- W2941421361 abstract "In this paper, the potency of stem and leave extracts of Leea indica locallyknown as Memali from Tasik Chini, Pahang as a potent antioxidant agent had beenstudied. The antioxidant properties of three types of extracts was quantitativelyassessed by 2,2 diphenyl-1-picrylhydrazyl ( DPPH) radical scavenging activity. Theisolation of antioxidative compounds was conducted through preparative thin layerchromatography with the use of certain binary solvents. The structure determinationwas carried out using Gas Chromatography Mass Spectrometer (GCMS). Themethanol extracts from both stem and leaves exhibited highest antioxidant activitywith lowest IC50 of 24 ug/ml and 81 ug/ml respectively compared to other extracts.The stem showed stronger antioxidant activity compared to leaves part. Based onGCMS analysis, the antioxidative compounds isolated from leaves part wereproposed as 6-Hyroxy-4,4, 7a-trimethyl-5,6,7,7a-tetrahydrobenzofuran-2(4H)-one(1), 3,8,8-Trimethoxy-3-piperidyl-2,2-binaphthalene-1,1,4,4-tetrone (2), Methylstearate (3), 9,12-Octadecadienoic acid (4), Palmitic acid (5) and 9-Oxononanoicacid (6). The antioxidative compounds isolated from stem part were determined as 1-(hydroxymethyl)-1,2-ethanediyl ester (7), 9-octadecene (8) and oleic acid (9). Thisfinding can be used as scientific baseline information for the future treatment ofdiseases caused by harmful free radicals." @default.
