An unprecedented 4,9‐seco‐oplopanane (1), two undescribed drimane epimers (2 and 3), and five known drimane sesquiterpenoids (4–8) were isolated from the Chinese liverwort Lejeunea flava (Sw.) Nees. The structures of the new sesquiterpenoids were determined using nuclear magnetic resonance spectrosc...
