    Gnetulin Description
    Source: The herbs of Gnetum montanum
    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.

    Enzyme-promoted regioselective coupling oligomerization of isorhapontigenin towards the first synthesis of (±)-gnetulin.[Pubmed: 24569530]

    METHODS AND RESULTS:
    We report the first synthesis of a natural (±)-Gnetulin and an unnatural analogue of (±)-gnemonol M by using the regioselective oxidative coupling reactions of 5-tert-butyl-isorhapontigenin as the key step. Both the effects of different enzyme-catalyzed systems on the structures of coupling products and structural transformations of coupling products in the presence of several Lewis acids were systematically investigated.

    Bioactive stilbene dimers from Gnetum cleistostachyum.[Pubmed: 15938189]

    METHODS AND RESULTS:
    Two new stilbene dimers, named bisisorhapontigenin A (1) and cis shegansu B (2), together with gnetuhainin P (3) and Gnetulin (4), were isolated from the lianas of Gnetum cleistostachyum C. Y. Cheng. Their structures were elucidated by means of spectroscopic evidences, including UV, IR, MS, 1H NMR, 13C NMR, NOE and 2D NMR, respectively. The pharmacological activities of compounds 1, 2 and 3 also have been tested.
