摘要
From the ether extract of Porella perrottetiana a new sacculatane-type diterpene hemiacetal, sacculaporellin was isolated together with the previously known trans-labda-12,14-dien-8α-ol, trans-labda-12,14-dien-7β,8α-diol and perrottetianal and its structure characterized by 1H and 13C NMR experiments. The methanol extract of Heteroscyphus bescherellei contained a furanoditerpenic acid, ent-junceic acid as the major component. There is no chemical affinity between Heteroscyphus, Chiloscyphus and Lophocolea species belonging to the Lophocoleaceae. © 1990.
