Twelve compounds, including 5 new monoterpenes and 7 known derivatives, 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 enzymatic hydrolysis as well as electronic circular dichroism (ECD) and NMR calculations, the new structures named monochaside I (1) and monochairidols A-D (2-5), respectively. The known compounds 6-12 were obtained from the Monochasma plants for the first time.
