Fund Project: The authors thank Zhao Hui-Nan, Mu Zhen-Qiang and Duan Ying-Hui for the measurements of HR-TOF-MS data. We are grateful to Huang Jing-Hui and Li Ling for measuring the NMR and ESIMS spectra. Thanks are also given to Liu Yuan for UV and IR data.

A new protoberberine alkaloid, named 5,6-dihydro-10-hydroxy-2,3,9-trimethoxy-13-methyldibenzo[a,g]quinolizinium (1) was isolated from the 60% ethanol extract of the tubers of Corydalis yanhusuo W. T. Wang, together with a new natural product, 13-methylpalmatrubine (2). Their structures were established by spectroscopic methods.
