Abstract


In continuing of chemical study research on the parts of the fruits of Mahkota dewa, we have done isolated one antioxidant compound benzophenon glycoside from n-butanol extract. Isolation and purification by column chromatography (SiO2, chloroform-methanol) and determination of chemical structure based on interpretation spectra of ultraviolet (UV), infrared (IR) and nuclear magnetic resonance 1 dimension (1H & 13C NMR), 2 dimension (1H-1H COSY, 13C-1H COSY, HMBC). Based on spectrroscopic data, the compound was identified as 6,4’,-dihidroksi-4- metoksibenzofenon-2-O-α-D glucopyranoside.

Key words: Mahkota dewa, Phaleria macrocarpa, Thymelaceae, Indonesian medicinal plant, benzophenone glycoside
