    Biological Activity
    Description: Apigenin 6-C-alpha-L-arabinopyranosyl-8-C-beta-D-xylopyranoside is a natural product from Viola yedoensis.
    In vitro:
    Chinese Journal of Experimental Traditional Medical Formulae, 2013, 19(21):77-81.
    Chemical Constituents of Viola yedoensis and Their Antioxidant Activity.[Reference: WebLink]
    To investigate the chemical constituents of Viola yedoensis and their antioxidant activity.
    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
    Source: The whole plants of Viola yedoensis.
    Solvent: Chloroform, Dichloromethane, Ethyl Acetate, DMSO, Acetone, etc.
    Storage: 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.

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: service@chemfaces.com

    After receiving: 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.
