Abstract
A new flow injection chemiluminescence (CL) system was used for the determination of noscapine. This technique is based on the reduction effect of noscapine on the Ru(phen)33+, which is produced by reaction between Ru(phen)32+ and acidic Ce(IV) solutions, and this rapid reduction produces strong CL. Calibration plots were linear over the range of 3.0×10-7-2.0×10-6 mol L-1 and 2.0×10-6-2.0×10-4 mol L-1. The CL intensity was so high, that it is able to produce a detection limit of 6.6×10-8 M noscapine (3σ). The relative standard deviation of 2.0×10-6 M noscapine was 1.0% (n=10). The proposed method was successfully applied for the flow injection determination of noscapine in cough and Tonin syrup samples. The results of real sample analyses show good recovery percentages (97.3-102.4%). The minimum sampling rate was 100 samples per hour.
