Isolation and Structure Elucidation of Isoquercitrin from the Whole Herb of Hygrophila salicifolia (Acanthaceae)

Abstract

There are a large number of traditional plants, their extracts and phytoconstituents presently used in modern medicine. There is a worldwide majority of the population that still relies on plants as a source of medicine. One of the medicinally useful plant is Hygrophila salicifolia. Hygrophila salicifolia is an erect herb (family: Acanthaceae). It has many medicinal uses like diuretic and anti inflammatory in traditional systems of medicine. Till date no data available for its Phytoconstituents therefore isolation of phytoconstituent was done from methanolic extract of Hygrophila salicifolia. Flavonoid was isolated for the first time from a Hygrophila salicifolia (Acanthaceae). Its structure was established on the basis of its spectroscopic data such as UV, IR, Mass, NMR, Melting point, HPTLC and laterally confirmed as Isoquercitrin.
