Citroptene (coumarin) dosage

Citroptene analysis allows for the quantification of this coumarin, naturally present in citrus fruits, within plant extracts, essential oils, beverages, or cosmetics. Also known as limettine, citroptene belongs to the coumarin family, and its analysis is essential for assessing the risks of photosensitization and precisely characterizing an extract. At YesWeLab, this citroptene analysis is performed by HPLC-UV through partner laboratories selected according to your matrix and requirements.

Why measure citroptene levels?

Citrus coumarins, including citroptene, are of particular interest in cosmetics and nutraceuticals. Some of these coumarins are associated with photosensitizing : when applied to the skin and then exposed to sunlight, they can cause skin reactions. Citroptene measurement thus serves several purposes: assessing the safety of an essential oil or topical product, verifying the compliance of an extract with industry recommendations, and precisely characterizing the composition of a plant-based raw material. This quantification is also a valuable tool for the authentication and quality control of citrus extracts. For manufacturers of essential oils, perfumes, and food supplements, it allows them to document the actual composition of a batch, detect potential adulteration, and provide customers and regulatory authorities with reliable and traceable analytical data.

Analytical technique: HPLC-UV

Citroptene quantification relies on HPLC (high-performance liquid chromatography) coupled with UV detection . This method offers excellent selectivity for separating citroptene from other coumarins and furocoumarins present in a complex matrix, as well as sensitivity suitable for low concentrations. The protocol is adjusted according to the nature of the sample—essential oil, extract, beverage, or cosmetic—and the desired limit of quantification. Our scientific team will guide you toward the most appropriate analytical conditions for your objectives.

Sectors and matrices concerned

Citroptene analysis is of primary interest to the nutraceutical and plant, with physicochemical expertise applied to plant extracts, essential oils, beverages, and cosmetic formulations. It is part of a comprehensive approach to coumarin control and ensuring the safety of natural products.

Accredited laboratories and expert support

At YesWeLab, we collaborate with a carefully selected network of laboratories, most of which are certified and/or accredited (ISO 17025, COFRAC, etc.). These laboratories are chosen based on your specific needs, the matrices to be analyzed, and the required analytical techniques or methods. If you have any particular requirements, please specify them in your request: our scientific team will do everything possible to respond accurately and promptly.

Since 2020, many manufacturers, distributors and design offices have trusted us to manage their analyses, entrusting us with their samples via our digital platform.

Additional analyses

For a complete characterization of the coumarins and furocoumarins in your extracts, citroptene measurement is combined with other analyses offered by YesWeLab:

• Dosage of bergamottin (furanocoumarin) — a furocoumarin characteristic of citrus fruits.
• Scopoletin (coumarin) assay — to broaden the coumarin profile.
• Umbelliferone (coumarin) dosage — a reference coumarin in many plants.
