 Um·bel·lif·er·one n. Chem. A tasteless white crystalline substance, C9H6O3, found in the bark of a certain plant (Daphne Mezereum), and also obtained by the distillation of certain gums from the Umbelliferae, as galbanum, asafetida, etc.  It is analogous to coumarin.  Called also hydroxy-coumarin.  Its strong fluorescence under ultraviolet light makes it useful in analytical biochemistry, as, for example, to detect phosphatase activity by hydrolysis of umbelliferyl phosphate.
