Summary: | Peperomia pellucida leaf extract was characterized for its anticancer, antimicrobial, antioxidant
activities, and chemical compositions. Anticancer activity of P. pellucida leaf extract was determined through
Colorimetric MTT (tetrazolium) assay against human breast adenocarcinoma (MCF-7) cell line and the
antimicrobial property of the plant extract was revealed by using two-fold broth micro-dilution method
against 10 bacterial isolates. Antioxidant activity of the plant extract was then characterized using α, α-
diphenyl-β-picrylhydrazyl (DPPH) radical scavenging method and the chemical compositions were screened
and identified using gas chromatography-mass spectrometry (GC-MS). The results of present study indicated
that P. pellucida leaf extract possessed anticancer activities with half maximal inhibitory concentration (IC50)
of 10.4±0.06 μg/ml. The minimum inhibitory concentration (MIC) values were ranged from 31.25 to 125
mg/l in which the plant extract was found to inhibit the growth of Edwardsiella tarda, Escherichia coli,
Flavobacterium sp., Pseudomonas aeruginosa and Vibrio cholerae at 31.25 mg/l; Klebsiella sp., Aeromonas
hydrophila and Vibrio alginolyticus at 62.5 mg/l; and it was able to control the growth of Salmonella sp. and
Vibrio parahaemolyticus at 125 mg/l. At the concentration of 0.625 ppt, the plant extract was found to inhibit
30% of DPPH, free radical. Phytol (37.88%) was the major compound in the plant extract followed by 2-
Naphthalenol, decahydro- (26.20%), Hexadecanoic acid, methyl ester (18.31%) and 9,12-Octadecadienoic
acid (Z,Z)-, methyl ester (17.61%). Findings from this study indicated that methanol extract of P. pellucida
leaf possessed vast potential as medicinal drug especially in breast cancer treatment. |
