Background: Cyclea peltata (Lam.) Hook. f. and Thoms., an ethnomedicinal herb with antitoxin and anti-herpes activities, is used to cure smallpox, wounds, diabetic disorders of the skin, and its use as a cooling agent. In the present study, an attempt has been made to screen different alkaloids present in Cyclea peltata roots using LC-ESI-MS/MS and to evaluate the in vitro cytotoxic activity of alkaloids.

Methods: The detection of alkaloids in C. peltata root extract was carried out by performing MRM-based assay using liquid chromatography-mass spectrometry. The cytotoxic effect of the acetone crystalized fraction was performed against human pancreatic cancer using MIA PaCa-2 cells.

Results: The study revealed the presence of tetrandrine and fangchinoline as the major BBI alkaloids in the roots of this herb, along with cycleacurine, isochondrodendrine, cycleahomine and tetrandrine mono-N-2’-oxide. Furthermore, the present study also detected two precursors of BBI alkaloids such as d-Coclaurine, (-)-N-methylcoclaurine. The study also showed a significant (p<0.05) cytotoxic effect of the acetone crystalized fraction with an IC50 value of 59.85 μg/ml.

Conclusion: C. peltata root is the major source of tetrandrine and fangchinoline with potent cytotoxic effect.

Keywords: Cyclea peltata, LC-ESI-MS/MS, tetrandrine, fangchinoline, cytotoxicity, alkaloids.
