• Schult. and Schult. f. (Asparagaceae) grows in India, Indonesia, Sri Lanka, and tropical Africa. Even though the plant has been traditionally used for the treatment of many ailments, the antioxidant and antiproliferative activities of methanol extract and its fractions have not yet been explored. Quantitative estimation of phenols and different antioxidant assays were performed using standard methods. Anti-proliferative effect of the extract and fractions were evaluated in HCT-116, HeLa, MCF-7, HepG2, and A-549 cancer cell lines by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) and sulforhodamine B (SRB) assay methods. High-performance liquid chromatography (HPLC) and high-performance thin layer chromatography (HPTLC) fingerprint profiling were carried out for extract and different fractions. Significant antioxidant and anti-proliferate activity were detected in ethyl acetate fraction. Ethyl acetate fraction showed prominent scavenging activity in 1,1-diphenyl-2-picrylhydrazyl, 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt, and nitric oxide antioxidant assays with an concentration yielding 50% inhibition (IC ) 15.33 ± 1.45, 45.3 ± 1.93 and 48.43 ± 0.46 mg/ml, respectively. Cytotoxicity of ethyl acetate fraction was the highest among other fractions against HCT-116, HeLa, and MCF-7cancer cell lines with IC values 16.55 ± 1.28, 12.38 ± 1.36, and 8.03 ± 1.9 μg/ml, respectively, by MTT assay and 15.57 ± 0.70, 13.19 ± 0.49, and 10.34 ± 0.9 μg/ml, respectively, by SRB assay. The presence of gallic acid in the ethyl acetate fraction of rhizomes was confirmed by HPLC and HPTLC analysis. Results suggested that ethyl acetate fraction exhibited effective antioxidant and antiproliferative activities. The phenolic compounds identified in ethyl acetate fraction could be responsible for the activities. has been selected for antioxidant and cytotoxicity screeningEthyl acetate fraction of methanol extract of exhibited effective antioxidant and antiproliferative activitiesThe activity of ethyl acetate fraction may be due to the presence of phenolic compound which is identified by high-performance liquid chromatography and high-performance thin layer chromatography techniques. %: Percent, ºC: Celsius, mg: Microgram, ml-Microlitre, ANOVA: Analysis of variance, DMSO: Dimethyl sulfoxide, g: Grams, IC50: Concentration yielding 50% inhibition, Kg: Kilogram, mg: Milligram, min: Minutes, ml: Milliliter, HPLC: High-performance liquid chromatography, HPTLC: High-performance thin layer chromatography, DPPH: 1,1-diphenyl-2-picrylhydrazyl, ABTS: 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt, MTT: 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide, GAE: Gallic acid equivalents, SRME: Methanol extract of , ROS: Reactive oxygen species, SRPE: Petroleum ether fraction of , SREA: Ethyl acetate fraction of , SRAQ: Aqueous fraction of , DMEM: Dulbecco's Minimum Essential Medium, FBS: Fetal bovine serum, OD: Optical density, TPC: Total phenolic content, SRBU: Butanol fraction of .
