摘要：

Jacaranone and related compounds (1-3) were isolated, along with three triterpenes (4-6), from the fresh fruits of Ternstroemia japonica. The compounds were identified as jacaranone (1), 3-hydroxy-2,3-dihydrojacaranone (2), 3-methoxy-2,3-dihydrojacaranone (3), 3-O-acetyloleanolic acid (4), 3-O-acetylursolic acid (5), and ursolic acid (6). Jacaranone and its derivatives were isolated for the first time from Theaceae. Of the isolated compounds, compound 3 is a new compound. Jacaranone (1) exhibited weak antioxidative effect on 1,1-diphenyl-2-picryl-hydrazyl (DPPH) radical.
