Description

Theaflavin 3'-o-Gallate is a specific polyphenolic compound belonging to the theaflavin class, which are key pigments responsible for the color and astringency of black tea. This compound matters for its potent biological activities, including significant antioxidant, anti-inflammatory, and potential chemopreventive properties. It is needed by researchers in the nutraceutical, pharmaceutical, and cosmetic industries for product development and by manufacturers of high-value functional food and dietary supplement ingredients.

Application

• Nutraceutical & Dietary Supplements: A core ingredient in formulations targeting oxidative stress, metabolic health, and general wellness due to its high antioxidant capacity.
• Pharmaceutical Research: Investigated in preclinical studies for its potential anti-cancer, cardioprotective, and neuroprotective effects.
• Cosmetics & Skincare: Incorporated into anti-aging serums, creams, and lotions for its ability to neutralize free radicals and protect skin from environmental damage.
• Functional Food & Beverages: Used to fortify health drinks, teas, and food products to enhance their bioactive profile.
• Analytical Reference Standard: Serves as a high-purity standard for quality control and research in laboratories analyzing tea extracts and polyphenol content.
• Biochemical Research: A key tool for studying signal transduction pathways, enzyme inhibition, and the mechanisms of polyphenol bioactivity.
