Opis ogólny

Catechin is produced by Cutch tree and is abundantly found in tea leaves, grape seeds, vegetables and plant-based beverages. It is a plant-derived, polyphenolic anti-oxidant[1] and acts as a plant secondary metabolite.[2]

Zastosowanie

(±)-Catechin hydrate has been used:
  • to study its modulatory effect on drug resistance in human ovarian cancer cells[3]
  • to construct the standard curve of total flavonoid content[4]
  • to study its effects on the physiological parameters of Solanum lycopersicum[5]

Działania biochem./fizjol.

Polifenolowy przeciwutleniacz. Stosowany w tradycyjnej medycynie chińskiej.
Catechin has phytotoxic properties. Racemic catechin may be used in studies on seed germination and plant invasiveness.[6] Catechin and Epigallocatechin gallate (EGCG) may be used with other polyphenol flavonoids to study their effects in oxidation and peroxidation-related processes.[1]

Questions

1–2 of 2 Questions  
  1. 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

  2. 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.
