Abstract:
Objective: To study the chemical constituents of Ixeris chinensis. Methods: The chemical constituents were isolated and purified by chromatography of silica gel column and HPLC, and their structures were elucidated by spectral analysis. Results: Nine triterpenoids were isolated and identified as 20α-peroxide-3β-uvaol-21-en (1), 3β,21α-dihydroxylupen-18-en (2), 3β,25-dihydroxy-tirucalla-7,23-diene (3), 21α-hydroxy-taraxasterol-20(30)-en (4), lupeol (5), 3β-uvaol (6), 3β-oleanol-18-en (7), 3β-oleanol (8), and 3β-uvaol-20-en (9). Conclusion: Compound 1 is a new compound, named ixeritriterpenol, and compound 7 is isolated from I. chinensis for the first time.
