General description

(−)-Epicatechin (EC) belongs to the group of flavanols and is abundantly present in cacao and cacao products.[1] The chemical structure of EC includes an oxygenated heterocycle with a 4-hydroxyl group linked with two aromatic rings.[1]

Application

(−)-Epicatechin (EC) has been used:
  • as an antioxidant to downregulate nicotinamide adenine dinucleotide phosphate hydrogen (NADPH) oxidase and improve insulin sensitivity in in vivo (high fat-fed mice) and in vitro (HepG2 cells) studies[2]
  • to study its effect on blood pressure, nitric oxide synthase (NOS) activity and anxiety-like behavior on borderline hypertensive rat (BHR) models[3]
  • to test its effect on neuronal survival in the hippocampus of middle-aged rats on swimming training, under oxidative stress[4]
  • to study its antioxidant activity in dark chocolate[5]
  • as a characteristic compound in polyphenols analysis[6]

Biochem/physiol Actions

Epicatechin enhances the skeletal muscle structure in heart failure patients and minimizes cardiometabolic risks. It can be used for treating sarcopenia. Epicatechin reduces myostatin and β-galactosidase and increases the level of markers of muscle growth.[7]

Questions

1–2 of 2 Questions  
  1. How can I determine the shelf life / expiration / retest date of this product?

    1 answer
    1. If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
      For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
      For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.

  2. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 answer
    1. Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf
