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.

Biotransformation of the naturally occurring lignan (-)-arctigenin in mammalian cell lines genetically engineered for expression of single cytochrome P450 isoforms.[Pubmed: 7997474]

METHODS AND RESULTS:
V79 Chinese hamster cells genetically engineered for stable expression of single forms of rat cytochromes P450 1A1, P450 1A2, and P450 2B1, and human P450 1A2 were used to analyse the metabolism of (-)-arctigenin. Concentrations of metabolites formed in the medium were determined by TLC, HPLC, GC, and GC-MS. Only in the cell line expressing rat P450 2B1 was (-)-arctigenin metabolized to a significant extent.
CONCLUSIONS:
The lignan was converted by O-demethylation to (-)-3'-O-Demethylarctigenin.
