Abstract:
OBJECTIVETo investigate the constituents of the stem of Rabdosia excisa.
METHODCompounds were separated and purified by silica gel column chromatography and their structures were determined by spectroscopic method.
RESULTThirteen 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).
CONCLUSIONExcept for compounds 5, 8, 9 and 13, the remaining compounds were found in R. excisa for the first time.
