    Source: The leaves of Ehretia ovalifolia
    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.

    A new flavone derivative from Ehretia ovalifolia leaves.[Pubmed: 11534347]
    From the methylene chloride extract of Ehretia ovalifolia leaves, a new flavone derivative named ovalifolin [3-(3-methyl-1-butenyl)-6-methoxy-5,7,4'-trihydroxy flavone] has been isolated and identified together with the known flavone aglycones apigenin, luteolin and the highly methoxylated flavanol Araneosol. The structures of these metabolites have been established on the basis of chemical, chromatographic and spectral methods.
