Abstract

Buah Makasar (Brucea javanica Merrill)is a wild ornamental plant and one of the traditional medicine plants. Isolation andpurification of ethyl acetate extract of B.javanica using silica gel column chromatography with ethyl acetatem-hexane as a mobile phase gradually obtained a pure compound as yellow crystals. It was identified by using infrared spectrophotometer (IR), LC-MS (liquid chromatography mass spectrometer) and ID- and 2D-NMR (nuclear magnetic resonance), compound a identified as 6-hydroxy-2-(3,4,5-trihydroxyphenyl}-4H-chromen-4-one, a flavones compound with molecular formula Cl5HI006 and molecular weight of 287.18 m/z.Keywords: Brucea javanica Merrill, buah makasar, flavones,6-hydroxy-2-(3,4,5-trihydroxyphenyl)-4H-chromen-4-one

Abstract

The preparation of Brucea leaves have been done for specific parameters and non specific parameter laboratory worb refers to TheNational Agency of Drug and Food Control Regulation for extract quality control. The result for specific extract parameters  were the rendement of extraction is 28%, the values of water- extractive and ethanol-extractive are 11.49% and 9.41%,  respectively. The result of determination of the non specific  parameters of the extract are; loss on drying is 18.95%, the  water content is 15.06%, the total ashes is 16.12%. and the  level of ashes not dissolved in acid is 11.14%. The analysis of chemical compound shows that the extract containedflavonoid,  tannin, and glycoside. For the quantitative control has been measured the level of totalflavonoid wherethe result is 9.901%Keywords : Preparation, Brucea; Specific parameter, non specificparameter, extract
