Objective To study the chemical constituents from the rhizome of Tripterygium hypoglaucum. Methods The concrete exacted by 95% ethanol from the rhizome of T. hypoglaucum was isolated and purified by chromatography on silica gel column chromatography, gel column chromatography, MPLC, etc. The structures of the chemical constituents were elucidated by means of NMR, MS, etc. Results Twelve compounds were isolated and identified as 3β-hydroxy-4-hydroxymethyl-abieta-8,11,13-trien-7-one (1), 3β-acetoxy oleanolic acid (2), physcion (3), canophyllal (4), chrysophenol (5), quinone 21 (6), tripterifordin (7), triptobenzene B (8), 3,4-dimethoxyphenol (9), integracin A (10), celastrol (11), and β-sitosterol (12). Conclusion Compound 1 is a new diterpene named tripterone, compounds 8-10 are isolated from this plant for the first time.
