Abstract:

The study aimed to develop an high performance liquid chromatography (HPLC) method for the determination of neochlorogenic acid, chlorogenic acid, caffeic acid, luteolin-7-O-glucoside, 3,5-dicaffeoylquinic acid, 4,5-dicaffeoylquinic acid, luteolin, apigenin, loganin, sweroside, secoxyloganin; (R, S)-goitrin and clemastanin B in Koujie gargle. Separation was carried out using Waters Symmetry C18 (250 mm×4.6 mm, 5 μm) with mobile phase of acetonitrile-0.3% phosphoric acid in gradient elution. The detection wavelength was set at 348 nm, 240 nm and 224 nm. The flow rate was 1.0 mL/min, and the column temperature was 30 ℃. The results show that the linear relationship of 13 chemical components in Koujie gargle is good (r≥0.999 1), the average recovery ranges from 96.92% to 100.11%, and the RSD ranges from 0.53% to 1.58%. The established HPLC wavelength switching method is accurate which can be used for the quality control of Koujie gargle.

Key words: Koujie gargle, high performance liquid chromatography, oral care products, content determination
