The pregnane glycoside marsdekoiside a from Marsdenia koi
摘要:
A new pregnane glycoside, marsdekoiside A was isolated from the stems of Marsdenia koi (Asclepiadaceae) and its structure was elucidated from chemical and spectral data as 12-cinnamoyl-dihydrosarcostin-3-O-methyl-6-deoxy-beta-D-allopyr ano syl-(1----4)-O-beta-D-oleandropyranosyl-(1----4)-O-beta-D-++ +cymar opyranoside.
