The antioxidant activity of Annona squamosa (A. squamosa) leaf was carried out using methanol extract and fractionated extract namely n-hexane, ethyl acetate and residue. The antioxidant activity of methanol extract and fractionated was performed using the 1-diphenyl-2-Pycrilhydrazil (DPPH) method. The antioxidant activity test of methanol extract and fractionated n-hexane, ethyl acetate and residue yielded IC50 of 6.87, 169.99, 31.55 and 44.75 ppm. The ethyl acetate fraction extract with IC50 31.55 ppm was performed by column chromatography using silica gel G60 as the stationary phase and n-hexane: ethyl acetate as the mobile phase. The results of column chromatography obtained 181 fractions and were combined based on the stain pattern into 4 subfractions. Antioxidant test of each subfraction showed that the ASE 3 subfraction had the strongest antioxidant activity. Furthermore, the subfraction was analyzed using Gas Chromatography Mass Spectrometry (GC-MS). According, GC-MS data analysis showed that the third subfraction contained 19 phytochemical compounds, where 3 compounds having the highest concentration, namely 4,4{\textquoteright}-((p-Phenylene)diisopropylidene) diphenol, dodecanoic acid, methyl ester and phthalic acid, isobutyl 2-methylpent-3-yl ester.

This study aims to evaluate the antioxidant and anticancer activity of secondary metabolite compounds from Myristica fragrans Houtt. (nutmeg) bark using n-hexane extract based on DPPH radical scavenging and microculture tetrazolium salt (MTT) assay. The chemical structural analysis using NMR, FTIR, and LC-MS spectroscopy confirmed and identified the structure of isolated compound namely (2E)-5(2z.4E)-hexa-2,4,-dio-zyl)-2propylcyclohexanol (C18H30O4) for the first time which is corresponding for the excellent antioxidant and anticancer activity against MCF-7 cell lines with the IC50 value of 99.76 and 10.75 ppm, respectively.
