Chemical constituents of Hoya buotii Kloppenb
Chemical investigation of the dichloromethane extracts of Hoya buotii Kloppenb. afforded taraxerone (1), taraxerol (2), a mixture of ß-sitosterol (3a) and stigmasterol (3b) in about 2:1 ratio, and a mixture of α-amyrin cinnamate (4a) and ß-amyrin cinnamate (4b) in about 1:2 ratio from the stems; 1,...
