A high performance liquid chromatography with fluorometric and ultraviolet detection described to quantify 5-methoxypsoralen (5-MOP) percutaneous absorption in humans after the application of an essential oil, as well as 5-MOP in bergamot oil and cosmetics by fluorometric and voltammetric measurement, respectively. A muBondapack C(18) analytical column (particle size 5 microm, 3.9 x 300 mm) eluted with acetonitrile-tetrahydrofuran-water (70:15:15, v/v/v) containing 0.07% trifluoroacetic acid. The quantification limits are 0.05 and 0.26 ng for 5-MOP and 5-geranoxypsoralen, respectively. For fluorometric measurement was found linear over the range 0.05-3.00 microg/ml for psoralens. Five volunteers blood samples were collected over a 2-day period were investigated before and after treatment with bergamot oil. Serum levels of 5-MOP were significantly increased from the 4 h after the application of bergamot essential oil. The hourly mean levels were significantly higher after the application of bergamot essential oil compared to baseline values.

D009822	Oils, Volatile	Oils which evaporate readily. The volatile oils occur in aromatic plants, to which they give odor and other characteristics. Most volatile oils consist of a mixture of two or more TERPENES or of a mixture of an eleoptene (the more volatile constituent of a volatile oil) with a stearopten (the more solid constituent). The synonym essential oils refers to the essence of a plant, as its perfume or scent, and not to its indispensability.
