|To investigate the chemical constituents of Viola yedoensis and their antioxidant activity.|
METHODS AND RESULTS:
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.
Compound 2 was reported from Viola yedoensis for the first time,and compounds 1 and 8 were the first time to be isolated from the genus Viola.
Apigenin 6-C-alpha-L-arabinopyranosyl-8-C-beta-D-xylopyranoside Description
||The whole plants of Viola yedoensis.
||Chloroform, Dichloromethane, Ethyl Acetate, DMSO, Acetone, etc.
||Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months(2-8C).
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20C. Generally, these will be useable for up to two weeks. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
Need more advice on solubility, usage and handling? Please email to: firstname.lastname@example.org
||The packaging of the product may have turned upside down during transportation, resulting in the natural compounds adhering to the neck or cap of the vial. take the vial out of its packaging and gently shake to let the compounds fall to the bottom of the vial. for liquid products, centrifuge at 200-500 RPM to gather the liquid at the bottom of the vial. try to avoid loss or contamination during handling.

|Flavone C-glycosides from Viola yedoensis MAKINO.[Pubmed: 14519932]|
METHODS AND RESULTS:
A new flavone C-glycoside, apigenin 6-C-alpha-L-arabinopyranosyl-8-C-beta-L-arabinopyranoside, has been isolated from Viola yedoensis together with the known compounds, apigenin 6,8-di-C-alpha-L-arabinopyranoside, apigenin 6-C-alpha-L-arabinopyranosyl-8-C-beta-D-glucopyranoside (isoschaftoside), apigenin 6-C-beta-D-glucopyranosyl-8-C-alpha-L-arabinopyranoside (schaftoside), apigenin 6-C-beta-D-glucopyranosyl-8-C-beta-L-arabinopyranoside (neoschaftoside), apigenin 6,8-di-C-beta-D-glucopyranoside (vicenin-2), Apigenin 6-C-alpha-L-arabinopyranosyl-8-C-beta-D-xylopyranoside, apigenin 6-C-beta-D-xylopyranosyl-8-C-alpha-L-arabinopyranoside, luteolin 6-C-beta-D-glucopyranoside (isoorientin) and luteolin 6-C-alpha-L-arabinopyranosyl-8-C-beta-D-glucopyranoside (isocarlinoside).
The structures were determined by spectroscopic methods and new or revised (1)H- and (13)C-NMR spectral assignments are proposed for some compounds.
