Description

Pinoresinol is a naturally occurring lignan, a class of polyphenolic compounds found in various plants, including sesame seeds and the resin of pine trees. This compound is of significant commercial interest due to its diverse biological activities, including antioxidant, anti-inflammatory, and potential phytoestrogenic properties. It serves as a valuable reference standard for analytical testing and as a key building block or intermediate in pharmaceutical, nutraceutical, and cosmetic research and development.

Application

• Pharmaceutical Reference Standard: Used for the identification, purity testing, and quantification of pinoresinol in herbal extracts and finished drug products via HPLC, LC-MS, or other analytical methods.
• Nutraceutical & Dietary Supplement Ingredient: Incorporated into formulations for its potential health-promoting antioxidant and anti-inflammatory benefits.
• Cosmetic & Skincare Actives: Utilized in anti-aging and protective skincare products for its antioxidant properties, helping to neutralize free radicals.
• Biomedical & Life Science Research: Serves as a critical reagent in studies investigating lignan metabolism, bioactivity, and potential therapeutic applications.
• Chemical Synthesis Intermediate: Acts as a chiral building block for the synthesis of more complex natural products and novel chemical entities.
• Food & Beverage Analysis: Employed as a standard to measure lignan content in foods like sesame oil, flaxseed, and whole grains for nutritional labeling and quality control.
