Abstract

From the petroleum-ether ext. of the dried aerial parts of Hypericum papuanum, three new prenylated tricyclic and four new bicyclic acylphloroglucinol derivs. were isolated by bioactivity-guided fractionation. The structures of the bicyclic compds. enaimeone A, B, and C (e.g. I, enaimeone A) were elucidated as ...
