Gnaphalin assay

Gnaphaliin is a flavonol-type flavonoid, isolated primarily from plants of the genus Gnaphalium , but also present in certain medicinal species used in herbal medicine. It is recognized for its antioxidant, anti-inflammatory, and antimicrobial properties, and serves as a quality marker in plant extracts intended for nutraceutical uses.

Gnaphaliin measurement is essential in the following contexts:

• Standardization of botanical extracts, guaranteeing a constant content of active compounds.
• Evaluation of the quality of plant-based food supplements rich in flavonoids.
• Control of functional claims regarding antioxidant or protective properties.
• Monitoring the stability of extracts during formulation or preservation studies.

Available analytical methods

• HPLC-DAD: liquid chromatography with UV absorption detection, suitable for simple extracts and those with low levels of interfering substances.
• LC-MS/MS: a more specific and sensitive method, allowing the quantification of gnaphaliin in complex matrices (multicomponent extracts, finished products).

Compatible matrices

• Hydroalcoholic or dry extracts of plants of the genus Gnaphalium
• Dietary supplements made from medicinal plants (capsules, powders, tablets)
• Infusions, herbal teas or liquid plant-based formulations
• Plant-based raw materials obtained from harvesting or cultivation

Industrial applications of dosing

• Formulation of food supplements with antioxidant or immunomodulatory properties
• Development of standardized phytotherapeutic products
• Validation of the botanical origin and authenticity of the raw materials
• Quality control in plant production chains
