|Pallidol, a resveratrol dimer from red wine, is a selective singlet oxygen quencher.[Pubmed: 19101516]|
|Pallidol is a naturally occurring resveratrol dimer from red wine with antioxidant and antifungal activities. |
METHODS AND RESULTS:
In this report, with the use of the EPR spin-trapping technique, the scavenging and quenching effects of Pallidol on reactive oxygen species (ROS) were investigated. The results demonstrated that Pallidol showed strong quenching effects on singlet oxygen at very low concentrations, but it was ineffective to scavenge hydroxyl radicals or superoxide anions. Further kinetic study revealed that the reaction of Pallidol with singlet oxygen had an extremely high rate constant (k(a)=1.71x10(10)).
Therefore, Pallidol is a potent and selective singlet oxygen quencher in aqueous systems. It may be used in singlet oxygen-mediated diseases as a pharmacological agent, which may contribute to the health beneficial effects of red wine.

||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.

||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.
