Abstract

Five new prenylated tricyclic and three new bicyclic acylphloroglucinol derivs. have been isolated by bioactivity-guided fractionation of the petroleum ether ext. of the dried aerial parts of Hypericum papuanum. The tricyclic compds. (1-5) were named papuaforins A-E. The bicyclic compds. were isolated together with their corresponding tautomers and were named hyperguinones A and B (6/6a, 7/7a) ...
