human umbilical vein endothelial cells. MATERIALS AND METHODS Human umbilical vein endothelial cells (HUVECs) were treated with curculigoside in the presence/absence of hydrogen peroxide (H(2)O(2)). The protective effects of curculigoside OP-D against H(2)O(2) were evaluated. RESULTS HUVECs incubated with 400 μM H(2)O(2) had significantly decreased the viability of endothelial cells, which was accompanied with apparent cells apoptosis, the activation of caspase-3 and the upregulation of p53 mRNA expression. In addition, H(2)O(2) treatment induced a marked increase of MDA, LDH content and in intracellular ROS, decreased the content of nitric oxide (NO) and GSH-Px activities in endothelial cells. However, pretreatment with 0.5.5,10 μM curculigoside resulted in a significant recovery from H(2)O(2)-induced cell apoptosis. Also, it decreased other H(2)O(2)-induced damages in a concentration-dependent manner. Furthermore, pretreatment with curculigoside decreased the activity of caspase-3 and p53 mRNA expression, which was known to play a key role in H(2)O(2)-induced cell apoptosis. CONCLUSION The present study shows that curculigoside can protect endothelial cells against oxidative injury induced by H(2)O(2), suggesting that this compound may constitute a promising intervention against cardiovascular disorders.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Paeoniflorin (PF) is the principal bioactive component of Radix Paeoniae alba, which is widely used in Traditional Chinese Medicine for the treatment of neurodegenerative disorders such as Parkinson's disease (PD). AIM OF THE STUDY To evaluate the neuroprotective effects of PF on MPP(+)- or acid- (pH 5.0) induced injury in cultured PC12 cells and to investigate the activity of autophagy-lysosome pathway (ALP). Amiloride (Ami), a non-selective blocker of acid-sensing ion channels (ASICs), as a positive control drug, since it is neuroprotective in rodent models of PD. MATERIALS AND METHODS The cell viability was analyzed with MTT assay. The cell injury was assessed by lactate dehydrogenase (LDH) assay. Flow cytometry and Western blot analysis were used to study the apoptotic, calcium influx and autophagic mechanisms. RESULTS Ami (100 microM) and PF (50 microM) both protected PC12 cells against MPP(+)- or acid-induced injury as assessed by MTT assay, lactate dehydrogenase release, and apoptosis rate. The concentrations of cytosolic free Ca(2+) were raised after exposure to MPP(+) or acidosis, while Ami and PF both reduced the influx of Ca(2+). More importantly, we found that the mechanisms of neuroprotective effects of Ami and PF were closely associated with the upregulation of LC3-II protein, which is specifically associated with autophagic vacuole membranes. Furthermore, application of MPP(+) or acid induced the overexpression of LAMP2a, which is directly correlated with the activity of the chaperone-mediated autophagy pathway. However, Ami and PF inhibited the overexpression of LAMP2a. CONCLUSIONS Our data provide the first experimental evidence that PF modulates autophagy in models of neuron injury, as well as providing the first indication of a relationship between ASICs and ALP.

Abstract
AIM OF THE STUDY In the Comoros Islands, the aerial parts of Flacourtia indica are used in traditional medicine to treat malaria. Because of the important use of this plant, the phytochemistry of the aerial parts was investigated. MATERIALS AND METHODS Three compounds were isolated from the decoction of this plant material, pyrocatechol, homaloside D and poliothrysoside. The in vitro antiplasmodial activity on the chloroquine-resistant strain (W2) of Plasmodium falciparum and the cytotoxicity on two complementary human cell lines (THP1, HepG2), of AcOEt extract obtained after liquid/liquid extraction of the decoction and pure compounds, were evaluated. RESULTS The poliothrysoside isolated from the AcOEt extract presented a strong antiplasmodial activity (IC(50)=7.4 microM) and a good selectivity index (>28) similar to chloroquine. CONCLUSION This study reports for the first time antiplasmodial activity for Flacourtia indica, for its AcOEt extract and the three major constituents and confirms its traditional use.

Abstract
The antidiabetic actions of Paeoniae Radix involve stimulating glucose uptake and reducing glucose absorption. However, the importance of this herb in the transcriptional regulation of hepatic gluconeogenesis has not previously been investigated, although hepatic gluconeogenesis contributes the most to fasting hyperglycemia. Using rats with streptozotocin-induced diabetes and db/db mice, the dose- and time-dependent suppressive effects of the ethanol extract of Paeoniae Radix (PR-Et) on diabetic hyperglycemia and phosphoenopyruvate carboxykinase (PEPCK) transcription are first demonstrated. Second, by employing H4IIE cells, the inhibitory action of PR-Et on both dexamethasone- and 8-bromo-cAMP-induced-PEPCK expression was also confirmed without causing any cytotoxicity. In addition, this inhibitory effect could be sustained for over 24 h with repeated treatment. Most importantly, PR-Et's action was unaffected by either insulin desensitization or palmitate stimulation. Finally, paeonol and paeoniflorin, two well-known constituents in Paeoniae Radix, did not suppress PEPCK expression at testing concentration. In conclusion, it was clearly demonstrated that transcriptional inhibition of gluconeogenesis is one of the important antidiabetic actions of Paeoniae Radix. Future development of this herb as a dietary supplement or drug should bring substantial benefits for the diabetic population.
