摘要：

Two new glycosides, hancoside [1] and neohancoside A [2] have been isolated from Cynanchum hancockianum along with five known compounds, antofine, cynatratoside A, daucosterol, (-)-leucanthemitol, and sinapic acid. Compounds 1 and 2 are established as 3beta,14beta,15beta-trihydroxypregn-5-en-20-one 3beta-0-beta-D-(6-0-sinapoyl)-glucopyranosyl-(1-->2)-beta-D-glucopyranoside [1] and linalool 3-0-beta-D-xylopymnosyl-(1-->6)-beta-D-glucopyranoside [2] by spectroscopic analysis.
