    Sideritoflavone Description
    Source:
    Biological Activity or Inhibitors:
    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.

    5,7-Dihydroxy-3-(4-hydroxy-3,5-dimethoxybenzyl)-6,8-dimethylchroman-4-one[Reference: WebLink]
    Nine compounds were isolated from an AcOEt extract of Ophiopogonis Tuber and showed a strong cytotoxic activity on HeLa-S_3 cell. Two of them were new compounds and their structures were established as 7, 8-dihydroxy-6-methyl-3-(2, 4-dimethoxy-benzyl) chroman-4-one and 5, 7-dihydroxy-6, 8-dimethyl-3-(4-hydroxy-3, 5-dimethoxy-benzyl) chroman-4-one(5,7-Dihydroxy-3-(4-hydroxy-3,5-dimethoxybenzyl)-6,8-dimethylchroman-4-one) by their ^1H-NMR, ^<13>C-NMR and HR-MS spectra. The original plant of the crude drug used in this experiment was identified as Ophiopogon chekiangensis by microscopic examination.
