Structures of Novel Sesquiterpene Alcohols from Chloranthus japonicus (Chloranthaceae)

Abstract

Three novel sesquiterpene alcohols, shizuka-acoradienol (2), shizukafuranol (3) and shizukolidol (4), were isolated from Chloranthus japonicus Sieb. (Japanese name: Hitori-shizuka, Chloranthaceae). Their structures were elucidated on the basis of their physicochemical properties and some chemical reactions. Furanodienone (5), scopoletin (6a) and isoscopoletin (6b) were also isolated from this plant.
