Triterpenoids from pyrethrum tatsienense.
Two novel and eight known triterpenoids were isolated from alcoholic extract of the whole plant of Pyrethrum tatsienense. The structures of new compounds were elucidated as olean-12-en-3beta,11alpha,16beta-triol-3-O-palmitate (1), ursa-12-en-3beta,11beta,16beta-triol-3-O-palmitate (2) by spectroscopic methods including intensive 2D NMR techniques (H1-H1 COSY, gHMQC, gHMBC) and FAB-MS, and the known compounds were identified on the basis of comparing their NMR data with those of corresponding compounds in the literature.
