Five partially-acetyalated derivatives (1)-(5) of 1-O-dodecanyl α-L-rhamnopyranosyl-(1->3)-α-L-rhamnopyranosyl-(1->3)-α-L-rhamnopyranosyl-(1->4)-α-L-rhamnopyranoside have been isolated from the stem bark of Cleistopholis glauca (Annonaceae) and their structures elucidated by using COSY, delayed COSY, and FAB Mass spectroscopy.The trisaccharide 1-O-dodecanyl α-L-2,3,4-triacetylrhamnopyranosyl-(1->3)-α-L-4-acetylrhamno-pyranosyl-(1->4)-α-L-rhamnopyranoside (6) was also isolated.
