Gas Chromatography-Mass Spectrometry Analysis, in Vitro Cytotoxic and Antioxidant Efficacy Studies on Cleome Gynandra L. (Leaves): A Traditional Drug Source

Abstract

Objective: This study was aimed to assess the phytoconstituents, cytotoxic, and antioxidant efficacy of ethyl extract of Cleome gynandra leaves.Methods: Qualitative phytochemical analysis with different solvent extracts was performed. Quantitative and gas chromatography-mass spectrometry (GC-MS) analysis of the extract was performed with ethyl acetate extract. The cytotoxic effect of the ethyl acetate extract was determined by 3-[4,5-dimethylthiazol-2-yl]2,5-diphenyltetrazolium bromide (MTT) assay on Michigan Cancer Foundation-7 (MCF-7) cells using taxol as standard and free radical scavenging ability using 1,1-diphenyl-2-picrylhydrazyl (DPPH). Results:Leaves extracts with different solvents revealed the presence of alkaloids, cardiac glycosides, flavonoids, phenols, and tannins. GC-MS analysis of ethyl acetate of the plant leaves showed the presence of n-hexadecanoic acid. The IC 50 value of the ethyl acetate extract was found to be 90.2 μg/ml on MCF-7 cell line, and the extract was found to possess significant DPPH free radical scavenging activity. Conclusion:From the results, we conclude that the C. gynandra extract possesses antioxidant and antiproliferating activity against MCF-7 cells.
