Chemical Study on the Alkaloids of Corydalis hsuchowensis
05 January 2007 (online)
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.
