Abstract:
Objective To establish a simple, feasible and precise quality control method for the determination of contents and related substances of demethyl levophencynonate hydrochloride (L-LPC)tablets.Methods The mobile phase consisted of methanol,acetonitrile and sodium acetate buffer solution(pH 5.0),at a ratio of 4∶3∶3,at a flow rate 1.0 ml/min and a detection wavelength of 220 nm.Samples were injected 100 μl and determined at room temperature.Results The calibration curves showed good linearity (R2 =1) within the test range of 0.1-50μg/ml.The recovery of the method was about (100.15 ±0.73)%, and the stability of working solutions was acceptable in 8 h (RSD=0.36%).Conclusion The results indicated that the developed method can be readily used as a quality control method.
