Objective: To establish a quantitative method for the determination of licorice glycosides and glycyrrhizic acid in the compound radix platycodi cough tablets by high-performance liquid chromatography (HPLC) coupled with ultraviolet detection. Methods: An Agilent C18 column (4.6 mm ×150 mm, 5μm) was adopted. The mobile phase consisted of a mixture of acetonitrile - 0.05% phosphoric acid in gradient elution at a flow rate of 1.0 mL·min-1, the detection wavelength was set at 237 nm; The sampling volume was 10μL; The column temperature was 30℃. Results: The calibration curve showed a good linearity in the range of 10.65~42.60 mg·L-1 (r=1.0000) for licorice glycosides and 97.30~389.30 mg·L-1 (r=1.0000) for glycyrrhizic acid, respectively. The average recoveries (n=6) of licorice glycosides and glycyrrhizic acid were 98.80% (RSD=0.73%) and 99.84% (RSD=0.10%), respectively. Six batches of compound radix platycodi cough tablets were measured and the content per pill was respectively as follows: liquorice glycosides, 135.28μg, 123.16μg, 113.21μg, 136.08μg, 160.84μg and 156.32μg; glycyrrhizic acid, 441.36μg, 405.86μg, 364.69μg, 446.93μg, 518.22μg and 509.65μg. Conclusions: The developed method is simple and reproducible, which can be used for the quantitative determination of licorice glycosides and glycyrrhizic acid in the compound radix platycodi cough tablets.
