General tips For obtaining a higher solubility , please warm the tube at 37 ℃ and shake it in the ultrasonic bath for a while.Stock solution can be stored below -20℃ for several months.
We recommend that you prepare and use the solution on the same day. However, if the test schedule requires, the stock solutions can be prepared in advance, and the stock solution must be sealed and stored below -20℃. In general, the stock solution can be kept for several months.
Before use, we recommend that you leave the vial at room temperature for at least an hour before opening it.
About Packaging 1. The packaging of the product may be reversed during transportation, cause the high purity compounds to adhere to the neck or cap of the vial.Take the vail out of its packaging and shake gently until the compounds fall to the bottom of the vial.
2. For liquid products, please centrifuge at 500xg to gather the liquid to the bottom of the vial.
3. Try to avoid loss or contamination during the experiment.
Shipping Condition Packaging according to customer requirements(5mg, 10mg, 20mg and more). Ship via FedEx, DHL, UPS, EMS or other couriers with RT, or blue ice upon request.

Effect of (+)-catechin hydrate on oxidative stress induced by high sucrose and high fat diet in male Wistar rats.[Pubmed: 24266106]

Indian J Exp Biol. 2013 Oct;51(10):823-7.


METHODS AND RESULTS:
Increased lipid peroxidation and reduced glutathione levels in liver of rats fed high sucrose high fat (HSHF) diet were normalized by concomitant administration of (+)-Catechin hydrate. Plasma non-enzymatic antioxidants viz. alpha-tocopherol, ascorbic acid and total thiols decrease were also significantly less in rats administered with (+)-Catechin hydrate concomitantly with HSHF diet. Thus the present results indicate that (+)-Catechin hydrate has antioxidant activity and is effective in reducing oxidative stress.
CONCLUSIONS:
The study is of clinical importance as oxidative stress is known to be the cause of many clinical manifestations viz. cancer, Parkinson's disease, atherosclerosis, heart failure, myocardial infarction and many other diseases.

Electrochemical, Thermodynamic and Adsorption Studies of (+)-Catechin Hydrate as Natural Mild Steel Corrosion Inhibitor in 1 M HCl[Reference: WebLink]

Int. J. Electrochem.Sc., 2011, 6(2011):1396-414.

The inhibiting action of (+)-Catechin hydrate on the corrosion of mild steel in hydrochloric acid has been studied.
METHODS AND RESULTS:
The results from weight loss, Tafel polarization and electrochemical impedance measurements consistently identify (+)-Catechin hydrates as a good inhibitor. Polarization curves indicate that (+)-Catechin hydrate act as mixed type inhibitor with predominant inhibition at anodic site. Impedance spectroscopy revealed that the corrosion of mild steel in hydrochloric solution was influenced to some extent by charge transfer. The inhibition efficiencies (IE %) of (+)-Catechin hydrate was decreased exponentially with the temperatures. Surface analyses via scanning electron microscope (SEM) show a significant morphological improvement on the mild steel surface in addition of (+)-Catechin hydrate.
CONCLUSIONS:
The inhibitive action of (+)-Catechin hydrate follows the Langmuir adsorption model.
