    Description: Damulin A and Damulin B as potential activators of AMP-activated protein kinase (AMPK) from Gynostemma pentaphyllum, which may contribute to beneficial effect of G. pentaphyllum on glucose and lipid metabolism.
    Targets: AMPK
    In vitro:
    Bioorganic & Medicinal Chemistry, 2011, 19(21):6254-6260.
    New dammarane-type glucosides as potential activators of AMP-activated protein kinase (AMPK) from Gynostemma pentaphyllum.[Pubmed: 21978948]
    AMP-activated protein kinase (AMPK) is a key sensor and regulator of glucose, lipid, and energy metabolism throughout the body. Activation of AMPK improves metabolic abnormalities associated with metabolic diseases including obesity and type-2 diabetes. The oriental traditional medicinal herbal plant, Gynostemma pentaphyllum, has shown a wide range of beneficial effects on glucose and lipid metabolism.
    METHODS AND RESULTS:
    In this study, we found that G. pentaphyllum contains two novel dammarane-type saponins designated as damulin A (1), 2α,3β,12β-trihydroxydammar-20(22)-E,24-diene-3-O-[β-D-glucopyranosyl-(1→2)-β-D-glucopyranoside], and Damulin B (2), 2α,3β,12β-trihydroxydammar-20,24-diene-3-O-[β-D-glucopyranosyl-(1→2)-β-D-glucopyranoside], that strongly activate AMPK in cultured L6 myotube cells. Damulin A and Damulin B also increased β-oxidation and glucose uptake with increasing GluT4 translocation to the plasma membrane in L6 myotube cells.
    CONCLUSIONS:
    Taken together our results indicate that activation of AMPK by Damulin A and Damulin B may contribute to beneficial effect of G. pentaphyllum on glucose and lipid metabolism.
    Damulin B Description
    Source: The roots of Panax ginseng
    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.
