Abstract
Objectives; To identify the bioactive compounds present in Amorphophallus paeoniifolius and to evaluate the antioxidant and cytotoxic property of
the plant extract.
Methods; Preliminary phytochemical analysis was carried out to determine its major chemical constituents such as alkaloid.s, sterols, flavonoids,
terpenoids, phenolic compounds, saponins, carbohydrates, glycosides, and tannins. Bioactive compounds were identified by gas chromatography - mass
spectrometry (GC/MS) analysis. Antioxidant activity of the methanol extract were determined by two different methods viz., 2,2-diphenyl-2-picryl
hydrazyl hydrate radical scavenging assay and reducing power assay. Furthermore, the extracts were tested for their ability to kill the proliferative
cells (MCF-7) by (3-[4,5-dimethyl-thiazol-2-yl]-2,5-diphenyltetrazolium bromide) (MTT) assay.
Results; Ten pharmacology important compounds were identified by GC/MS analysis. The higher antioxidant potential of the extracts was observed
in both assays. The appreciable free radical scavenging activity of the extracts might be attributed to the secondary metabolites such as alkaloids,
flavonoids, tannin.s, phenols, and sterols present in the extract. The results of MTT a,ssay indicated a significant growth inhibition at a low concentration
of ICju values (51.07 pg/ml).
Conclusion; The present study is an evidence to support the usage of the plant which possesses several antioxidant principles for medicinal uses.
