Nat Prod Commun 5(10):1557-60 (2010) PMID 21121247

Two new cycloartane glycosides were isolated from the whole herbs of Camptosorus sibiricus Rupr. By means of chemical and spectroscopic methods (1D and 2D NMR, HRMS, ESI-MS), the structures were established as (24R)-3beta,7beta,24,25,30-pentahydroxycycloartane-30-O-coumaroyl-3-O-beta-D-glucopyranosyl-24-O-beta-D-glucopyranosyl-(1 --> 6)-beta-D-glucopyranoside (1) and (24R)-3beta,7beta,24,25,30-pentahydroxy-1-ene-cycloartane 24-O-beta-D-glucopyranoside (2). The two new compounds were inactive in vitro against A375-S2 and Hela human tumor cell lines using the MTT method.
