Quercetin-3-methylether dosage

Quercetin-3-methylether, also known as isorhamnetin, is a methylated form of quercetin, naturally present in certain medicinal plants such as sea buckthorn, wild garlic, and red onions. This molecule is distinguished by its improved bioavailability, better oxidative stability, and promising antioxidant and anti-inflammatory activity.

The dosage of quercetin-3-methylether is essential for:

• Standardizing plant extracts enriched with methylated flavonoids
• Validating functional claims in food supplements
• Monitor the concentration in products for cardiovascular or immune purposes

Analytical methods

The analysis is based on two reference techniques:

• HPLC-DAD: UV absorption detection, suitable for simple or standardized matrices
• LC-MS/MS: specific and sensitive quantification in complex extracts or finished products

Affected matrices

This dosage applies to various types of matrices:

• Raw or purified plant extracts
• Food supplements in the form of capsules, tablets or powders
• Innovative formulations containing methylated flavonoids (beverages, nutraceutical mixtures)
• High value-added plant-based enriched products

Industrial applications

The dosage of quercetin-3-methylether is particularly useful for:

• Manufacturers of functional flavonoid food supplements
• Phytotherapy or active nutrition laboratories
• Players in plant-based cosmetics, particularly for the formulation of antioxidant active ingredients
• R&D projects on highly assimilable forms of polyphenols
