Pinoresinol diglucoside dosage

Pinoresinol diglucoside assay quantifies this glycosylated lignan naturally present in several plants and vegetable oils , including virgin olive oil .
A bioactive compound with high antioxidant power , it plays a role in cellular protection against oxidative stress and contributes to the cardiovascular benefits associated with the consumption of olive oil and plant extracts rich in polyphenols.
Pinoresinol diglucoside analysis is therefore essential for standardizing plant products , ensuring the consistency of the polyphenolic profile and validating health claims .

Analytical methods

The identification and quantification of pinoresinol diglucoside is carried out by high sensitivity chromatographic :

• HPLC-DAD (high performance liquid chromatography) : allows separation and precise 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 compliant with ISO 17025 , European Pharmacopoeia or methods validated internally by partner laboratories.

Industrial applications

Pinoresinol diglucoside dosage is particularly useful in:

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

Analyzed matrices

• Vegetable oils and food products rich in polyphenols
• Medicinal plant extracts
• Antioxidant food supplements
• Cosmetic products based on natural compounds

Further analyses recommended

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

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