TL;DR: Two catabolic enzymes responded differentially in fungi and bacteria against sublethal concentrations of the compound when assayed from their cell free extracts, indicating a possible different mechanism of inhibition of saponins on the organisms tested.

TL;DR: The anticonvulsant activities of Crocus sativus stigma constituents, safranal and crocin, were evaluated in mice using pentylenetetrazole (PTZ)-induced convulsions in mice and reduced the seizure duration, delayed the onset of tonic Convulsions and protected mice from death.

TL;DR: The results demonstrate a significant, dose-dependent effect of water extracts of I. paraguensis on AGE adducts formation on a protein model in vitro, whereas green tea displays no significant effect.

TL;DR: The insecticidal activities of extracts and oils of seventeen medicinal plants of Brazil have been determined using an Aedes aegypti larvicidal bioassay and the potential application of cashew nut oil, an industrial by-product with low commercial value, in the control of the vector of dengue and yellow fever may be proposed.

TL;DR: Results of this study suggest the possible chemopreventive effects of embelin (EMB) and curcumin (CUR) against DENA/PB-induced hepatocarcinogenesis in Wistar rats.

TL;DR: An ethnobotanical and ethnopharmacognostic survey has been carried out in one of the most isolated mountainous area in Europe: the village of Lepushe and its surrounding territory, in the Northern Albanian Alps, and a current common ethnomedical use of P. scolopendrium and L. martagon is recorded for the first time in Europe.

TL;DR: The antifungal activity of Eugenia cariophyllata essential oil and eugenol, its major constituent, on fungal strains isolated from onychomycosis was evaluated.

TL;DR: The antibacterial and antifungal activities of pinosylvin, a constituent of pine, were studied and compared with those of resveratrol.

TL;DR: From the capitula of Helichrysum compactum, the flavonoids apigenin, kaempferol, luteolin, naringenin, 3,5-dihydroxy-6,7,8-trimethoxyflavone, and quercetin-3-O-glucoside were isolated as discussed by the authors.

TL;DR: The antifungal effects of rosemary, cumin, sater (savory), basil and pickling herb hydrosols were investigated against Rhizoctonia solani, Fusarium oxysporum f.

TL;DR: The diterpenoids 16alpha-hydroxy-cleroda-3,13 (14)-Z-diene-15,16-olide and 16-oxo-clerodic acid, isolated from the hexane extract of the seeds of Polyalthia longifolia, demonstrated significant antibacterial and antifungal activities.

TL;DR: The ethanolic extracts of Curcuma longa and Alpinia galanga exhibited excellent phytotoxic activity against Lemma minor, and these extracts were found quite inert in antibacterial bioassay, while the extract from C. longa, tested for insecticidal activity, was also found to be devoid of any activity.

TL;DR: Findings suggest that M. alba leaf extract seems to be able in suppressing inflammatory mediators and the inhibitory activities on COX-2 and iNOS of its butanol fraction are warranted for further elucidation of active principles for development of new antiinflammatory agents.

TL;DR: Fractions rich in flavonoids obtained from the fruits of Punica granatum extract, orally administered to rats at dose of 10 mg kg(-1) day(-1), showed potential antiperoxidative effect.

TL;DR: The results of a preliminary antifungal screening of the methanol extracts and the major anthraquinone aglycones, alizarin and emodin, of Rubia tinctorum and Rhamnus frangula in comparison with the antIFungal activity of the anthraquone-containing lichen Caloplaca cerina and its main secondary metabolite parietin are reported.

TL;DR: The HPLC-UV method was proven to be sensitive, specific, accurate and precise, as well as effective and easy.

TL;DR: The antiviral activity of six medicinal plants from Brazilian Atlantic Tropical Forest was investigated against two viruses and corroborate that medicinal plants can be a rich source of potential antiviral compounds.

TL;DR: The methanol, petroleum ether, ethyl acetate and water-methanol extracts of Ruta graveolens were found to possess antimicrobial and cytotoxic activities.

TL;DR: The results showed that the extract produced significant vasorelaxation and that the effect is dependent on the synthesis or release of endothelium-derived relaxing factors (EDRFs) as well as the release of prostanoid.

TL;DR: The hydroalcoholic extract of Equisetum arvense (HAE) tested at the doses of 200 and 400 mg/kg showed a significant activity on the open-field, enhanced the number of falls in the rota-rod reducing the time of permanence in the bar and increased the sleeping time in theBarbiturate-induced sleeping time.

TL;DR: Although the methanol extract of P. furfuracea had the highest total phenolic contents, it exhibited low antioxidant activity, and there was a strong correlation between reducing power and total antioxidant activity of the extracts.

TL;DR: The essential oil obtained by hydrodistillation of the resin of Canarium schweinfurthii growing in Central African Republic shows a significant analgesic effect using acetic acid-induced writhing and hot plate methods, but was unable to reduce inflammatory process in cotton pellet induced granuloma method.

TL;DR: A survey of medicinal plants used by the ethnic communities of Dibru-Saikhowa Biosphere Reserve in Northeast India has been reported and plant species belonging to 34 families and 52 different genera were included.

TL;DR: Twenty-five extracts obtained from 14 plant species used in the traditional medicine in Yemen have been screened for cytotoxic activity against human ECV-304 cells and Dracaena cinnabari, Eucalyptus camaldulensis, Euclea divinorum, Euphorbia cactus, Pulicaria crispa, and Withania somnifera displayed a remarkable activity.

TL;DR: Lythrum salicaria extracts showedActivity against the phytopathogenic fungus Cladosporium cucumerinum and activity against the bacteria Staphylococcus aureus, Proteus mirabilis and Microccocus luteus.

TL;DR: In this article, a bioassay-guided fractionation of Lychnophora pohlii extracts yielded seven active compounds: the sesquiterpene lactones lychnopholide, centratherin, goyazensolide and 15-desoxygoyazensolside in the dichloromethane extract, and caffeic acid and the flavonoids luteolin and vicenin-2 in the methanol extract.

TL;DR: The saline leaf extract of Bryophyllum pinnatum was investigated on neuropharmacological activities to ascertain claims of local use and produced a dose-dependent prolongation of onset and duration of pentobarbitone-induced hypnosis, reduction of exploratory activities in the head-dip and evasion tests.
