Groenlandicine 是来自黄连的一种原小檗碱生物碱，能诱导拓扑异构酶 I 介导的 DNA 裂解。它对人类重组醛糖还原酶(HRAR)具有中度的抑制作用，IC50值为 154.2 μM。

Groenlandicine is a protoberberine alkaloid from Coptidis Rhizoma. Groenlandicine exhibits moderate inhibitory effect with IC50 value of 154.2 μM for human recombinant aldose reductase (HRAR). Groenlandicine selectively induces topoisomerase I-mediated DNA cleavage;Groenlandicine may be a promising anti-Alzheimer's disease agent due to its potent inhibitory activity of both ChEs and beta-amyloids formation, as well as marked ONOO(-) scavenging and good ROS inhibitory capacities.

Isolated alkaloids from Coptis chinensis Franch. The compounds were identified as berberine, columbamine, Groenlandicine, jatrorrhizine, magnoflorine, corydaldine and ferulic acid methylester. Then measured their bitter degree based on the electronic tongue and evaluated the antibacterial. The results based on the Electronic Tongue showed that berberine, columbamine, Groenlandicine and jatrorrhizine have higher bitter degree than magnoflorine and corydaldine. And they also appeared better antibacterial activity on E. coli and S. aureus. The correlation coefficients between bitter degree and the two bacteria antibacterial activity were 0.983 and 0.911[1]
