title: A new triterpenoid saponin from Artemisia sphaerocephala.
abstract: The ethanol extract of the whole plant of Artemisia sphaerocephala yielded a new and a known triterpenoid saponin, which were identified by spectroscopic techniques. The new compound was identified as (3beta, 16 beta, 21 beta)-16,21,28-trihydroxyolean-12-en-3-O-beta-D-glucopyranosyl(1 --> 2)-beta-D-glucuronopyranoside.
