Isoliensinine (isolie) is an alkaloid produced by the edible plant Nelumbo nucifera. Here, we unveiled that isolie was able to provoke HepG2, Huh-7, and H22 hepatocellular carcinoma (HCC) cell apoptosis. Isolie decreased NF-κB activity and constitutive phosphorylation of NF-κB p65 subunit at Ser536
Simultaneous determination of liensinine, isoliensinine and neferine from seed embryo of Nelumbo nucifera Gaertn. in rat plasma by a rapid HPLC method and its application to a pharmacokinetic study.

The effects of isoliensinine (IL), a bisbenzylisoquinoline alkaloid extracted from the Chinese traditional medicine seed embryo of Nelumbo nucifera Gaertn., on bleomycin (BLM)-induced pulmonary fibrosis in mice were investigated. Seventy-two male Kungming mice were divided randomly into eight groups
Serotonergic mechanisms are involved in antidepressant-like effects of bisbenzylisoquinolines liensinine and its analogs isolated from the embryo of Nelumbo nucifera Gaertner seeds in mice.

OBJECTIVE
We attempted to ascertain if bisbenzylisoquinoline alkaloids, liensinine and isoliensinine from Nelumbo nucifera Gaertner have antidepressant-like effects and compare the effects with those previously obtained by their analogue neferine.
METHODS
Using mice, the forced swimming test (FST)
