Abstract
Verthimia iphionoides extract from Palestine was tested in vitro for its antioxidant, antibacterial, and anticancer activities. Total phenolic content (TPC) and total flavonoid content (TFC) measurements were made concurrently. By using FRAP and DPPH methods, the antioxidant activity were measured spectrophotometrically. By using HPLC-PDA, phenolic and flavonoid compounds of the extract were determined. Results showed strong antioxidant activity of the plant extract revealed by inhibition of stable free radicals (DPPH test) and strong reducing ability (FRAP test). According to spectrophotometric methods for total phenolic compounds and total flavonoids content, the extracts were also found to be rich in polyphenolic compounds and flavonoids. Verthimia iphionoides extract had high antibacterial activity against three bacterial strains (Escherichia coli, Staphylococcus aureus, and Streptococcus aureus), with inhibition zone values of 14 mm, 25 mm, and 27 mm, respectively. Bioactivities were primarily attributed to plants’ abundant phenol-based chemical composition. Additionally, the extract was found to be abundant in phenolic and flavonoids, which improved its reducing activity and capacity to scavenge free radicals. Plant extracts were subjected to HPLC analysis, which identified different flavonoids and phenolic compounds in the extracts.

Abstract
Essential oils (EOs) are known for uses in various fields such as perfume, cosmetic, pharmaceutical and food industries. Agricultural wastes are among the resources of EOs that produced and disposed of in large quantities annually. Hence, in this study, for the first time, EOs available from pistachio fruit [fruit pistachio shells (FPS) and fruit pistachio cluster (FPC)] were used to the extraction of EOs. The Clevenger device and distilled water were used to extract EOs. The amount of total phenolic compounds (TPC) by Folin-ciocalteu reagent and the radical scavenging ability (RSA%) of FPS and FPC extracted by the soaking method were also measured. The RSA% of EOs and extracts in the presence of DPPH free radicals was evaluated by the IC50 index. Chemical composition of EOs detected by mass spectrometric gas chromatography. Notwithstanding amounts of extraction efficiency by water in the soaking method from FPS and FPC was 4.6% and 3.2% respectively, EOs extraction efficiency from FPC and FPS was 2.10% and 0.13% respectively. TPC in FPS and FPC was 958.38 and 796.25 mgGA/100g dry material respectively. The amount of IC50 of FPS was 3760.69 ppm and near to RSA% of BHT (2354.36 ppm). Statistical difference was observed between the RSA of EOs and positive control antioxidant (P < 0.05). The RSA of antioxidant extracts and TPC showed positively correlated. The major compounds identified in FPS were the D-limonene, α-thujene and terpinolene, abundance respectively, and the major components of FPC were α-thujene and α-pinene, abundance respectively.

Abstract
The aim of this study was to investigate the antioxidant potentials, subacute toxicity, and beneficiary effects of methanolic extract of pomelo (Citrus grandis L. Osbeck) in rats. Long Evans rats were divided into four groups of eight animals each. The rats were orally treated with three doses of pomelo (250, 500, and 1000 mg/kg) once daily for 21 days. Pomelo extract contained high concentrations of polyphenols, flavonoids, and ascorbic acid while exhibiting high 1,1-diphenyl-2-picrylhydrazyl radical scavenging activity and ferric reducing antioxidant power values. There was no significant change in the body weight, percentage water content, and relative organ weight at any administered doses. In addition, no significant alterations in the hematological parameters were also observed. However, rats which received 1000 mg/kg dose had a significant reduction in some serum parameters, including alanine transaminase (15.29%), alkaline phosphatase (2.5%), lactate dehydrogenase (15.5%), γ-glutamyltransferase (20%), creatinine (14.47%), urea (18.50%), uric acid (27.14%), total cholesterol (5.78%), triglyceride (21.44%), low-density lipoprotein cholesterol (40.74%), glucose (2.48%), and all atherogenic indices including cardiac risk ratio (24.30%), Castelli's risk index-2 (45.71%), atherogenic coefficient (42%), and atherogenic index of plasma (25%) compared to control. In addition, the highest dose (1000 mg/kg) caused a significant increase in iron (12.07%) and high-density lipoprotein cholesterol (8.87%) levels. Histopathological findings of the vital organs did not indicate any pathological changes indicating that pomelo is nontoxic, safe, and serves as an important source of natural antioxidants. In addition, the fruit extract has the potential to ameliorate hepato- and nephrotoxicities and cardiovascular diseases as well as iron deficiency anemia.

