Abstract
A new steroidal saponin, aferoside A, has been isolated from the roots of Costus afer. Its structure was established as 3-O-([beta-D-apiofuranosyl-(1-->2)]-[alpha-L-rhamnopyranosyl-(1--> 4)]-beta-D-glucopyranosyl)-25(R)-spirost-5-en-3 beta-ol by chemical transformations and various spectroscopic methods, mainly 2D NMR techniques (COSY, HMQC and HMBC).Entities:
