Rebaudioside B

Rebaudioside B is a natural non-caloric sweetener. It is one of the minor steviol glycosides isolated from S. rebaudiana leaves. Rebaudioside C is metabolized by gut microbiota to steviol (Cay-10011344), a compound whose safety is widely studied.Formal Name: (4alpha)-13-[(O-beta-D-glucopyranosyl-(1->2)-O-[beta-D-glucopyranosyl-(1->3)]-beta-D-glucopyranosyl)oxy]-kaur-16-en-18-oic acid.
