OBJECTIVE To investigate the constituents of the stem of Rabdosia excisa. METHODS Compounds were separated and purified by silica gel column chromatography and their structures were determined by spectroscopic method. RESULTS Thirteen compounds isolated from this plant were identified as rabdesimte( 1 ), maoyecrystal E (2), 6beta,11alpha,15alpha-trihydroxy-6,7-seco-6,20-epoxy-1alpha, 7-ol-ide-ent-kaur-16-en (3), enmenol-glucoside (4), oridonol (5), macrocalyxin G (6), rabdosichuanin C (7), beta-sitosterol (8), ursolic acid (9), 2alpha-hydroxyursolic acid (10), maslinic acid ( 11 ), 2alpha,3alpha,19-trihydroxy-urs-12-en-28-oicacid (12), and daucosterol (13). CONCLUSIONS Except for compounds 5, 8, 9 and 13, the remaining compounds were found in R. excisa for the first time.
