    Studies on the lignans of Polygonum orientale.[Reference: WebLink]

    METHODS AND RESULTS:
    Three lignans were isolated from the aerial parts of Polygonum orientale L. Their structures were elucidated as arctiin (1), Lappaol B (2), orientalin (3) by means of the spectral data and chemical methods.
    CONCLUSIONS:
    Among them, 3 is a novel compound, compounds 1 and 2 were first found in this plant.
    Lappaol B Description
    Source: The roots of Gymnadenia conopsea
    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).
