Gartanin compounds from extract ethanol pericarp mangosteen (Garcinia mangostana linn.)

Abstract

AIM: The study aimed to isolate and identification secondary metabolite from pericarp Garcinia mangostana Linn. METHODS: The first step of this research was maceration of sample using alcohol 70% solvent. The separation and purification of compounds using Vacuum Liquid Chromatography (VLC), Radial Chromatography (RC). The purity of isolate was analyzed by thin layer chromatography (TLC) and melting point. Compounds identified using spectroscopi IR, NMR-1D (1H, 13C-NMR and DEPT) and 2-D NMR (HMQC and HMBC). RESULTS: The compound has melting point at 165-167°C. The result showed isolate was gartanin. CONCLUSION: The secondary metabolite found in pericarp Garcinia mangostana Linn. is gartanin.
