The present study was carried out to evaluate the effect of methanol and chloroform extracts of Bauhinia purpurea on experimentally induced excision, incision, burn and dead space wound models in Sprague Dawley rats. Formulations of methanol and chloroform extracts of Bauhinia purpurea were prepared in carbopol and simple ointment base at concentrations of 2.5% and 5% and applied to the wounds....

The dermatophytes are filamentous fungi that cause cutaneous fungal infections because they use keratin as a nutrient source. For this study the antidermatophyte activity of the extracts and derivates from leaves of Piper regnellii was analyzed. From the dichloromethane extract (EBD) neolignans such as eupomatenoid-3 and eupomatenoid-5 were obtained, and it was submitted to fractionation to rem...

Present study evaluated in vitro antioxidant activity and cytotoxicity of four important Piper species (P. nigrum L., P. chaba Hunter, P. longum L. and P. colubrinum Link.) and six black pepper varieties (Sreekara, Subhakara, IISR Malabar Excel, Panniyur-1, Panchami and IISR Thevam). It was performed with sequential extracts of the dried berries/fruits using n-hexane, chloroform, methanol and w...

The present study was designed to evaluate the antioxidant activity of 5 organic solvent extracts (petroleum ether, n-hexane, chloroform, ethyl acetate and methanol) of wheat grains, 3, 5 and 7 days old wheat seedlings. To determine the antioxidant activity of five extracts of four different samples, 1,1-diphenyl-2-picrylhydrazyl and 2,2'-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid) radica...

background : within the framework to control mosquitoes, ovicidal, larvicidal and pupicidal activity of annona senegalensis leaf extract and its 4 fractions against anopheles gambiae and culex quinquefasciatus were evaluated in the laboratory conditions. methods : ovicidal test was performed by submitting at least 100 eggs of mosquitoes to 125, 250, 500, 1000 and 2000 ppm concentrations, while ...

Purpose: To investigate the anti-dyslipidemic, anti-oxidant and anti-diabetic activities of the aqueous extract and solvent fractions of A. violacea flowers. Methods: The aqueous extract was fractionated into petroleum ether, ether, chloroform, chloroformmethanol (4:1) and chloroform-methanol (3:2) fractions. Lipid lowering activity was evaluated in two models, viz, triton WR-1339 induced hyper...

Hexane, chloroform and aqueous extracts from Hemidesmus indicus and Ichnocarpus frutescens roots were evaluated for their antimicrobial activity. The chloroform extract of both plants showed antibacterial and antifungal activities against the tested organisms. Both the plants showed highest antibacterial and antifungal activity against Eschericia coli and Aspergillus flavus respectively. With i...

it has been reported that several members of convolvulaceae family such as convolvulus arvensis possess cytotoxic activity on some tumor cell lines. proteoglycan mixture, the water extract of c. arvensis with high molecular weight, has potent anti-angiogenesis and stimulating effects. in this study, arial parts of c. arvensis were collected and identified, and the cytotoxic effects of chlorofor...

Objectives: The present study was to study the phytochemical and antibacterial properties of Alternanthera brasiliana leaf extracts using three different solvents (hexane, chloroform and methanol) against human pathogenic microorganism. Methods: Preliminary phytochemical screening of leaf extracts (in different solvents) of A. brasiliana were qualitatively tested using standard procedures. Thin...

The powder of root bark of Malva parviflora (Malvaceae) was successively extracted with petroleum ether (b.p. 60-80 °C), chloroform and ethanol. The chloroform extract showed antibacterial activity against Staphylococcus aureus and Escherichia coli, whereas the ethanolic extract showed antibacterial activity against only S. aureus. The chloroform extract, after column chromatographic separation...
