Isolasi Dan Karakterisasi Senyawa Flavonoid Dari Kulit Akar Tumbuhan Sukun Artocarpus Altilis (Parkinson) Fosberg

Abstract

A flavonoid compound, artonin E (1), has successfully been isolated from root leather of Artocarpus altilis (Parkinson) Fosberg grown in the village of Banjar District State Tanggamus Wonosobo regency of Lampung Province.The structure of this compound has been carefully determined by ultaviolet-visible (UV-Vis) spectroscopy, infrared (IR) spectroscopy, nuclear magnetic resonance (NMR) spectroscopy, and based on physical data. The artonin E compound was obtained as amorphous yellow crystal with m.p. 247,5-249 0 C.
