Viniferine dosage

Viniferine analysis allows for the quantification of this valuable stilbene extracted from the grapevine ( Vitis vinifera ). Similar to resveratrol, it possesses distinct biological properties. Recognized for its antioxidant, depigmenting, and brightening effects, viniferine is an increasingly sought-after active ingredient in the cosmetics and nutraceutical industries. Its analysis is essential for standardizing grapevine extracts, ensuring their efficacy, and enhancing the value of natural formulations incorporating this polyphenolic compound.

Analytical techniques: HPLC-DAD and LC-MS for reliable and accurate measurement

YesWeLab offers viniferin analysis by high-performance liquid chromatography (HPLC-DAD) or by liquid chromatography coupled with mass spectrometry (LC-MS). These methods allow viniferin to be distinguished from other stilbenes (resveratrol, ε-viniferin, etc.) present in grapevine extracts.

• HPLC-DAD: used for routine quality control, it offers reliable quantification with UV absorption detection in the spectral ranges characteristic of polyphenols.
• LC-MS: recommended for complex matrices or cosmetic formulations, it allows for more sensitive and specific quantification, even in ultra-traces.

The methods can be adapted to your requirements (detection thresholds, qualitative profiles, compliance with internal standards or cosmetic regulations).

Why analyze viniferine?

Viniferine analysis is part of a quality assurance and enhancement process for extracts derived from the vine. It allows for:

• To standardize vine extracts to guarantee a consistent content of active ingredient
• To verify the potential effectiveness of skin-lightening formulas used in dermocosmetics
• To ensure the traceability of plant-based raw materials, particularly for products claiming a natural or organic origin
• To differentiate extracts enriched with viniferine from simple extracts of grape marc or resveratrol
• To create a quality file for supplements or cosmetic products exported internationally

Analyzed matrices

YesWeLab supports viniferine analysis in a wide range of matrices, including:

• Dry or hydro-alcoholic extracts of grapevine
• Grape marc or vine stem powders
• Antioxidant food supplements made from grapes
• Creams, serums, lotions or dermocosmetic treatments
• Concentrated or encapsulated active ingredients (liposomes, standardized extracts)

Depending on the complexity of the support, a specific preparation step (extraction, filtration, purification) may be implemented before chromatographic injection.

Areas of application

Viniferine measurement is particularly relevant for the following industries:

• Cosmetics: formulation of skincare products that brighten, correct dark spots, combat aging, or protect against oxidative stress
• Nutraceuticals: food supplements based on vine polyphenols, natural antioxidants, or microcirculation supports
• Cosmetic ingredients: suppliers of standardized or certified plant-based active ingredients
• Research & development: projects on the anti-melanogenic or antioxidant properties of viniferine
• Valorization of wine by-products: transformation of winemaking residues into high value-added active extracts

Laboratories specializing in phenolic compounds

YesWeLab collaborates with a network of laboratories experienced in the analysis of plant polyphenols, stilbenes, and complex extracts. These laboratories are rigorously selected based on their accreditation (ISO 17025, COFRAC, etc.), their equipment (HPLC, LC-MS), and their expertise in cosmetic and nutraceutical matrices.

We guide you to the laboratory best suited to your needs: simple assay or detailed profile, quality control or R&D project, simple matrix or complex formulation.