Abstract
Varthemia iphionoides is a Jordanian medicinal plant with several health-promoting properties, including antibacterial, antioxidant and anticancer activities. However, its anti-inflammatory properties have been poorly investigated up to date. The current study aimed to investigate the anti-inflammatory effect of V. iphionoides by measuring the production of interleukin-6 in response to a pro-inflammatory stimulus (bacterial lipopolysaccharide) in in vitro cell models of human MRC-5 and PC3 cells. We observed a significant reduction in lipopolysaccharide-induced interleukin-6 release in response to V. iphionoides (125 µg/mL) in both non-cancerous fibroblast MRC-5 and prostate cancerous PC3 cells. However, the anti-inflammatory effect of this medicinal plant was stronger when MRC-5 cells were treated with an aqueous extract, while the methanolic extract was more potent in PC3 cells. The effect of V. iphionoides in reducing interleukin-6 production was not due to its cytotoxicity, and future studies are required to elucidate the mechanisms of action by which this medicinal plant modulates inflammatory responses. In conclusion, the results of our study represent the first report of the potential protective effect of water and methanolic extracts of V. iphionoides against pro-inflammatory stimuli in fibroblasts and cancer cells of human origin, and it is critically important to identify the phytochemical compounds responsible for this effect.

Abstract
BACKGROUND Medicinal plants are an important source of substances which are claimed to induce antimicrobial, antimutagenic and antioxidant effects. Many plants have been used due to their antimicrobial treatments. Antimicrobial and antioxidant activities of L. orientalis have not been reported to the present day. The aim of this work was to investigate of the antimicrobial and antioxidant potentials of different extracts from L. orientalis. MATERIALS AND METHODS The extracts were screened for antimicrobial activity against different food pathogens. These bacteria include 4 Gram positive and 3 Gram negative bacteria and one fungi. The leaf extracts of plant were tested by disc diffusion assay. The MIC was evaluated on plant extracts as antimicrobial activity. In addition to, the plant extracts were tested against the stable DPPH (2,2-diphenyl-1-picryl-hydrazylhydrate) free-radical. RESULTS The acetone, ethanol and methanol extracts of L. orientalis showed maximum inhibition zone of 12 mm against Yersinia enterocolitica, Listeria monocytogenes and Staphylococcus aureus. In addition to, the methanol extract displayed a strong antioxidant activity (trolox equivalent = 2.23 mM). CONCLUSION L. orientalis extracts have antimicrobial, and antioxidant potential. Our results support the use of this plant in traditional medicine and suggest that some of the plant extracts possess compounds with good antibacterial properties that can be used as antibacterial agents in the search for new drugs.

Abstract
Plant species have long been regarded as possessing the principal ingredients used in widely disseminated ethnomedical practices. Different surveys showed that medicinal plant species used by the inhabitants of Jordan for the traditional treatment of diabetes are inadequately screened for their therapeutic/preventive potential and phytochemical findings. In this review, traditional herbal medicine pursued indigenously with its methods of preparation and its active constituents are listed. Studies of random screening for selective antidiabetic bioactivity and plausible mechanisms of action of local species, domesticated greens, or wild plants are briefly discussed. Recommended future directives incurring the design and conduct of comprehensive trials are pointed out to validate the usefulness of these active plants or bioactive secondary metabolites either alone or in combination with existing conventional therapies.

