Abstract

Four new sphenolobane diterpenoids [(3R,6R,9R,10S)-sphenoloba-13E,16E,18-trien-4-one, (3R,6R,9R,10S)-18-hydroxysphenoloba-13E,16E-dien-4-one, (3R,6R,9R,10S)-sphenoloba-13E,17-dien-4-one, and (6R,9R,10S)-3α,4α-epoxysphenoloba-13(14),16E-dien-15,18-diol] have been isolated from the liverwort Anastrophyllum donnianum together with two previously known sphenolobanes [(6R,9R,10S)-3α,4α-epoxysphenoloba-13E,16E-dien-18-ol and (6R,9R,10S)-3α,4α-epoxysphenoloba-13E,17-diene] and four known sesquiterpenoids. Structures were established using spectroscopic methods. 1H and 13C NMR data of the new compounds and 13C data of 3α-acetoxybicyclogermacra-1(10),4-diene are reported.
