euphorbia wallichii a perennial herb growing mainly in himalayas has been widely used in folk medicines for its medicinal properties. in the present study, the crude methanolic root extract (cme) and its fractions; n-hexane fraction (nhf), n-butanol fraction (nbf), chloroform fraction (chf), ethyl acetate fraction (eaf) and aqueous fraction (aqf) of this plant specie were investigated for antio...

In mice, active protection against Pseudomonas aeruginosa could be induced with two fractions derived from a crude preparation of ribosomes from P. aeruginosa. The two fractions were obtained by gel filtration chromatography of the crude ribosomal preparation on Sepharose CL-2B. In fraction I, less than 1% of the ribonucleic acid (RNA) applied to the column was recovered. Fraction II contained ...

We investigated the antiplasmodial properties of crude extracts from Carica papaya leaves to trace the activity through bioassay-guided fractionation. The greatest antiplasmodial activity was observed in the ethyl acetate crude extract. C. papaya showed a high selectivity for P. falciparum against CHO cells with a selectivity index of 249.25 and 185.37 in the chloroquine-sensitive D10 and chlor...

The aim of the present study was to explore the aerial parts of the Polygonatum verticillatum for various biological activities such as phytotoxic, insecticidal and leishmanicidal properties. Outstanding phytotoxicity was observed for the crude extract and its subsequent solvent fractions against Lemna acquinoctialis Welv at tested doses of 5, 50 and 500 μg/ml. Complete growth inhibition (100%)...

the crude methanolic extract of the seeds of celastrus paniculatus along with its organic soluble fractions were tested for their possible antioxidant and anti-alzheirmer (ad) activity. the extracts showed prominent dpph free radical scavenging activity, inhibiting activity of authentic peroxynitrite (onoo-) and inhibition of total reactive oxygen species (ros) generation. in dpph radical scave...

The antioxidant potential of crude methanol extract (CE) as well as chloroform (CF), ethyl acetate (EF) and n-butanol (NF) soluble fractions of Enhydra fluctuans Lour, which is widely used in indigenous system of medicine for different purposes, were studied. The antioxidant potential of extract/different fractions were evaluated using different in vitro antioxidant models. In addition, total a...

A crude rat liver mitochondrial fraction that was capable of the rapid, linked synthesis of phosphatidylserine (PtdSer), phosphatidylethanolamine (PtdEtn), and phosphatidylcholine (PtdCho) labeled from [3-3H] serine has been fractionated. PtdSer synthase, PtdEtn methyltransferase, and CDP-choline:diacylglycerol cholinephosphotransferase activities were present in the crude mitochondrial prepara...
