Secondary Metabolites Analysis of Methanol Extract of Surian (Toona sureni (Bl.) Merr) Leaf as Antioxidant Potential.

Abstract

Secondary Metabolites Analysis of Methanol Extract of Surian (Toona sureni (Bl.) Merr) Leaf as AntioxidantPotential. The study of performed secondary metabolites from the methanol extract of Surian (Toona sureni (Bl.) Merr)leaves have been done by thin-layer chromatography (TLC) method. The result showed that methanol extract of Surianleaves consist of alkaloid, flavonoid, polyphenol and terpenoid. All of them positively have the ability to scavenge 2,2-diphenyl-1-picrylhydrazyl (DPPH). It has IC50 (4.80) are smaller than the ascorbat acid standard (IC50 = 9.23).
