METHOD The chemical constituents were isolated and purified by various chromatographic methods, and their structures were identified by NMR and MS data analysis. RESULT Five compounds were obtained and identified as falcarindiol (1), 8-hydroxy-l-methoxy-( Z) -9-heptadecene-4, 6-diyn-3-one (2) angenomalin (3), scopoletin (4), O-methylnotopterol (5).
