Objective To study the chemical constituents from the root of Lasianthus acuminatissimus. Methods The compounds were isolated and purified by silica gel column chromatography, Sephadex LH-20, ODS column chromatography, preparative HPLC and so on. Their structures were determined on the basis of physicochemical properties and their spectroscopic data, as well as literature. Results A total of 16 compounds were separated and identified as 4-methoxyphenol (1), 3-acetylbetulinic acid (2), palmitic acid (3), 3,8-dihydroxy-2-ethoxymethyl-1-methoxy-9,10-anthraquinone (4), 1,3-dihydroxy-2-ethoxymethyl-9,10-anthraquinone (5), 1,3-dihydroxy-2-methyl-9,10-anthraquinone (6), 3,8-dihydroxy-1-methoxy-9,10-anthraquinone (7), 3-hydroxy-1-methoxy-9,10-anthraquinone (8), 1,3-dihydroxy-2-methoxymethyl-9,10-anthraquinone (9), 4-hydroxymethyl-2-furaldehyde (10), butyl benzyl phthalate (11), lasianthurin A (12), isoscopletin (13), damnacanthol (14), uncargenin A (15), and lasianthuoside A (16). Conclusion Compounds 1—11 are isolated from the genus of Lasianthus for the first time.
