title: 9,19-cyclolanostane derivatives from the roots of Actaea pachypoda.
abstract: Phytochemical investigation of the chemical constituents of the roots of Actaea pachypoda afforded 12 9,19-cyclolanostane type triterpenoids, including the new 7,8-dihydroactaeaepoxide 3-O-beta-d-xylopyranoside (1), 12-deacetoxyactaeaepoxide 3-O-beta-d-xylopyranoside (2), and 12beta-acetoxycimigenol (3). Their structures were determined by spectroscopic and chemical methods.
