Dosage of sinapic acid or sinapinic acid

Sinapic acid (or sinapinic acid) is a phenolic acid belonging to the hydroxycinnamic family, naturally present in oilseeds such as rapeseed, mustard, and sunflower, as well as in certain fruits, vegetables, and cereals. It plays an important role in defending plants against oxidative stress and contributes to their biochemical stability.

From a functional perspective, sinapic acid is recognized for its potent antioxidant properties, as well as its anti-inflammatory, neuroprotective, and antimicrobial effects. These activities make it a molecule of interest for the formulation of dietary supplements, plant extracts for health purposes, and also anti-aging or protective cosmetic products.

Why measure sinapic acid?

The determination of sinapic acid is a valuable tool in several industrial and research contexts. It allows, in particular, the following:

• Standardize plant extracts rich in phenolic compounds;
• Evaluate the potential antioxidant activity of nutraceutical formulations;
• Control the stability and quality of natural cosmetics;
• Check for the presence or concentration of this acid in oilseeds or functional foods;
• Meeting labelling, traceability or regulatory compliance requirements in health nutrition.

The precise quantification of sinapic acid also makes it possible to support functional claims or to guide the selection of botanical extracts according to their polyphenolic profile.

Available analytical methods

At YesWeLab, sinapic acid analysis relies on advanced chromatographic techniques, adapted to the requirements of sensitivity and reproducibility:

• HPLC-DAD (high-performance liquid chromatography with UV-Vis detection): reference method for the separation and quantification of phenolic compounds in complex extracts;
• LC-MS/MS (liquid chromatography coupled with tandem mass spectrometry): ideal for complex matrices, with very low detection limits and high specificity.

The methods are validated and standardized, carried out in partner laboratories certified to ISO 17025 and/or accredited by COFRAC, guaranteeing complete traceability of results.

Matrices analyzed

The sinapic acid assay services offered by YesWeLab cover a wide variety of matrices, including:

• Extracts of rapeseed, mustard, sunflower and other oilseeds;
• Dietary supplements based on plants or vegetable oils;
• Natural cosmetic products, antioxidant serums, anti-aging treatments;
• Nutritional formulations enriched with polyphenols (powders, capsules, drinks);
• Functional plant-based ingredients used in the food industry or nutraceuticals.

Further analyses to consider

To enrich your study or complete a polyphenolic profile, you can combine the sinapic acid assay with other analyses available in our catalogue:

• Ferulic acid assay (HPLC, LC-MS) : another hydroxycinnamic acid with antioxidant effects;
• Dosage of total or specific flavonoids (rutin, quercetin, luteolin);
• Dosage of caffeic acid : often associated with sinapic acid in plant extracts;
• Evaluation of overall antioxidant activity (DPPH or ORAC method);

This analytical framework will allow you to better utilize your natural extracts, secure your formulations and guarantee their functional effectiveness.