Abstract
The ever-increasing emergence of the resistance of mammalian tumor cells to chemotherapy and its severe side effects reduces the clinical efficacy of a large variety of anticancer agents that are currently in use. Thus, despite the significant progress in cancer therapeutics in the last decades, the need to discover and to develop new, alternative, or synergistic anticancer agents remains. Cancer prevention or chemotherapy based on bioactive fractions or pure components derived from desert plants with known cancer-inhibiting properties suggests promising alternatives to current cancer therapy. Plants growing on low nutrient soils and/or under harsh climatic conditions, such as extreme temperatures, intense solar radiation, and water scarcity, are particularly susceptible to attack from reactive oxygen species and have evolved efficient antioxidation defense systems. The many examples of desert plants displaying anticancer effects as presented here indicates that the same defensive secondary metabolites protecting them against the harsh environment may also play a protective or a curative role against cancer, as they also do against diabetes, neurodegenerative, and other acute and chronic diseases. The present review highlights a plethora of studies focused on the antineoplastic properties of desert plants and their prinicipal phytochemicals, such as saponins, flavonoids, tannins, and terpenes. Although many desert plants have been investigated for their antitumor properties, there are many that still remain to be explored - a challenge for the prospective cancer therapy of the future.

Abstract
CONTEXT Phytochemicals are produced by desert plants to protect themselves against stressful environments. They have been shown to be useful in preventing and fighting adverse pathophysiological conditions and complex diseases, including cancer. Although many desert plants have been investigated for their antitumor properties, a large number of them still remain to be explored for possible therapeutic applications in oncologic diseases. OBJECTIVE To screen the antitumor effects of selected desert plants, namely Achillea fragrantissima (Forssk.) Sch. Bip. (Compositae), Ochradenus baccatus Delile (Resedaceae), Origanum dayi Post (Lamiaceae), Phlomis platystegia Post (Lamiaceae) and Varthemia iphionoides Boiss (Compositae), against an in vitro tumor model utilizing HepG2 human hepatocellular carcinoma cells. MATERIALS AND METHODS The aqueous extracts of aerial parts of the aforementioned plants were prepared and used for the in vitro experiments. The HepG2 cells were exposed to varying concentrations (0-4 mg/mL) of each plant extract for 24 or 48 h and the cytotoxicity was measured by the MTT assay. RESULTS Following 24 h exposure, O. dayi extract exhibited a substantial antiproliferative effect in HepG2 cells (IC50 = 1.0 mg/mL) followed by O. baccatus (IC50 = 1.5 mg/mL). All plant extracts displayed cytotoxicity following 48 h exposure. Nevertheless, a substantial effect was observed with O. dayi (IC50 = 0.35 mg/mL) or O. baccatus (IC50 = 0.83 mg/mL). CONCLUSION The aqueous extracts from aerial parts of O. dayi and O. baccatus possess antitumor effects against human liver cancer cells. These desert plants represent valuable resources for the development of potential anticancer agents.

Abstract
CONTEXT Eryngium creticum Lam. (Umbelliferae), Geranium graveolens L.Her.exn Ait (Geraniaceae), Paronychia argentea Lam. (Caryophyllaceae), and Varthemia iphionoides Boiss (Compositae) have traditionally been used as antidiabetic phytomedicines. However, their alleged benefits and mechanisms remain elusive. OBJECTIVES To evaluate the effect of these plants on in vitro and in vivo enzymatic starch digestion. MATERIALS AND METHODS In vitro enzymatic starch digestion with acarbose or (1-50 or 100 mg/ml) plants aqueous extracts was assayed using α-amylase and α-amyloglucosidase. Oral starch tolerance tests and oral glucose tolerance tests were determined for the plant extracts at concentrations 125, 250, and 500 mg/kg body weight. Blood glucose levels in rats treated with plant extracts or drugs (acarbose or metformin and glipizide) were measured at -30, 0, 45, 90, and 135 min. RESULTS AND DISCUSSION In vitro, acarbose, and water extracts of G. graveolens and V. iphionoides exerted significant dose-dependent dual inhibition of α-amylase and α-glucosidase, with respective IC₅₀s of 1.2 μg/ml, 84.7, and 65.2 mg/ml. Comparable in vivo acute postprandial antihyperglycemic efficacies were obtained for G. graveolens and V. iphionoides in starch-fed rats. E. creticum exhibited substantial acute antihyperglycemic activities in starch-treated rats, despite lacking any favorable in vitro effectiveness. However, P. argentea lacked any inhibitory efficacy. None of the plant extracts qualified for improving the glucose tolerance in fasted rats on glucose loading. CONCLUSION G. graveolens and V. iphionoides can be considered as potential candidates for therapeutic modulation of impaired fasting glycemia, impaired glucose tolerance, and type 2 diabetes.

