[Identification of 4-hydroxycoumarin derivatives by means of derivative spectroscopy (author's transl)].

摘要: Presented here is a rapid method of identifying 4-hydroxycoumarins in organs or blood samples. Using an ultrasonic homogenizer, complete analysis obtained less than 30 min. Coumarin derivatives are identified by means derivative UV spectroscopy the normal spectrum and its first derivation at 340 to 240 nm. HPTLC can be employed as supplementary identification method.
