Preliminary phytochemical screening showed the presence of terpenes, flavonoids, tannins, alkaloids, phenolic acid, sterols, and glycosides. This study was intended to evaluate the antiinflammatory activity of various extracts of fresh leaves of Clerodendrum paniculatum Linn experimentally by in vitro (human red blood cell membrane stabilization method) and in vivo methods (0.1 ml of 1% w/v car...

Serial extracts of the seeds of M.fragrans were investigated for their anti-diarrhoeal potential in three experimental models. Though all the three extracts exhibited significant activity, the petroleum ether and ethanol extracts were found to be more effective above 200 mg | kg dose levels.

The aim of this study was to investigate in vitro antioxidant, anticholinesterase and antibacterial activities of the petroleum ether, chloroform and methanol extracts obtained from the aerial parts of Jurinea consanguinea DC. (Asteraceae). Total phenolic and flavonoid contents of these crude extracts were determined as pyrocatechol and quercetin equivalents, respectively. The methanol extract ...

Antimicrobial activities of methanolic and petroleum ether extracts of Croccus sativus L. (saffron) stigmas, were tested against various bacterial strains (Proteus vulgaris, Klebsiella pneumonia, Pseudomonas aeruginosa, Staphylococcus aureus and Escherichia coli) and fungi (Candida albicans, Aspergillus niger and Aspergillus fumigatus) by agar well diffusion method. Minimal inhibitory concentra...

The whole plant, Pergularia daemia (Family: Asclepediaceae), was extracted with 50% alcohol and a fresh batch of the plant material was successively extracted with petroleum ether, ethyl acetate and n-butanol to determine its diuretic activity. The diuretic activity of the different extracts at a dose of 400 mg/Kg was assessed orally in rats with furosemide as a standard drug using Lipschitzs t...

Composted and fresh beef cattle manure samples were extracted with distilled water, acetone, methanol, 2 N sodium hydroxide, 2 N hydrochloric acid, and ether. Bioassay techniques, using the extracts, showed that composted manure extracts had limited effect on seed germination and seeding development of wheat and sorghum. All the extracts of fresh manure, other than distilled water, retarded ger...

High-speed counter-current chromatography (HSCCC) was successfully applied to the preparative separation and purification of deoxyschisandrin and gamma-schisandrin from the crude petroleum ether extracts of Schisandra chinensis (Turcz.) Baill. The optimum solvent system composed of n-hexane-methanol-water (35:30:3, v/v) led to the successful preparation of deoxyschisandrin and gamma-schisandrin...

Leptadenia reticulata of Asclepidaceae family is a shrub, originally property of Petroleum ether, Alcohol & Chloroform extract of L. reticulata. The antimicrobial testing was carried out by "Disc diffusion method". Amongst the tested three extracts, chloroform extract showed high antimicrobial activity against E. coli, alcoholic extract showed high antibacterial activity against Pseudomonas aer...

Currently, research on the bambangan-fruit seed has become interesting because of its potential application as a cocoa butter alternative. This work aimed to determine changes in quality extracted bambangan-seed fat (BSF) obtained using hexane, petroleum ether, and ethanol. The extraction solvents affected total content (TFC), physicochemical properties, fatty-acid profile, triacylglycerol comp...

Antioxidant effects of the Petroleum ether extracts of the leaves of Calotrois procera were tested on the basis of scavenging activity of the free radical DPPH (1, 1-diphenyl2-picryl-hydrazyl), reducing power and inhibition of nitric oxide radical . The Petroleum Ether extracts of C .procera showed the highest antioxidant activity and the activity of the extract increased with increasing concen...