Abstract
Several species of Senna are well known for their therapeutic properties, being used in folk medicine to treat throat inflammation and constipation. In this regard, the anti-inflammatory, laxative and intestinal motility effects of different extracts of Senna macranthera (Colladon) H. Irwin and Barneby leaves were determined. The hexane extract significantly reduced carrageenan-induced paw oedema in rats in a manner similar to that of sodium diclofenac. A laxative effect was observed for the methanolic and hexane extracts comparative to the standard drug bisacodyl; however, only the hexane extract increased the intestinal motility in the studied period. Moreover, the extracts were evaluated for their antioxidant activity and the ethyl acetate extract presented a pronounced activity comparable to the standard rutin. Phytochemical screening was also performed and phenolic compounds like flavonoids, tannins and coumarins were observed in all extracts except for the hexane extract, which instead presented anthrones, triterpenes and steroids in its composition. The HPLC profile showed the presence of the anthraquinone emodine in all tested extracts.

Abstract
Pouzolzia zeylanica was extracted with different solvents (acetone, ethyl
acetate and petroleum ether), using different protocols (cold-extraction and
Soxhlet extraction). To evaluate the antiradical and antioxidant abilities of
the extracts, four in vitro test systems were employed, i.e., DPPH, ABTS and
hydroxyl radical scavenging assays and a reducing power assay. All extracts
exhibited outstanding antioxidant activities that were superior to that of
butylated hydroxytoluene. The ethyl acetate extracts exhibited the most
significant antioxidant activities, and cold-extraction under stirring seemed
to be the more efficacious method for acquiring the predominant antioxidants.
Furthermore, the antioxidant activities and total phenolic (TP) content of
different extracts followed the same order, i.e., there is a good correlation
between antioxidant activities and TP content. The results showed that these
extracts, especially the ethyl acetate extracts, could be considered as
natural antioxidants and may be useful for curing diseases arising from
oxidative deterioration.

Optimal methods for evaluating antimicrobial activities from plant extracts. J Microbiol Methods 2010; 84:161-6. [PMID: 21094190 DOI: 10.1016/j.mimet.2010.11.008] [Citation(s) in RCA: 64] [Impact Index Per Article: 4.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2010] [Revised: 10/22/2010] [Accepted: 11/02/2010] [Indexed: 11/24/2022]
Abstract
The search for antimicrobial agents from plants has been a growing interest in the last few decades. However, results generated from many of these studies cannot be directly compared due to the absence of standardization in particular antimicrobial methods employed. The need for established methods with consistent results for the evaluation of antimicrobial activities from plant extracts has been proposed by many researchers. Nevertheless, there are still many studies reported in the literature describing different methodologies. The aim of this study was to find optimal methods to give consistent quantitative antimicrobial results for studying plant extracts. Three different agar-based assays (pour plate disc diffusion (PPDD), streak plate disc diffusion (SPDD) and well-in agar (WA)) and one broth-based (turbidometric (TB)) assay were used in this study. Extracts from two plant species (Duabanga grandiflora and Acalypha wilkesiana) were tested on two bacterial species, namely Escherichia coli and Staphylococcus aureus. Amongst the agar-based assays, PPDD produced the most reproducible results. TB was able to show the inhibitory effects of the test samples on the growth kinetic of the bacteria including plant extracts with low polarity. We propose that both agar- (i.e PPDD) and broth-based assays should be employed when assessing the antimicrobial activity of plant crude extracts.

