Abstract

A new minor diterpene glycoside has been isolated from a commercial extract of the leaves of Stevia rebaudiana and its structure was identified as 13-[(2-O-β-D-glucopyranosyl-β-D-glucopyranosyl)oxy] ent-kaur-16-en-19-oic acid-[2-O-(2-O-β-D-glucopyranosyl)-β-D-glucopyranosyl-3-O-b-D-glucopyranosyl-β-D-glucopyranosyl] ester (1) based on extensive NMR (1D and 2D) and mass spectroscopic data, and hydrolysis studies.
