Quantitation (μg/mg of extract) of malassezin, indirubin, indolo[3,2-b]carbazole (ICZ), tryptanthrin and 6-formylindolo[3,2-b]carbazole (FICZ) by HPLC/UV in the extracts of clinical M. furfur strains originating from seborrheic dermatitis, pityriasis versicolor, folliculitis and healthy subjects. Values are means and standard deviations of three independent measurements.
