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.
