Alpinia zerumbet is used in folk medicine in Brazil to treat hypertension. However, several pathways involved in the mechanism of vasorelaxation are still unclear. This study was designed to verify the antihypertensive effect of the methanolic fraction of the essential oil of A. zerumbet (MFEOAz) and to characterize its mechanism of action. The thoracic aortic rings from the Wistar rats were pe...
Jackfruit contains high-value biological compounds (HVBC) with important activity in the inhibition of carcinogenesis, through various mechanisms. This study aimed to identify HVBC a methanolic fraction an extract jackfruit; which was reported antimutagenic and antiproliferative against PC3 cells (prostate cancer). The profile includes 3 organic acids, 5 phenolic 12 flavonoids, 2 carotenoids. i...
this study was carried out to evaluate the antimicrobial and antioxidant effectiveness of methanolic extract and different fractions (n-butanol, ethyl acetate, chloroform and n-hexane) of c.intybus seeds. the antimicrobial activity was determined by the disc diffusion method and minimum inhibitory concentration (mic) against a panel of microorganisms (four bacterial strains, i.e. p. multocida, ...
rosmarinus officinalis l., a medicinal herb from the labiates family, has been reported to be of potential benefit in the treatment and prevention of several diseases. in particular its phenolics have demonstrated protective effects on various types of cancer through several mechanisms. the present study aimed to determine the effects of rosemary phenolic extracts on human cell functions, with ...
Cheilanthes grisea Blanford, a rare fern of Kumaun hills, is a member of psinopteridaceae family of leptosporangiate group of ferns. Aq. methanolic extract (50%) of this fern was screened for antifungal activity by thin layer autobiochromatographic methods. Chemical investigation of the fern fronds of C. grisea Blanford revealed the presence of a flavonol glycoside, quercetin-3-O-β-glycosyl (1→...
This study was designed to investigate the antimicrobial activity of Cinnamomum iners standardized leave methanolic extract (CSLE), its fractions and isolated compounds. CSLE and fractions were subjected to disc diffusion, minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) tests using different Gram positive and Gram negative bacteria and yeast. Within the serie...
Eleusine indica (Linnaeus) Gaertner is a traditional herb known to be depurative, febrifuge, and diuretic and has been reported with the highest inhibitory activity against porcine pancreatic lipase (PPL) among thirty two plants screened in an earlier study. This study aims to isolate and identify the active components that may possess high potential as an antiobesity agent. Of the screened sol...
The methanolic extract of the root of Garcinia multifl ora and its derived soluble fractions, namely those soluble in ethyl acetate (EtOAc), n-butanol, and water, were screened for their antioxidant activities. Among them, the EtOAc-soluble fraction exhibited the highest scavenging activity against the 1,1-dipheny1–2-picrylhydrazyl radical, the highest superoxide radical scavenging activity, an...
The aim of this study was to characterize and optimize the different hydrogel formulations of the methanolic root extract of Buchanania lanzan (MEBL) with an objective towards the development of a suitable topical delivery system. The gel formulations were prepared with different concentrations of polymer (Carbopol-940) and 0.5% of the active fraction (ethyl acetate sub-fraction of MEBL). Diffe...
Calligonum comosum (Polygonaceae), an Egyptian desert plant, was extracted and fractionated using petroleum ether, methylene chloride, and ethyl acetate. The total methanolic extract and other fractions were tested for their anticancer activity using Ehrlich ascites, brine shrimp and antioxidant assays. Ethyl acetate fraction proved to be the most active in all assays. Eight compounds were isol...
