摘要：

Five new kaurene-type bitter diterpene glucosides, infuscasides AE, have been isolated from the liverwort Jungermannia infusca together with the previously known ent-15α-hydroxykaurene and stigmasteryl glucoside and their structures elucidated by chemical data and the extensive 2D-COSY NMR spectroscopy. The new diterpenoids have a very bitter taste. © 1990.
