MICROWAVE ASSISTED EXTRACTION OF MANGIFERIN FROM MANGIFERA INDICA L.

Abstract

The aim of this work is to compare the extraction efficiencies of microwave and conventional isolation of mangiferin from Mangifera indica L. The parameters studied, which might affect the extraction efficiency were extraction time, solvent composition and microwave power. The conventional heating 21 h provided

5.23 % yield of mangiferin and by microwave heating at 210 W for 56 min, the yield was 6.868 %. Hence microwave assisted extraction has shown as the most effective technique for the isolation of mangiferin. The isolated compounds were found to be same as evidence by UV, IR, HPTLC, and ¹H NMR studies.
