Objective: To investigate the chemical components of Tripterospermum chinense.
Methods: Various column chromatography were used in the isolation and purification,and physiochemical constant determination and spectral analysis were adopted to determine the chemical structures.
Results: A novel monoterpenoid and seven known compounds were isolated and identified as tripterospermum acid ester A( 1),strychnovoline( 2),p-hydroxybenzaldehyde( 3),isovitexin( 4),7-O-rhamnopyransoyl-isoorientin( 5),trifoliside( 6),2″-O-rhamnopyransoyl-trifoliside( 7) and sweroside( 8).
Conclusion: Compound 1 is a new monoterpenoid,compounds 2,3 are isolated from this plant for the first time.
