Constituents of Torilis japonica D.C. I. Isolation and Optical Purity of Germacra-4 (15), 5 (E), 10 (14)-trien-1β-ol

Abstract

Humulene (I), (-)-germacrene-D (II), and (-)-germacra-4 (15), 5 (E), 10 (14)-trien-1β-ol (III) were isolated from the fruits of Torilis japonica. the latter two compounds (II and III) were determined to have optical purities of about 40 and 30%, respectively.
