Screening of different extracts and fractions from the plant Bidens pilosa Linn. var. (Asteraceae) has been conducted using the in-vitro comet assay for anticancer and the antipyretic action, which was done with in-vivo models. The extract from whole plant was extracted with n-hexane, chloroform and methanol extract (E1 - E3). The extracts were fractioned by column chromatography method and fra...

The purpose of this study was to evaluate the antioxidant and anticholinesterase activities of yellow and white bitter yams from South Western Nigeria using methanolic extraction and simulated gastrointestinal digestion models. The phenolic compounds in the bitter yam varieties were evaluated by high performance liquid chromatography with a diode array detector (HPLC-DAD). The total phenolic co...

the therapeutic potential of crude extracts of aerial parts (stem, leaves and flowers) of tridax procumbens was screened for in vitro antioxidant potential and alpha amylase inhibitory action. the crude hydro-methanolic, aqueous and petroleum ether extracts were obtained by percolation-maceration method using 50% methanol, double distilled water and petroleum ether as solvents. phytochemical sc...

three extracts of pulicaria dysenterica were examined for antibacterial activity using the agar disk-diffusion method against six bacterial strains. some of these extracts were found to be active against some bacterial strains. the methanolic extract exhibited a superior level of antibacterial activity. all of the extracts were active against vibrio chlorea.

Natural plant extracts / products have the potential as safe alternatives for chemical fungicides in plant disease management. Methanol and pure methanol: water (50:50 v/v) extracts of peppermint, lavandula, eucalyptus, datura and nettle were screened for their antifungal activity against Alternaria sesami, the causal agent of Alternaria leaf spot of sesame at 5, 10 and 15% concentrations in Sh...

PURPOSE The aim of this study was to investigate in vitro cytotoxic activity of four methanolic crude plant extracts against panel cell lines. METHODS Methanolic extracts were tested for their possible antitumor activity and cytotoxicity using the 3-(4,5-dimetylthiazol-2-yl)-2,5- diphenyltetrazolium bromide (MTT) assay on six cancer cell lines; non-Hodgkin's B-cell lymphoma (Raji), human leuk...

Epilepsy is a neurological disorder characterized by unprovoked, recurring seizures that disrupts the nervous system and can cause mental and physical dysfunction. Based on the ethno pharmacological information of the plant, the methanolic and aqueous extracts of the flowers of Nepeta bractaeta was evaluated for its antiepileptic activity. The methanolic and aqueous extracts of the flowers of N...

The Anthelmintic activities of methanolic and aqueous extracts of stems of Achyranthes aspera linn. were evaluated separately on Indian adult earthworms Pheretima posthuma (Annelida). For this work the stems were extracted separately with methanol and distilled water by following maceration method. Various concentrations (2.5, 5, 10, 20 mg/ml) of each extract were tested for anthelmintic activi...
