【 摘 要 】
Threenew minor diterpene glycosides were isolated from the commercial extract of the leaves ofStevia rebaudianaand their structures were identified as 13-[(2-O-b-D-glucopyranosyl-b-D-glucopyranosyl)oxy]ent-kaur-15-en-19-oic acidb-D-glucopyranosyl ester (1),13-[(2-O-b-D-glucopyranosyl-3-O-b-D-glucopyranosyl-b-D-glucopyranosyl)oxy]ent-kaur-15-en-19-oic acidb-D-glucopyranosyl ester (2) and 13-[(2-O-b-D-glucopyranosyl-3-O-b-D-glucopyranosyl]-b-D-glucopyranosyl)oxy] 17-hydroxy-ent-kaur-15-en-19-oic acidb-D-glucopyranosyl ester based on extensive spectroscopic data and chemical studies.
