|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. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20C. Generally, these will be useable for up to two weeks. 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.

|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.|

|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.|
