Isolation and Identification of Terpenoids from the Fruits of Acanthopanax chiisanensis

ABSTRACT

Phytochemical constituents were isolated from the fruits of Acanthopanax chiisanensis by repeated column chromatography. Their structures were identified as beta-sitosterol (1), daucosterol (2), sesamin (3), chiisanogenin (4), and 22alpha-hydroxy chiisanogenin (5) by spectroscopic analysis (MS, 1H-, and 13C-NMR). Compounds 1 - 5 were isolated for the first time from the fruits of A. chiisanensis.
