AN INVESTIGATION ON EXTRACTION OF COMPONENTS FROM MANGO SEED KERNELS USING DIFFERENT SOLVENTS

Abstract

The kernels obtained from the seeds of Mangifera indica were powdered, extracted using different solvents such
as hydroalcoholic, chloroform, n-hexane, ethyl acetate.Actually, different extraction procedures like Soxhlet
extraction, maceration were employed for the extraction of components from Mangifera indica seed kernels.
The above obtained extracts were studied for the phytochemical, proximate analysis and mineral composition.
The preliminary phytochemical tests revealed the presence of Cardiac glycoside, alkaloids, flavonoids, phenols,
coumarins, terpenes etc.,Most of the components were found in methanolic extract and ethyl acetate extracts.
The proximate compositionrevealed moisture content (4.5%),crude protein(4.59%), ash(2.3%),crude fibre
(0.39%), carbohydrate (79.24%). The mineral composition was found to be sodium (26.1ppm), potassium
(121.1ppm), calcium (0.31ppm), magnesium (0.49ppm). These seed kernels may be considered as a good source
of nutrition. The presence of few components may serve in mitigating some diseases. Some studies have proven
this and evaluated the compound responsible for this. Most of the components are found inhexane and aqueous
methanolic extracts than the chloroform and ethyl acetate extracts.
