Viniferine dosage

Viniferine assay quantifies this interesting stilbene extracted from the vine ( Vitis vinifera ), similar to resveratrol but with distinct biological properties. Known for its antioxidant, depigmenting and lightening effects, viniferine is an increasingly sought-after active ingredient in the cosmetics and nutraceutical sectors. Its assay is essential for standardizing vine extracts, ensuring their effectiveness and promoting natural formulations incorporating this polyphenolic active ingredient.

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

YesWeLab offers viniferine analysis using high-performance liquid chromatography (HPLC-DAD) or liquid chromatography-mass spectrometry (LC-MS). These methods distinguish viniferine from other stilbenes (resveratrol, ε-viniferine, etc.) present in vine extracts.

• HPLC-DAD: used for routine quality controls, it offers reliable quantification with detection by UV absorption in the spectral ranges characteristic of polyphenols.
• LC-MS: recommended for complex matrices or cosmetic formulations, it allows 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?

The dosage of viniferine is part of a quality approach and the promotion of extracts from the vine. It allows:

• To standardize vine extracts to guarantee a constant content of active ingredient
• To verify the potential effectiveness of lightening formulas used in dermocosmetics
• To ensure the traceability of plant 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 the analysis of viniferine in a wide range of matrices, including:

• Dry or hydro-alcoholic extracts of vine
• Grape marc or vine stem powders
• Antioxidant food supplements based on vines
• Creams, serums, lotions or dermocosmetic treatments
• Concentrated or encapsulated active ingredients (liposomes, titrated extracts)

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

Areas of application

Viniferine dosage is particularly relevant for the following industries:

• Cosmetics: formulation of lightening, anti-dark spot, anti-aging or protective treatments against oxidative stress
• Nutraceuticals: food supplements based on vine polyphenols, natural antioxidants or microcirculation support
• 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 co-products: transformation of winemaking residues into active extracts with high added value

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