    8,9-Didehydro-7-hydroxydolichodial Description
    Source: The herbs of Patrinia villosa.
    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.

    Chemical Constituents from Patrinia villosa[Reference: WebLink]
    To investigate the chemical constituents from the ethanol extract of Patrinia villosa. Methods: Various column chromatographic methods including silica gel and Sephadex LH-20 were used for the isolation and purification. Chemical structures were elucidated on the basis of spectroscopic analysis. Results: Six compounds were isolated and identified as 8,9-Didehydro-7-hydroxydolichodial-1-dimethyl acetal( 1),8,9-Didehydro-7-hydroxydolichodial( 2),ursolic acid( 3),3-O-methylquercetin( 4),luteolin( 5) and kaempferol-3-O-arabinoside( 6). Conclusion: Compound 1 is a new secoiridoid,and compounds 2,4,6 are isolated from the Patrinia genus for the first time.
