Isolation and characterization of homoisoflavonoids from Scilla persica HAUSSKN

Abstract

Medicinal plants have many traditional claims including the treatment of ailments of infectious origin. In the evaluation of traditional claims, scientific research is extremely important. In this study, five homoisoflavonoids named 3-(4’-hydroxybenzylidene)-5,7-dihydroxy-6-methoxychroman- 4-one(Autumnalin),3-(4’-hydroxybenzyl)-5,7-dihydroxy-6-methoxychroman-4-one (3,9-dihydroautumnalin), 3-(3’,4’-dihydroxybenzyl)-5,8-dihydroxy-7-methoxychroman-4-one,3-(3’,4’- dihydroxybenzylidene)-5,8-dihydroxy-7-methoxychroman-4-one and 3-(3’,4’-dihydroxybenzylidene)- 5,7-dihydroxy-6-methoxychroman-4-one, were isolated from the bulbs of the plant Scilla persica HAUSSKN. Their structures were established on the basis of extensive spectroscopic analyses such as NMR, MS, IR and UV.
