Objective To investigate the chemical constituents of Rabdosia phyllopoda. Methods The chemical constituents were isolated and purified by chromatography with silica gel, Sephadex LH-20 and by semi-preparative HPLC, and their structures were identified by analysis of spectroscopic evidences and physicochemical properties. Results A total of 14 constituents were isolated from R. phyllopoda and elucidated as (Z)-1,1'-biindenyliden (1), β,β-carotene (2), germacrene B (3), 2α,3α,24-trihydrxyolean-12-en-28 oic acid (4), ferulic acid hexacosanyl ester (5), ergosterol peroxide (6), ursolic acid (7), α-amyrin acetate (8), obtusalin (9), betulinic acid (10), 2α,3α,19α-trihydroxy-12-en-28-urs acid (11), 2α,3α-dihydroxyl-12-ene-28 oic acid (12), 2α-hydroxyursolic acid (13), and lutein (14). Conclusion The 14 compounds are isolated from this plant for first time, and compound 1, 3, 6, 9, 14 are isolated from the plants of R. phyllopoda for the first time.
