ABSTRACT
Eleven monoterpene glucosides were isolated from a water decoction of Monochasma savatieri by column chromatography over macroporous adsorbent resin, MCI resin, Sephadex LH-20, and HW-40C, combined with preparative TLC, reversed phase HPLC, and flash column chromatographic techniques. Their structures were elucidated by comprehensive analysis of spectroscopic data, along with acidic and enzymatic hydrolysis as well as electronic circular dichroism (ECD) and NMR calculations, including six new compounds (1-4, 7 and 8), named monochasides A-D, G and H, respectively. Comparing the reported data of 9-hydroxylinaloyl 3-O-β-D-glucoside (5), (6Z)-9-hydroxylinaloyl 3-O-β-D-glucoside (6), and kankanoside D1 (9) with those obtained in this study, the absolute configurations of 6 and 9 were proved for the first time. Other two compounds were identified as 8-hydroxygeraniol 1-O-β-D-glucopyranoside (10) and 8-hydroxygeraniol 8-O-β-D-glucopyranoside (11), respectively.
