Abstract
Quercetin-3-monoarabinoside (C20H13O11) was prepd. from the diuretically active plant. The name "avicularin" is suggested for this new compound. It crystallizes from 50% alcohol in bright yellow needles, m.p. 216-217[degree]. Upon reduction with Mg and HC1, the alcoholic soln. is colored purple-red. The flavone pentoside structure was established by hydrolysis to quercetin and l-arabinose, and by isolation of 3-hydroxy-5,7,3[image],4[image]-tetramethoxyflavone upon hydrolysis of the methylated glycoside.This publication has 1 reference indexed in Scilit:
