[Studies on the alkaloids from herb of Corydalis adunca].
OBJECTIVE
To study the alkaloid constituents of Corydalis adunca.


METHODS
The constituents were isolated on silica gel column and their structures were elucidated by IR, NMR, MS data.


RESULTS
Four alkaloid compounds were isolated from alcohol extract of the herb of C. adunca, and identified as tetrahydropalmatine, 1, 2, 3, 4-tetrahydro-6-methoxy-1-(4'-methoxyphenyl) methyl-7-isoquinolinol, coptisine and palmatine.


CONCLUSIONS
Four compounds were isolated from C. adunca for the first time.
