Abstract

Analysis of substances anthosianin method Genesys 20 Visible spectrophotometer is a mangosteen. Anthosianin is an antioxidant that has the ability to mengelmisi free radicals. In the experiment obtained with the optimum solvent composition of F / S is 96% ethanol (1:10), distilled water (1:10) and ethyl acetate (1:20). The optimum solvent analyzed using visible spectrophotometer Genesys 3,4,5 ph 20 in the atmosphere to determine the optimum acidic conditions. In order to obtain the most optimum conditions of acid in each solvent pH optimum is 3. This variable distinction serves to identify the type of solvent that optimum conditions with the composition of F / S are different in order to obtain the results of the analysis. The Differences in variables such as the composition of F / S and pH influence on the analysis results. Keyword : Anthosianin, Solvent, pH
