Chemical Analysis of Burdock Root Constituents

Chemical constituents of the root of Jasminum giraldii.

Two new compounds, ethylconiferin and (-)-lariciresinol 4-(6'''-O-cinnamyl-β-D-glucopyranoside), along with the three known compounds (+)-pinoresinol, (+)-cycloolivil, nobiletin, were isolated from the root of Jasminum girialdii. All these compounds were isolated for the first time from this source. Their structures were elucidated on the basis of extensive spectroscopic analysis and chemical m...

Chemical constituents from the root bark of Ozoroa insignis

The roots of Ozoroa insignis Del. (Heeria insignis Del.) (Anacardiaceae) are used as a remedy for diarrhea, venereal diseases, tapeworm and hookworm, schistosomiasis, kidney trouble, migraine, and malaria (Liu and Abreu, 2007). In previous biological screening of O. insignis extracts, anthelmintic effect, cytotoxic activity, and topoisomerase inhibition were reported (Liu and Abreu, 2006a). The...

Analysis of the Chemical Constituents of Agaricus brasiliensis

This study examined the chemical composition of A. blasiliensis and the chemical structural properties of an immuno-stimulating polysaccharide. The amino acids, free sugars, and organic acids by HPLC and fatty acids by GC were analyzed. The immuno-stimulating substance from A. blasiliensis was extracted with hot water and purified by ethanol precipitation. It underwent ion exchange chromatograp...

Chemical Constituents of Salvia aegyptiaca

The essential oil of Salvia aegyptiaca was analysed by GC/ MS technique. Eighteen compounds were identified. It was found that the essential oil comprises 40% terpenoidal constituents, opposite to 32% fat derivatives. The major terpenoidal component was 1(10)aristolene (19.3%). From the non-volatile matter, β-amyrin, lupeol, β-sitosterol, stigmasterol, β-sitosterol-β-D-glucopyranoside and stigm...
