The Metabolism of Umbelliferone and Herniarin in Rats and by the Rat Intestinal Microflora
Xenobiotica, 19711. The metabolism of umbelliferone (7-hydroxycoumarin) and herniarin (7-methoxycoumarin) was studied in rats after oral and intraperitoneal administration.2. Umbelliferone was excreted in the urine partly unchanged but mainly as a glucuronide and/or sulphate conjugate.

Magnetic activated release of umbelliferone from lipid matrices
International Journal of Pharmaceutics, 2010Lipid matrices containing dispersed superparamagnetic iron oxide (SPIO) particles were investigated as a magnetic field-responsive drug delivery system. Lipid matrices were prepared by combining myristyl alcohol, fatty acid coated SPIO particles, and umbelliferone (UMB).

Fluorescence of some simple umbelliferone derivatives
Collection of Czechoslovak Chemical Communications, 1979The absorption and fluorescence spectra of umbelliferone were studied; it was found that in the excited state the basicity of the α-pyrone part of the molecule increases to such an extent that it exceeds that of the phenolate oxygen of the molecule. This is responsible for the neutral nondissociated form of umbelliferone being only in nonpolar medium ...
