title: Studies on the flavone glycosides from Fructus Kochiae.
abstract: A series of flavone glycosides were isolated from Fructus Kochiae for the first time, including two new flavone glycosides. The structures were established by interpretation of their spectroscopic data. Two new flavone glycosides are quercetin 3-O-β-d-apiofuranosyl-(1 → 2)-β-d-galactopyranosyl-7-O-β-d-glucopyranoside (1) and quercetin 3-O-α-l-rhamnopyranosyl-(1 → 6)-β-d-galactopyranosyl-7-O-β-d-sophoroside (2). The others are quercetin 7-O-β-d-glucopyranoside (3), quercetin 3-O-β-d-apiofuranosyl-(1 → 2)-β-d-galactopyranoside (4), quercetin 3-O-β-d-galactopyranosyl-7-O-β-d-glucopyranoside (5), and quercetin 7-O-β-d-sophoroside (6).
