New Steroidal Erythrityl Triesters from the Heat Processed Roots ofPanax ginseng

Abstract

Two new compounds stigmasta-3α-ol-3α-(2′R,3′S)-butane-1′,2′,3′,4′-tetraolyl-2′,3′-dioctadec-9″/9‴-enoyl-4′-octadec-9″″,12″″-dienoate (1) and stigmasta-5-en-3β-ol-3β-(2′R,3′S)-butane-1′,2′,3′,4′-tetraolyl-2′,3′-dioctadec-9″/9‴-enoyl-4′-octadec-9″″,12″″-dienoate (2) along withβ-sitosterol-β-D-glucoside were isolated and identified from the heat processed roots ofPanax ginseng. The structures of the new compounds were elucidated by 1D and 2D NMR (COSY, HSQC, and HMBC) spectroscopic techniques aided by FAB-MS, ESI FT/MS, and IR spectra.
