Umbelliferone may be used as an analytical reference standard for the determination of the analyte in Aegle marmelos fruit using reversed-phase high performance liquid chromatography. It is also used as a template for the synthesis of molecularly imprinted polymers used in the analysis of plant samples.
General description
Umbelliferone is a naturally occurring coumarin, present in a variety of medicinal plants from the Apiaceae (Umbelliferae) family and also in plants from other families such as mouse-ear hawkweed.
