TL;DR: The chemical composition of essential oils obtained from the leaves of Pistacia vera, Pistacia terebinthus, Pistacia lentiscus and the resin of Pistacias lentiscUS were analyzed and alpha-Pinene, beta-pinene, limonene, terpinen-4-ol andalpha-terpineol were found to be the major components of antifungal activities.

TL;DR: The aqueous extract showed significant antimicrobial activity, which may be due to the combined effect of the isolated arabinogalactan proteins and andrographolides.

TL;DR: Nine flavonoids (1-9) have been isolated from Kaempferia parviflora and none of the isolated compounds demonstrated cytotoxicity against KB, BC and NCI-H187 cell lines.

TL;DR: The antioxidant properties of six medical herbs used in the traditional Paraguayan medicine were studied using free radical-generating systems and methanol extracts from Aristolochia giberti, Cecropia pachystachya, Eugenia uniflora, Piper fulvescens, Schinus weinmannifolia and Schinus terebinthifolia protected against enzymatic and non-enzymatic lipid peroxidation in microsomal membranes of rat.

TL;DR: Analysis of the medical uses of 300 Chinese medical woody plants showed that most of them are employed for their effects on hemostasis, as anti-inflammatory, antimicrobial or for treatment of dysentery.

TL;DR: The results indicate that nettle has a significant antihyperglycemic effect in OGTT model, which may be caused in part by the reduction of intestinal glucose absorption.

TL;DR: The essential oil of Rosa damascena petals was evaluated for its antibacterial effects against three strains of Xanthomonas axonopodis spp.

TL;DR: The oral treatment with the aqueous extract of Momordica cymbalaria fruit for 6 weeks showed a significant antihyperglycemic as well as antihyperlipidemic effects in the alloxan-induced diabetic rats.

TL;DR: In this article, the authors used the leaves, barks, and roots of 50 plant species used in the traditional medicine of Perak, Peninsular Malaysia, have been screened for antibacterial and antifungal activities.

TL;DR: In this paper, for the first time pharmacobotanical properties are systematically emphasised for the folk food species of Central Italy.

TL;DR: The relaxant effect of the essential oil of Melissa officinalis and its main component, citral, on rat isolated ileum contractions was evaluated and inhibited the response to KCl, ACh and 5-HT in a concentration-dependent manner.

TL;DR: The crude extracts of the leaves of Dodonaea viscosa and Rumex nervosus as well as of the root of Rumex abyssinicus were tested for anti-microbial and anti-inflammatory activities and it was observed that the three plants possess antibacterial activity against Streptococcus pyogenes and Staphylococcus aureus and strong activity against Coxsackie virus B3 and influenza A virus.

TL;DR: A HPLC method for the determination of withaferin A and withanolide D was developed and was successfully used to investigate the presence of the markers in different W. somnifera plant parts as well as to analyze their content in market products.

TL;DR: The data suggest that piperine may extend its chemopreventive effect by modulating lipid peroxidation and augmenting antioxidant defense system.

TL;DR: The essential oils of Xylopia aethiopica, Monodora myristica, Zanthoxylum xanthoxyloïdes and Z. leprieurii, four Cameroonian plants used as spices in local food, showed antibacterial and antifungal activity.

TL;DR: Clitoria ternatea roots methanol extract when given by oral route to rats was found to inhibit both the rat paw oedema caused by carrageenin and vascular permeability induced by acetic acid in rats.

TL;DR: During the work-up of the faradiol esters, accompanying minor compounds of the triterpene ester fraction were purified and identified by spectroscopic means as maniladiol 3-O-laurate and myristate.

TL;DR: The results of a preliminary antimicrobial screening of the methanol extracts of Aframomum melegueta, Piper guineense, Xylopia aethiopica, Zingiber officinale, medicinal plants of Ghana, are reported.

TL;DR: The crude extracts obtained from the leaves of Pistacia vera, Pistacia terebinthus and Pistacia lentiscus were tested for antifungal activities against three pathogenic agricultural fungi, Phythium ultimum, Rhizoctania solani and Fusarium sambucinum.

TL;DR: The antimicrobial activity of Berberis heterophylla leaves, stems and root aqueous extracts was studied in vitro on Gram-positive and Gram-negative bacteria and fungi.

TL;DR: Oral treatment with 50 mg X kg(-1) day (-1) of crude methanol extract of Centella asiatica for 14 days significantly increased the anti-oxidant enzymes, like superoxide dismutase (SOD), catalase and glutathione peroxidase (GSHPx), and anti-Oxidant substances decreased in lymphoma-bearing mice.

TL;DR: ESR spectroscopy demonstrated that glabridin neither produced radical, nor affected the radical intensity of sodium ascorbate, suggesting the lack of correlation between the antinephritis activity and radical scavenging activity.

TL;DR: Antiviral properties of betulin, betulinic and betulonic acids were investigated in cell cultures infected with herpes simplex type I, influenza FPV/Rostock and ECHO 6 viruses.

TL;DR: Embelin, a benzoquinone-derivative isolated from Embelia ribes, when tested for its antibacterial potential exhibited significant inhibition against five and moderate activity against three strains of the 12 bacteria tested.

TL;DR: Methylene chloride and methanol extracts of 20 Indonesian plants with ethnomedical uses have been assessed for in vitro antibacterial and antifungal properties by disk diffusion method as discussed by the authors.

TL;DR: The crude methanolic extracts of the stem androot barks, stem and root heart-wood, leaves, fruits and seeds of Artocarpus heterophyllus and their subsequent partitioning with petrol, dichloromethane, ethyl acetate and butanol gave fractions that exhibited a broad spectrum of antibacterial activity.

TL;DR: The ethanolic extracts of the leaves and seeds of Bixa orellana showed a broad spectrum of antimicrobial activity and the activity of the leaf extract was more pronounced.
