    Pinostilbenoside Description
    Source: The seeds of Vitis vinifera
    Solvent: DMSO, Pyridine, Methanol, Ethanol, 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.

    Aryloxyacetamides Derived from Resveratroloside and Pinostilbenoside[Reference: WebLink]

    METHODS AND RESULTS:
    Etherification of phenolic hydroxyl groups of resveratroloside and Pinostilbenoside (natural 3,4’,5-trihydroxystilbene derivatives) with methyl bromoacetate afforded compounds ArOCH2CO2Me, which on treatment with amines produce the corresponding ‘stilbenyl- oxyacetamides’ in good yields.

    Reaction of several resveratrol glycoside derivatives with hypochlorites in various media[Reference: WebLink]

    METHODS AND RESULTS:
    The reactions of pterostilbenoside (trans-3,5-dimethoxystilben-4′-O-β-D-glucoside) and Ar–O–Tr derivatives of resveratroloside (3,5-dihydroxystilben-4′-O-β-D-glucoside) and Pinostilbenoside (3-methoxy-5-hydroxystilben-4′-O-β-D-glucoside) with NaOCl and t-BuOCl in the presence of the stable nitroxyl radical TEMPO were studied in various media. It was found that the principal product of pterostilbenoside transformation was its 2,6-dichloroderivative, a part of which was oxidized to form 2,6-dichloropterostilbene glucuronide.
    CONCLUSIONS:
    Trityl ethers of resveratroloside and Pinostilbenoside reacted with the hypochlorites to form mixtures of products.

    Hydroxystilbenes of the inner bark of Pinus sibirica[Reference: WebLink]

    METHODS AND RESULTS:
    In addition to pinostilbene and resveratrol, two new stilbene glycosides have been isolated from the phloem ofPinus sibirica R. Mayr, and their structures have been established as 3,4′-dihydroxy-5-methoxy-stilbene 4′-β-D-glycopyranoside (Pinostilbenoside) and 3,4′,5-trihydroxystilbene 4′-β-D-glycopyranoside (resveratroloside).
