OBJECTIVE
To study the chemical constituents of Corydalis humosa Migo.
METHODS
Some chromatography methods were used to separate the chemical constituents of this plant. Their structures were determined by NMR and MS spectral data.
RESULTS
Six compounds were isolated from the 95% ethanolic extract of the tubers of C. humosa. The structures of these compounds were identified as tetrahydropalmatine (1), jatrorrhizine (2), berberine (3), tetrahydroberberine (4), palmaline (5) and (-)-tetrahydrocoptisine (6) respectively.
CONCLUSIONS
Compounds 1-3 were isolated from this plant for the first time.
