概要
Ten alkaloids were isolated from the bulb of CORYDALIS HSUCHOWENSIS W. Y. Lian nov. ined. Among them nine alkaloids are known, identified as (-)-stylopine ( 1), cheilanthifoline ( 2), (+)-adlumidine ( 3), (+)-bicuculline ( 4), sibiricine ( 5), humosine A ( 6), (+)-bulbocapnine ( 7), (-)-scoulerine ( 8), and protopine ( 10), respectively. The other one is a new isoquinoline alkaloid. The structure was deduced as 9 based on spectroscopic analysis and chemical reactions. It was named coryximine.
