Caffeic acid dosage

Caffeic acid (3,4-dihydroxycinnamic acid) is a naturally occurring polyphenol belonging to the hydroxycinnamic acid family of phenolic acids, widely present in the plant kingdom. It is found in matrices as varied as coffee, thyme, rosemary, propolis, berries, and medicinal plants.

Known for its antioxidant, anti-inflammatory and antimicrobial properties, caffeic acid is commonly analyzed in the fields of phytotherapy, nutraceuticals, natural cosmetics, but also in the context of antioxidant power evaluations of raw materials of plant origin.

Why measure caffeic acid?

The determination of caffeic acid is essential in several industrial and scientific contexts:

• Standardization of plant extracts rich in polyphenols
• Evaluation of the overall antioxidant activity of food or cosmetic ingredients
• Quality control of botanical raw materials (extracts, powders, tinctures)
• Comparison between natural and synthetic origin
• Monitoring molecule stability in complex formulations

The analysis also makes it possible to support functional claims on antioxidant, anti-aging or anti-inflammatory formulations.

Analytical techniques used

YesWeLab offers reliable analyses adapted to each type of matrix using the following techniques:

• HPLC-DAD (liquid chromatography with diode array detection): a common method for the separation and quantification of phenolic acids in plant extracts.
• LC-MS (liquid chromatography coupled with mass spectrometry): ideal for complex matrices or low concentrations; allows precise identification even in the presence of interferents.
• UV-Vis spectroscopy: rapid and economical method in simple extracts or for screenings.

Our experts adapt the method according to your regulatory, technical or commercial objectives.

Commonly analyzed matrices

The dosage of caffeic acid is relevant in a wide range of products:

• Extracts of aromatic and medicinal plants (thyme, rosemary, sage, nettle, etc.)
• Green or roasted coffees, infusions, functional drinks
• Antioxidant herbal food supplements
• Natural cosmetics: creams, serums, anti-aging lotions
• Products containing propolis or other beekeeping substances

Areas of application

This analysis is of particular interest to players in the following sectors:

• Nutraceutical industry: valorization of polyphenolic extracts in health supplements
• Functional food and health drinks
• Natural and organic cosmetics: control of anti-aging and antioxidant active ingredients
• Botanical research and pharmacognosy
• Processing of medicinal plants: batch control and standardization
