title: [Determination of tetracyclines by a new spectrum technique].
abstract: Tetracyclines are light-fluorescence substances, which cannot be detected directly by fluorometry. Herein a new spectrum method was proposed to detect tetracyclines directly by fluorometry. Under optimal conditions, the calibration graph is linear over the range 0.10-9.00 microg x mL(-1) for tetracyclines, and the detection limits of tetracycline, oxytetracycline, chlortetracycline and doxycycline are 0.065, 0.067, 0.068 and 0.070 microg x mL(-2), respectively.
