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.

    Protocol
    Structure Identification:
    Chinese Journal of Natural Medicines, 2011, 9(6):410-413.
    Two New Compounds from the Roots of Rheum palmatum.[Reference: WebLink]
    To study the constituents of Rheum palmatum.
    METHODS AND RESULTS:
    Chromatographic separations of silica gel and polyamide were used. All the structures were elucidated on the basis of chemical and spectroscopic analysis. Nine compounds were isolated and their structure were identified as 2, 5-dimethyl-6, 8-dihydroxy-chromone (1), 1-methyl-2, 8-dihydroxy- 3-carboxy −9, 10-anthraquinone (2), citreorosein (3), 4-(4-hydroxyphenyl)-2-butanone (4), 4-(4-hydroxyphenyl)-2-butanone-4′-O-β-D- (2″-galloyl-6″-O-p-coumaroyl)-glucopyranoside (5), trans-3, 5, 4′-trihydroxystilbene-4′-O-β-D-(6″-galloyl)-glucopyranoside (6), 4-(4- hydroxyphenyl)-2-butanone-4′-O-β-D-(6″-O-cinnamoyl)-glucopyranoside (7), 4-(4-hydroxyphenyl)-2-butanone-4′-O-β-D-(6″-O-p-coumaroyl)-glucopyranoside (8), trans-3, 5, 4′-trihydroxystilbene-4′-O-β-D-glucopyranoside (9).
    CONCLUSIONS:
    Compounds 1 and 2 were newly isolated from Rheum palmatum.
