The study was intended to explore the antioxidant potential and phytochemical content of the ethanol and aqueous extracts of the leaf and root samples of Cissus cornifolia (Baker) Splanch (Vitaceae) across a series of four in vitro models. The results showed that all the extracts had reducing power (Fe(3+) - Fe2+) and DPPH, hydroxyl and nitric oxide radical scavenging abilities to varying exten...

Aqueous suspension of ethanol extracts of Derris (Lonchocarpus) urucu (Leguminosae), collected in the state of Amazonas, Brazil, were tested for larvicidal activity against the mosquito Aedes aegypti (Diptera:Culicidae). The aim of this study was to observe the alterations of peritrophic matrix in Ae. aegypti larvae treated with an aqueous suspension of D. urucu extract. Different concentration...

Aqueous extract of Moringa oleifera Lam. (root) has been studies on pre and post-implementation stages of the uterus of rats so as to elucidate its antifertility mode of action. Results on the biochemical estimation in the uterus of control pregnant rats at different stages of pregnancy revealed a successive increase in the total proteins, glycogen content and the activity or acid and alkaline ...

308 ABSTRACT: Aqueous root extract of Albizzia chevalieri has been reported to possess hypoglycaemic and hypolipidaemic effects. The current work investigated the LD50 of the crude aqueous root extract of Albizzia chevalieri and the effect of sub-chronic doses of the extract on liver and kidney function parameters of albino rats. The results indicated LD50 greater than 3000mg/kg body weight in ...

in order to evaluate the allelopathic potential of sunflower (helianthus annus l.) organs on germination and growth of dodder (cuscuta compestris l.), series studies were conducted in three separate experiments; as factorial based on completely randomized design (crd) with three replications for each experiments. first experiment was conducted in petri dishes and consisted of sunflower organs a...

Purpose: To evaluate the efficacy of aqueous root extract of Lecaniodiscus cupanioidies Planch. (Sapindaceae) against loperamide-induced constipation in Wistar rats. Methods: Constipation was induced by oral administration of loperamide (3 mg/kg body weight). The constipated rats were orally treated daily either with 50, 150, 250 mg/kg body weight per day of the extract or 0.21 mg/kg bisacodyl ...

licorice (glycyrrhiza glabra l.) is an important medicinal plant. in this study, the antimicrobial activities of ethanolic and aqueous extracts from licorice leaves were studied compared to root extracts activities. bacillus subtilis, enterococcus faecalis, klebsiella pneumoniae, pseudomonas aeruginosa, staphylococcus aureus and escherichia coli, and candida albicans were used as test organisms...

Two lignan sulfates, a stilbene derivative and a phenol sulfate, together with 10 known compounds, were isolated from an aqueous extract of the root of Polygonum cuspidatum. The new compounds were elucidated based on chemical evidence and spectroscopic techniques including two-dimensional NMR methods. They exhibited no inhibition of lipid peroxidation and no cytotoxic and DNA cleavage activities.

Treatment with 100 mg/kg of Clitoria ternatea aqueous root extract (CTR), for 30 days in neonatal and young adult age groups of rat, significantly increased acetylcholine (ACh) content in their hippocampi as compared to age matched controls. Increase in ACh content in their hippocampus may be the neurochemical basis for their improved learning and memory.

The aim of the present investigation was to determine the allelopathic effect of aqueous extract from either fresh or oven dried leaves and root of unstressed or water stressed maize plants on soybean growth and its effects on rhizosphere soil treated with maize plant extract. The extracts were applied for 10h to soybean [Glycine max (L.) Merr.] as seed soaking treatment prior to sowing. The ap...
