A new ent-kaurane glycoside, subpubescensoside, was isolated from the
leaves of Stevia subpubescens. Its structure was elucidated as 11 beta
,16-oxo-ent-kauran-19-oic acid 19-0-[beta-D-glucopyranosyl(1 --> 2)]-[
beta(-)D-glucopyranosyl(1 --> 3)]beta-D-glucopyranosyl ester on the ba
sis of spectroscopic and chemical evidence.
