Description générale

Esculetin is a derivative of coumarin, found in various plant species including Cichorium intybus (chicory), Bougainvillea spectabilis, Artemisia capillaris, etc and leaves of Citrus limonia (Rutaceae), Ceratostigma willmottianum, etc. It exhibits multiple pharmacological activities and is found to be a potent inhibitor of cyclooxygenase, 5-lipoxygenase, 12-lipoxygenase, catechol-O-methyl transferase, NADPH oxidase and xanthine oxidase enzymes.[1][2]

Application

Esculetin may be used as an analytical reference standard for the determination of the analyte in biological[3][4] and water samples[5] by chromatography-based techniques. It may also be used as a standard in the quantification of the analyte in traditional herbal medicines[6][7] by solid-phase extraction and micellar electrokinetic capillary methods, respectively.
