Pinoresinol diglucoside dosage

Pinoresinol diglucoside analysis quantifies this glycosylated lignan, naturally present in several plants and vegetable oils , particularly virgin olive oil .
A bioactive compound with strong antioxidant properties , it plays a role in protecting cells against oxidative stress and contributes to the cardiovascular benefits associated with consuming olive oil and plant extracts rich in polyphenols.
Pinoresinol diglucoside analysis is therefore essential for standardizing plant products , ensuring the consistency of the polyphenol profile , and validating health claims .

Analytical methods

highly sensitive chromatographic methods :

• HPLC-DAD (high-performance liquid chromatography) : enables precise separation and quantification in complex matrices,
• LC-MS/MS (liquid chromatography coupled with tandem mass spectrometry) : used for specific detection and structural confirmation, even at low concentrations.

These analyses are carried out according to protocols conforming to the requirements of ISO 17025 , European Pharmacopoeia or methods validated internally by partner laboratories.

Industrial applications

Pinoresinol diglucoside measurement is particularly useful in:

• control of vegetable oils (olive oil, flaxseed oil, sesame oil),
• The standardization of plant extracts used in nutraceuticals , natural cosmetics or functional foods ,
• Studies on the stability and transformation of lignans during refining or extraction,
• Characterization of the polyphenol profile in high value-added products.

Matrices analyzed

• Vegetable oils and food products rich in polyphenols
• Extracts of medicinal plants
• Antioxidant dietary supplements
• Cosmetic products based on natural compounds

Further analyses recommended

For a complete view of the lignan and polyphenol profile , YesWeLab recommends:

• Pinoresinol assay : non-glycosylated lignan precursor of diglucoside,
• Sesamin dosage : another lignan present in sesame seeds,
• Dosage of tyrosol and hydroxytyrosol : major antioxidants in olive oils,
• Total polyphenol content : overall indicator of the antioxidant richness of extracts.
