EXTRACTION, ISOLATION AND STRUCTURAL ELUCIDATION OF BIOACTIVE COMPOUND FROM THE LEAVES EXTRACT OF LAGERSTROEMIA PARVIFLORA

Abstract

For thousands of years, natural remedies were the only choice for the prevention and treatment of human diseases. Drug development relies heavily on natural products. Natural remedies always have small amount of bioactive natural ingredients. Today, developing effective and selective strategies for extracting and isolating those bioactive natural compounds is critical. Lagerstroemia parviflora (L. parviflora) (Lythraceae) commonly known as Landia in India and Seja in Bundelkhand; is a species widely distributed in almost all moist and dry deciduous tracts of India. In view of its wide distribution, the tree can withstand great variation in climate. The current investigation involves the isolation, structure characterization and prediction of antioxidant compounds from the leaves of L.parviflora. The leaves samples were used for the extraction of plant constituents with methanol by using maceration method. The isolated pure compounds were characterized as (2S)-5,7-dihydroxy-2-(4-hydroxyphenyl)-2,3-dihydrochromen-4-one by 1H NMR, IR and MASS spectroscopy. The pure compounds obtained from methanol extract of the selected plant species could be a good source of natural antioxidant.
