Apigenin6-C-α-L-arabinopyranosyl-8-C-β-D-xylopyranoside-product

Description	Apigenin 6-C-alpha-L-arabinopyranosyl-8-C-beta-D-xylopyranoside is a natural product from Viola yedoensis.
In vitro	A systematic isolation was performed by various column chromatography with the n-butanol fraction of the ethanolic extract of the herb. Eleven compounds were isolated and identified as kaempferol-3-O-β-D-sophorosyl-7-O-α±-L-rhamnopyrano-side(1),kaempferol-3,7-di-O-α±-L-rhamnopyranoside(2),apigenin-6,8-di-C-β-D-glucopyranoside(3),adenosine(4),esculetin(5),Apigenin 6-C-alpha-L-arabinopyranosyl-8-C-beta-D-xylopyranoside(6),apigenin-6-C-β-D-glucopyranosyl-8-C-α±-L-arabinopyranoside(7),apigenin-6-C-β-D-glucopyranosyl-8-C-β-D-xylopyranoside(8),apigenin-6,8-di-C-α±-L-arabinopyranoside(9),apigenin-6-C-β-D-glucopyranosyl-8-C-β-L-arabinopyranoside(10) and kaempferol-3-O-β-D-glucopyranosyl-7-O-α±-L-rhamnopyranoside(11),respectively. All compounds were evaluated for antioxidant capacity against DPPH radicals,and compounds 1-5 and 11 showed antioxidant activities.
