Abstract;The ether extracts of three liverworts, Frullania inflata, Leptoscyphus jackii and Wiesnerella denudata were chemically analyzed. The Indian F. inflata contains the germacrane-type sesquiterpene lactone, (11S)- 11,3-dihydrolipiferolide (=8.BETA.-acetoxydihydroparthenolide), together with eight sesquiterpene hydrocarbons, .ALPHA.-cubebene, .BETA.-cubebene, .ALPHA.-copaene, .BETA.-caryophyllene, germacrene-A, .ALPHA.-selinene, .BETA.-selinene and .BETA.-guaiene. The Ecuadorian, L. jackii is chemically very simple. It produced a new maaliane-type sesquiterpene alcohol, ent- 1.ALPHA.-hydroxy-3-maaliene as a major component, with (-)-bicyclogermacrene. Its structure was elucidated by spectroscopic means. From the Japanese W. denudata two germacranolides and three guaianolides were obtained. F. inflata is classified to the sesquiterpene lactone-type (Chemo-type I). There are two chemo-types of W. denudata. (author abst.)
