Isolation of Mangiferin from Different Varieties of Mangifera Indica Dried Leaves

Abstract

The kinetics and structural changes in the solid were studied for solid-liquid extraction from plants. Soxhlet extraction technique has been developed to extract Mangiferin from Mangifera Indica Leaves. This research aims to develop for the first time the process of mangiferin extraction from the leaves of two mango varieties, i.e. Kesar and Hapoos by using soxhlet extraction with Methanol as an extracting solvent. The study involved sampling, storage, preparation, extraction and analysis for Mangiferin was done by High Pressure Liquid Chromatography. The results found that Hapoos gave the highest yield of mangiferin as compared to Kesar. Extraction of Mangiferin from Mangifera Indica Leaves was carried out in a series of solvents methanol, ethanol and acetone. Maximum yield of extraction of Mangiferin was estimated in Methanol on the basis of solubility and therefore was used to investigate influence of operating parameter like particle size and temperature on the recovery in a stirred batch extractor. Particle size of 0.1-0.3 mm, 70 0 C temperature and methanol as a solvent were found to be the optimum parameters for the extraction of Mangiferin from the batch experimental work. Effective intraparticle diffusivity of Mangiferin in methanol was estimated using Wilky-Chang equation and activation energy of diffusion is also estimated by using Arrhenius equation.
