General description

Gallic acid, also known as 3,4,5-Trihydroxybenzoic acid, is a natural polyhydroxyphenolic compound commonly found in many fruits and plants, including grapes, tea, and oak bark, either in the free acid form or esterified as gallotannins and ellagitannins. Existing research suggests that this plant-derived metabolite is an astringent, a cyclooxygenase-2 (COX-2) and histone acetyltransferase inhibitor, and an apoptosis inducer with various biological activities. These activities include antioxidant, antifungal, gastroprotective, neuroprotective, cardioprotective, antimicrobial, anti-inflammatory, anti-tumor, anti-tyrosinase, and anticancer effects.

Application

Gallic acid has been used:
  • as a standard for the quantification of extractable phenolics by external calibration
  • as a standard to determine the total tannin content of oak root powder using the Folin-Ciocalteu method
  • as a phenolic acid to study it′s in vitro antiviral, antibacterial, cytotoxicity and antifungal activities

Gallic acid is a natural product derived from plant source that finds application in compound screening libraries, metabolomics, phytochemical and biochemical research.

Biochem/physiol Actions

Gallic acid is a water soluble phenolic acid present in grapes and in the leaves of many plants. Gallic acid esters, such as tannins, catechin gallates and aliphatic gallates are potent antioxidants in vitro. However, gallic acid itself also appears to have antioxidant, anticarcinogenic and antiangiogenic activity in vitro.

Features and Benefits

  • High quality compound suitable for multiple research applications
  • Compatible with HPLC and mass spectrometry techniques

    Questions

    1–4 of 4 Questions  

    1. a che temperatura in gradi celsius va essicato? la confenzione, dopo aperta, che tempo di conservazione ha?

      1 answer

      1. No specific drying temperature has been established for this product. Available literature indicates this compound may be gently dried at 40–60 °C in an vacuum or convection oven. The material may be stored at room temperature. To avoid moisture uptake following drying, storing the product desiccated is generally recommended. This compound is quite stable and not assigned an expiration or retest date. For products with no assigned expiration date, a warranty period of 1 year from the date of shipment applies.

        Please see the following link to review a publication regarding the drying conditions typical for phenolic compounds:

    2. Questo prodotto va bene per fare la curva di taratura per la determinazione dei polifenoli totali nei vini con la metodica UV- DO 280?

      1 answer

      1. Yes, this product is well suited as a reference standard for preparing calibration curves used to determine total polyphenols and tannins in wine by the UV-DO 280 method. For additional details, refer to this application note:

    3. 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.
        For more information, please refer to the Product Dating Information document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/418/501/product-dating-information-06-25-mk.pdf

    4. 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
