    Xanthopurpurin Description
    Source: The roots of Rubia cordifolia
    Biological Activity or Inhibitors: 1. Xanthopurpurin may can effectively inhibit rotavirus multiplication by promoting virus-induced apoptosis in MA-104 cells.
    2. Xanthopurpurin shows mainly strong inhibition of collagen-induced platelet aggregation.
    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. 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: 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.

    In vitro Antiviral Activity of Rubia cordifolia Aerial Part Extract against Rotavirus.[Pubmed: 27679574]
    The major compounds postulated to exhibit this activity were isolated from the aqueous herbal extract and identified to be compounds Xanthopurpurin and Vanillic Acid. This study showed that RCAP extract effectively inhibited rotavirus multiplication by promoting virus-induced apoptosis in MA-104 cells.

    Antiplatelet constituents of formosan Rubia akane.[Pubmed: 8176404]
    A known steroid, in addition to triterpenoids, anthraquinones, naphthalenes and a new anthraquinone glycoside, Xanthopurpurin 3-O-beta-D-glucoside, were isolated from the roots of Rubia akane grown in Taiwan. Mollugin, a naphthohydroquinone, showed strong inhibition of arachidonic acid (AA)-induced and collagen-induced platelet aggregation. In contrast, 2-methyl-1,3,6-trihydroxyl-9,10-anthraquinone, Xanthopurpurin 3-O-beta-D-glucoside, and Xanthopurpurin showed mainly strong inhibition of collagen-induced platelet aggregation.
