Dosage of sinapic or sinapinic acid

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

From a functional perspective, sinapic acid is recognized for its powerful 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, as well as anti-aging or protective cosmetic treatments.

Why measure sinapic acid?

Sinapic acid measurement is a valuable tool in several industrial and research contexts. It allows in particular to:

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

Accurate quantification of sinapic acid also helps support functional claims or guide the selection of botanical extracts based on their polyphenolic profile.

Available analytical methods

At YesWeLab, the analysis of sinapic acid is based 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 within ISO 17025 certified and/or COFRAC accredited partner laboratories, guaranteeing complete traceability of the results.

Analyzed matrices

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

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

Additional analyses to consider

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

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

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