Two new protoberberine quaternary alkaloids from Corydalis yanhusuo.
Two new protoberberine quaternary alkaloids, 13-methyl-palmatrubine (1) and 13-methyl-dehydrocorydalmine (2), were isolated from the tubers of Corydalis yanhusuo W.T. Wang. 1 was isolated as a natural product for the first time, and 2 a new compound. Their structures were elucidated on the basis of spectroscopic evidence, especially 1D- and 2D-NMR experiments.
