Flavonoid Glycosides from Picris koreana
摘要
The two flavonoids isoetin-4′-O-α-L-arabinopyranosyl-5′-O-β-D-glucopyranoside (1) and luteolin-7-O-β-D-glucopyranoside (2), which were identified using NMR spectroscopy, were isolated from the aerial part of Picris koreana (Kitam.) Vorosch. Flavonoid 1 was a new and previously unreported compound.
