Pinoresinol dosage

Pinoresinol analysis quantifies this non-glycosylated lignan found in many plants and vegetable oils, including olive oil , flaxseed , sesame , and thyme .
Pinoresinol is known for its and phytoestrogenic properties , making it a key marker in assessing the nutritional and functional quality of plant-based and nutraceutical products.
This analysis allows for the standardization of natural extracts , the validation of health claims , and the assurance of regulatory compliance for finished products.

Analytical methods

high-precision chromatographic methods :

• HPLC-DAD (high-performance liquid chromatography) : separation and quantification of pinoresinol in complex plant matrices,
• LC-MS/MS (liquid chromatography coupled with mass spectrometry) : specific identification and detection at low concentrations,
• ISO 17025 recommendations , European Pharmacopoeia or internal standards.

These approaches guarantee excellent sensitivity and total traceability of results, even in matrices rich in polyphenols.

Industrial applications

Pinoresinol dosage is particularly relevant for:

• The characterization of vegetable oils (olive, flax, sesame) within the framework of quality control,
• The standardization of plant extracts used in food supplements or natural cosmetics ,
• The evaluation of the antioxidant and hormonal potential of nutraceutical products,
• Studies of stability or transformation during extraction or refining processes.

Matrices analyzed

• Vegetable oils and food products rich in lignans
• Extracts of medicinal or aromatic plants
• Dietary supplements based on natural antioxidants
• Cosmetics based on plant polyphenols

Further analyses recommended

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

• Sesamin dosage : a lignan complementary to pinoresinol in sesame seeds,
• Dosage of secoisolariciresinol : another major lignan in flax and plant products,
• Total flavonoid content : an overall indicator of antioxidant potential.
• Tyrosol dosage : antioxidant marker of virgin olive oils.