Abstract
The Euonymus alatus (Thunb.) Sieb. has long been used as a crude drug. In this paper, we investigate the effects of E. alatus on cultured hepatocyte cell system and lipid peroxidation in hydrogen peroxide (H(2)O(2)) treatment conditions. The study covers the physiological activity (the antioxidative activity and the nitrite-scavenging effect) of E. alatus. H(2)O(2) that can produce intracellular free radical was used for inducer of the peroxidation of cellular lipids. Treatment of E. alatus attenuated in cell killing enhanced by increasing concentrations of H(2)O(2). The increased malondialdehyde level induced by H(2)O(2) treatment was reduced by pre-treatment of E. alatus. Furthermore, addition of E. alatus in cell culture medium significantly reduced cell killing and content of intracellular antioxidants. Changes in nitrite-scavenging effect of E. alatus at various concentrations (5-25 mg/ml) and various pH levels (pH 1.2, 4.2 and 6.0) were also observed. The present study was also done to investigate the effects of E. alatus on cultured hepatocyte cell system, H(2)O(2)-induced cytotoxicity and antioxidative enzyme activities, including catalase, superoxide dismutase, glutathione peroxidase and glutathione S-transferase in H(2)O(2 )treatment conditions. E. alatus treatment had significant protective or elevating activities on these antioxidative enzyme activities compared to a normal group. The results indicate that E. alatus provides a strong antioxidant protection of cells against H(2)O(2)-induced oxidative stress.

Abstract
A pronounced antiproliferative effect on human leukemia K562 cells was shown with flavonoid-enriched extracts from Rhamnus alaternus roots and leaves, with, respectively, IC(50) values of 165 and 210.73 microg/mL. High DPPH radical-scavenging activity (7.21 and 18.84 microg/mL, respectively) and antioxidative effects using the xanthine oxidase assay (IC(50) values of 83.33 and 103.96 microg/mL, respectively) were detected in the presence of the two tested extracts. Although no mutagenic effect was observed when using the Salmonella typhimurium assay system with TA1535 and TA100 strains, the two tested extracts exhibited a high-level protection toward the direct mutagen, sodium azide-induced response.

Abstract
The aerial parts of the endemic plant of Otostegia persica Boiss. in two different stages of flowering and fruiting were hydro-distilled to extract oils in the yields of 0.3 and 0.15% (v/w), respectively. The oils were analyzed by GC and GC/MS. Twenty-eight and thirty-one components were identified, representing 97.59 and 94.61% of the oils, respectively. The main compounds of the essential oil flowers (EOFL) were alpha-pinene (17.21%), 1-octen,3-ol (13.44%) and cubenol (7.27%), whereas diisooctyl phthalate (45%) and hexadecanoic acid (11.07%) were the major constituents of the essential oil of the fruits (EOFR). The oils were screened for their possible antioxidant activities by two complementary test systems, namely DPPH free radical-scavenging and ammonium thiocyanate. In both tested systems, EOFL exerted greater antioxidant and radical scavenging activity. In the first case, EOFL exerted antioxidant activity with an IC50 19.8 +/- 1.8 microg mL(-1) almost similar to BHA and ascorbic acid (15.2 +/- 1.1 and 17.4 +/- 1.3), respectively. In the ammonium thiocyanate system, the inhibition rate of oxidation of linoleic acid for EOFL was estimated 93.5 +/- 2.8. The higher activity of this oil in comparison to EOFR may be attributed to its high content of monoterpenes, especially oxygenated ones in the oil of the flowers.
