Description

3'-Hydroxy Puerarin is a bioactive isoflavone glycoside, a key derivative of the traditional medicinal herb Pueraria lobata (Kudzu). This compound is valued for its enhanced biological activity and serves as a critical reference standard and research chemical. It is primarily utilized by researchers and manufacturers in the pharmaceutical, nutraceutical, and cosmeceutical industries for drug discovery, quality control, and the development of advanced health supplements.

Application

• Pharmaceutical Reference Standard: Used for the identification, assay, and purity testing of puerarin and related compounds in pharmaceutical formulations and raw materials.
• Biomedical Research: Serves as a key intermediate or active compound in studies investigating antioxidant, anti-inflammatory, neuroprotective, and cardioprotective mechanisms.
• Nutraceutical Development: Incorporated into advanced dietary supplements targeting metabolic health, menopausal symptoms, and liver protection due to its potent bioactivity.
• Cosmeceutical Ingredients: Used in skincare formulations for its potential anti-aging and skin-brightening properties.
• Analytical Chemistry: Employed as a high-purity calibrant in HPLC, LC-MS, and other chromatographic methods for quantitative analysis.
• Chemical Synthesis: Acts as a sophisticated starting material or intermediate for the semi-synthesis of novel isoflavone derivatives with targeted therapeutic effects.
