Description
Summary:<abstract language="eng">The chemical investigation of the hexane and ethanol extracts from aerial parts of Vernonia chalybaea conducted to the isolation and characterization of a new aliphatic tetrahydroxyl ether, along with a series of known compounds such as 4 &#945;,10 &#945;-epoxyaromadendrane, friedelin, taraxasteryl acetate, pseudotaraxasteryl acetate, lupeyl acetate, lupeol, &#945;-amiryn, &#946;-amiryn, &#946;-sitosterol, stigmasterol, 2,3-dimethyl-1,2,3-tri-hydroxybuthanol, angophorol, angophorol-7-O-glucoside, angophorol-7-O-rutinoside, 3,7-dimethoxy-5,3',4'-trihydroxyflavone and acacetin. The structures of all compounds were determined by spectroscopic analysis and comparison with published spectral data.
