摘要：
From the stem of Calotropis procera, olean-12-en-28 oic acid-3-O-alpha -L-rhamnopyranosyl (1-->2) beta -D-glucopyranosyl (1-->2) beta -D-galactopyranoside 1 and 3-O-{beta- D-glucopyranosyl (1-->2)-beta -D-glucopyranosyl (1-->6)-beta- D-glucopyranosyl (1-->3)-alpha -L-arabinopyranoside} olean-12-en-28-O-beta -D-glucopyranosyl 2 have been isolated. Their structures have been elucidated on the basis of spectral data and by chemical methods.
