    Kaempferol-3-O-glucorhamnoside Description
    Source: The herbs of Thesium chinense Turcz.
    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.

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.

    Kaempferol-3-O-glucosyl(1-2)rhamnoside from Ginkgo biloba and a reappraisal of other gluco(1-2, 1-3 and 1-4)rhamnoside structures.[Pubmed: 1368033]
    A Kaempferol-3-O-glucorhamnoside from Ginkgo biloba is defined as the 3-O-alpha-L-[ beta-D-glucopyranosyl(1-2)rhamnopyranoside] on the basis of 2D NMR evidence.
    METHODS AND RESULTS:
    Complete assignments of the 1H and 13C NMR spectra of this compound and of its known p-coumaroyl derivative are presented for the first time. The NMR distinctions of 1-2, 1-3 and 1-4 linked glucopyranosylrhamnopyranosides are discussed and indicate (i) that the 13C NMR assignments for one published gluco(1-3)rhamnoside are in need of modification, (ii) that the published structure of hordenine-O-[6-O-t-cinnamoyl-beta-glucosyl(1-4)-alpha-rhamnoside] from Selaginella doederleinii is not distinguished from the 1-3 linked glucorhamnoside structure, and (iii) that the 8-prenylkaempferol-3-O-[glucosyl(1-4)rhamnoside]-7-O-glucoside and the equivalent 4'-O-methylated xylosyl(1-4)rhamnoside from Epimedium pubescens and E. washanense, respectively, are (1-2)-linked.
