Abstract

Eight new sacculatane-type diterpenoids, named 12-deoxy-1β, 11α-dihydroxy-sacculatanolide (1), 11α-hydroxysacculatanolide (2), pellianolactones A, B, (3, 4), 1β, 11α-dihydroxysacculatanolide (5), 1β-hydroxysacculatal (6), 1β-hydroxy-isosacculatal (7), and 1β-hydroxysacculatanolide (8), have been isolated from the liverwort Pellia endiviifolia.
