Four new sesquiterpenes, chlorajapolides F-I (1-4), along with nine known terpenoids (5-13) were isolated from the aerial part of Chloranthus japonicus. Their structures were elucidated on the basis of spectroscopic analysis, and a lindenane sesquiterpene, named 9-hydroxy-heterogorgiolide, previously isolated from the C. japonicus, was revised as its 8-epimer (1a). Moreover, methanol extract (ME), EtOAc fraction (EF), water fraction (WF), and all isolates (1a, 1-13) were evaluated for their cytotoxicities using two human cancer cell lines.
