title: A cyclic peroxide of clerodenoic acid from the Taiwanese liverwort Schistochila acuminata.
abstract: Two minor diterpenoids, 15(16)-peroxy-3, 13-clerodadien-18-oic acid (4) and totarol (7), were isolated from the liverwort Schistochila acuminata. The former is a further oxidized cyclic peroxide from the major component. The latter is a rearranged abietane alcohol which skeleton was found in liverworts for the first time.
