Abstract

A new dammarane-glycoside, ginsenoside Rz₁ (1), was isolated from heat-treated Panax ginseng C. A. MEYER (Araliaceae) with ginsenosides Rk₁ and Rg₅. The structure of 1 was established to be (Z)-12β-hydroxydammara-20(22),24-dien-3β-yl O-β-D-glucopyranosyl-(1→2)-β-D-glucospyranoside by spectroscopic means. HPLC analyses revealed that the ginsenosides Rz₁, Rk₁, and Rg₅ were present in the ratios of 1 : 2 : 6, respectively.
