Abstract

OBJECTIVE: To study the alkaloid constituents of Corydalis adunca. METHOD: The constituents were isolated on silica gel column and their structures were elucidated by IR, NMR, MS data. RESULT: 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. CONCLUSION: Four compounds were isolated from C. adunca for the first time.
