Plants continue to play a critical role in the discovery of effective compounds, especially anticancer drugs. Abutilon pannosum has been historically used as therapeutic plant medicinal system. In this study, an ethanolic crude extract was prepared from dried powder A. and subsequently fractionated produce chloroform, butanol, water fractions. The fractions were tested for their cytotoxic actio...

Reanmongkol, W., Subhadhirasakul, S. and Bouking, P. Antinociceptive and antipyretic activities of extracts and fractions from Dracaena loureiri in experimental animals Songklanakarin J. Sci. Technol., 2003, 25(4) : 467-476 Dried coarsely powdered material from the stem woods of Dracaena loureiri Gagnep (D loureiri) has extracted with hexane and methanol to give hexane and methanol extracts, re...

Capparis grandiflora was used to treat diarrhoea and other infective disorders in folklore. The present study aims at evaluating the action of chloroform soluble fraction, ethanol soluble fraction and ether soluble fraction of the leaves of Capparis grandiflora against inflammatory diseases. The anti-inflammatory effects were investigated by employing acute inflammatory model i.e.; carrageenan-...

Capillary electrophoretic profiling of hair fractions obtained by 0.25 M HCl treatment of the tissue with subsequent extraction of the solubilized fraction with chloroform-isopropanol (9:1, v/v) revealed clear differences between hair obtained from alopecia areata affected laboratory rats (both in hair obtained from non-affected areas and hair growing on once hairless patches) and controls. Dif...

The ethanolic extract of Aloe vera leaf skin was fractionated by liquid-liquid partition using hexane, ethyl acetate, chloroform-ethanol and butanol. The total phenolic content of the four different fractions were determined by Folin-Ciocalteu method and their antioxidant activity was essayed through some in vitro models such as the antioxidant capacity by phosphomolybdenum method, β-carotene b...

background and objectives: iran owns a rich and prestigious heritage of medicinal herbs but the majority of these plants have not yet undergone chemical, pharmacological and toxicological studies. in the present study some species form northern parts of iran were evaluated for cytotoxicity. methods: sixteen medicinal plants were extracted with methanol and screened for their cytotoxic activitie...

Lupeol (1), epilupeol (2) and β-sitosterol (3) were isolated from the n-hexane and the carbon tetrachloride soluble fraction of a methanol extract of the leaves of Phoenix paludosa Roxb. The n-hexane, carbon tetrachloride and chloroform soluble materials from the concentrated methanol extract were subjected to antimicrobial screening and brine shrimp lethality bioassay. All of the partitionates...

The aim of this work is to evaluate the antioxidant activity against the radical species DPPH, the reducing capacity against Fe II ions, and the inhibitory activity on the tyrosinase enzyme of the T. triangulare. Hydromethanolic crude extract provided two fractions after the liquid/liquid partition with chloroform. The Folin-Ciocalteu method determined the total phenolic content of the crude ex...
