영문 초록

For the investigation of medicinal resources in Hydrocotyle species, the studies were conducted to evaluate the pharmaco-constituents in Hydrocotyle japonica MAKINO (Umbelliferae), which is used as folk medicine in Korea. From the methyl alcohol extract of the whole plant, isorhamnetin-3-O-beta-D-galactoside (C22H22012.1/3H20, bright yellow needle crystal, mp 247-248oC, [alpha]D28o=52.27o in pyridine), one of three flavonol substances in extrat, was isolated and identified by physicochemical properties and spectroscopic evidences (UV, IR, NMR and MS etc.,) in comparison with authentic sample. This flavonoid was appeared from Hydrocotyle japonica MAKINO through phytochenical approaches at the outset.
