A phytochemical investigation of MeOH extract of Desmos cochinchinensis var. fulvescens Ban afforded two new compounds, 1 β ,7 α ‐dihydroxyeudesman‐4‐one ( 1 ) and 5 αH ‐megastigm‐7‐ene‐3 α ,4 α ,6 β ,9‐tetrol ( 2 ), together with nine known terpenoids. The structures of the new compounds were elucidated by 1D‐ and 2D‐NMR spectroscopic analysis. Their relative configurations were assigned by NOESY experiments.
