摘要: Abstract Aim To study the chemical constituents of Macleaya cordata (Willd.) R. Br. Methods Crude alkaloids were isolated and purified from fruits with column chromatography cation exchange, silica gel ad Sephadex LH-20 followed by recrystallization. The structure elucidation was carried out extensive spectroscopic methods. Results Two new benzophenanthridine isoquinoline alkaloids, 6 a -iso-butanonyldihydrosanguinarine ( 1 ) -iso-butanonyldihydrochelerythrine 2 ), along other four known alkaloid compounds, 6-acetonyldihydrosanguinarine 3 6-acetonyldihydrochelerythrine 4 dihydrosanguinarine 5 dihydrochelerythrine have been M. collected in Anhui Province China. Conclusion Benzophenanthridine are featured . Compounds ones.
