NAT-O2 ANALYSIS OF NON POLAR FRACTION FROM MAHKOTA DEWA (PHALERIA MACROCARPA (SCHEFF.) BOERL.) FRUIT WITH GAS CHROMATOGRAPHY-MASS SPECTROSCOPY 1 Susilawati, Sabirin Matsjeh, Harno Dwi Pranowo and Chairil Anwar 2 2 2 Student of Doctoral Program, Department of Chemistry, Faculty of Mathematics and Natural Sciences, Gadjah Mada University, Sekip Utara, Yogyakarta, Indonesia 2 Department of Chemistry, Faculty of Mathematics and Natural Sciences, Gadjah Mada University, Sekip Utara, Yogyakarta, Indonesia E-mail: [email protected] Analysis of n-hexane fraction from mahkota dewa fruit had been carried out by using GC -MS. The result of GC separation revealed that n-hexane fraction contains 27 components but only 6 components of fatty acid ester were analysed. Based on the GC-MS library prediction, peak 7 (t R =17 and 4 min) was identified as 2-propenoic acid 3 phenil methyl ester (methyl cinnamate) whereas peak 20 and 23 (t R = 24 and 26.6 min) were known as hexadecanoic acid methyl ester (m ethyl palmitate) and cyclopentanetridecanoic acid methyl ester, respectively. Unfortunately, peak 14, 24 dan 27 were unidentified. Analysis fragmentations were carried out for the 3 compounds that have been successfully identified. 1 165 23rd-25th June 2010 3rd ICYC 2010 Universiti Sains Malaysia NAT-O3 ISOFLAVANOIDS FROM THE ROOT OF SESBANIA GRANDIFLORA (L.)
