Main Article Content
Abstract
Ginsenoside Rgl, { 3β, 6α, 12 β, 20S-tetrahydroxydammar-24-en 6-O-[β -D-glucopyranoside]}; gypenoside XVII {(3β,12β)-20-[(6-O-(β-D-glucopyranosyl)-β-D-glucopyranosyl)oxy]-12-hydroxydammar-24-en-3-yl β-D-glucopyranoside}. These compounds were elucidated using a combination of UV, IR, 1D and 2D NMR techniques (1H-, 13C-NMR, COSY, HSQC and HMBC) and MS analyses.
