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

    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.

    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.

    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.

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