Objective To investigate the chemical constituents of Daphne gracilis. Methods The constituents were separated and purified by chromatographic methods and their structures were elucidated by spectroscopic methods and chemical analyses. Results Fifteen compounds were obtained and identified as β-sitosterol (1), friedelin (2), stigmast-4-ene-3-one (3), stigmast-4-ene-3, 6-dione (4), lupeol (5), stigmasterol (6), 1, 3-distearate glycerol (7), glycerin-docosanate (8), octadecanol (9), phytol (10), dehydrodiconiferyl alcohol (11), epoxyconiferyl alcohol (12), oleodaphnone (13), 14-gingerol (14), and matairesinol (15). Conclusion All the compounds are isolated from the plants of D. gracilis for the first time. Among them, compound 2—4, 7—9, 11, 12, and 14 are isolated from the plants in Daphne L. for the first time; Compounds 11, 12, and 14are isolated from the plants of family Thymelaeaceae for the first time.
