Description

(-)-Hydroxymatairesinol CAS NO 20268-71-7 is a specific enantiomer of hydroxymatairesinol, a naturally occurring lignan found in the Norway spruce (*Picea abies*). This compound is of significant commercial interest due to its potent biological activity as a mammalian lignan precursor, which is converted by intestinal microflora into enterolactone. It is primarily sought after by manufacturers in the nutraceutical, pharmaceutical, and functional food industries for its application in dietary supplements and research into health-promoting products.

Application

• Dietary Supplement Formulation: As a key active ingredient in capsules, tablets, and powders targeting hormonal balance and antioxidant support.
• Functional Food & Beverage Fortification: For enrichment of foods and drinks to provide lignan-based health benefits.
• Pharmaceutical Intermediate: Used in the research and development of drugs related to hormone-dependent conditions.
• Reference Standard: Serves as a high-purity analytical standard for quality control and research in laboratories.
• Cosmeceutical Ingredients: Incorporated into skincare products for its potential antioxidant and anti-aging properties.
• Academic & Clinical Research: For in vitro and in vivo studies investigating its metabolism, bioavailability, and health effects.
