Isi artikelSynthesis of Tetrahydrohexagamavunon-5 (THHGV-5) and Tetrahydrohexagamavunone-7 (THHGV-7) were prepared by catalytic hydrogenation reaction on Hexagamavunon-5 (HGV-5) and Hexagamavunone-7 (HGV-7) by using gas H2 as source of hydrogen gas, Pd/C 10 % as metal catalyst and methanol as solvent at room temperature. According to previous study, Pd/C catalyst is more specific than other metal catalyst to reduce a,ß-unsaturated double bond without reduction of its carbonyl functional group. The products were characterized by IR Spectroscopy, Gas Chromatography-Mass Spectroscopy (GCMS), 1D-NMR (1H-NMR and 13C-NMR) and 2D-NMR (1H-13C HMQC) Spectroscopy to determine the product structure molecules. According to the data of IR, GC-MS, 1H-NMR, 13C-NMR and 1H-13C HMQC spectra, the products are THHGV-5 and THHGV-7 as white crystalline powders.
