Objective To research the chemical constituents of Rabdosia excisa. Methods Compounds were separated and purified by silica gel column chromatography and their structures were determined by spectroscopic method. Results Fifteen compounds isolated from the leaves of this plant were identified as: hyptadienic acid (1), α-amyrin palmitate (2), stigmasterol (3), β-sitosterol (4), palmitic acid (5), ursolic acid (6), 1α, 6, 11β, 15β-tetraacetoy-6, 7-seco-7, 20-olide-ent-kaur-16-en (7), 2α, 3α-dihydroxy-urs- 12-en-28-oic acid (8), maslinic acid (9), 2α, 3α, 19-trihydroxy-urs-12-en-28-oic acid (10), maoyecrystal E (11); 6β, 11α, 15α- trihydroxy-6, 7-seco-6, 20-epoxy-1α, 7-olide-ent-kaur-6-en, epinodosinol (12), enmenol-glucoside (13), oridonol (14), and daucosterol (15). Conclusion All the constituents are found in R. excisa for the first time except constituents 3, 5, 6, 14, and 15.
