[Determination of uric acid by chemiluminescence].

A novel chemiluminescence method for the determination of uric acid based on its inhibitory effect on the catalysis of Co2+ for the oxidation of luminol by H2O2 is described. The proposed method is simple, very sensitive and inexpensive. The decrease of cheniluminescence intensity is linearly correlated with uric acid concentration.

[Determination of 2,3,5,4'-tetrahydroxystilbene-2-O-beta-D-glucoside in the traditional Chinese preparation by high performance liquid chromatography with chemiluminescence detection].

Based on the chemiluminescence reaction of KMnO4-HNO3-2,3,5,4'-tetrahydroxystilbene-2-O-beta-D-glucoside sensitized by HCHO, an analytical method for 2,3,5,4'-tetrahydroxystilbene-2-O-beta-D-glucoside by RP-HPLC with chemiluminescence detector was developed. The chromatographic conditions were optimized. AN ODS hypersil column(25 mm x 4.

[Determination of Levofloxacin by chemiluminescence method].

A novel chemiluminescence method for the determination of Levofloxacin is based on its enhancement effect on thereaction of luminol with H2O2. The calibration graph is linear over the range of 5.53 x 10(-11)-2.
