A simple,rapid and sensitive chemiluminescence method for the determination of minocycline hydrochloride was developed based on the principle that the chemiluminescence intensity of luminol-potassium ferricyanide reaction system could be inhibited by minocycline hydrochloride in alkaline condition. Under the optimum condition,the linear range for minocycline hydrochloride was 8. 0 ~ 400 ng / m L,and the detection limit was 7. 4 ng / m L. The relative standard deviation( RSD) was 1. 8% for the eleven-time co...
