ABSTRACT
Objective:
A method for simultaneous determination of 10 active ingredients in Dahuang Lidan Tablets (DLP) by HPLC wavelength switching method was established, and its quality was evaluated by statistical analysis.Methods:
A Phenomenex Kinetex C18 column was used with a column temperature of 30 ℃ and a mobile phase gradient of methanol-0.15% phosphoric acid. The flow rate was 1 mL/min and the detection wavelengths were 265.0 nm (0-5.8 min, gallic acid), 283.9 nm (5.8-7 min, 5-hydroxymethyl furfural), 222.2 nm (7-18 min, corilagin, p-hydroxybenzaldehyde), 256.7 nm (18-74 min, ellagic acid, aloe-emodin, rhein, emodin, chrysophanol, emodin methyl ether), respectively. Statistical analysis of the content of components in 10 batches of drugs was performed using SPSS 21 Software.Results:
The linearity of 10 components in the respective mass concentration ranges was good (r > 0.998 0), the average sample recovery was in the range of 98.45%-100.12%, and the RSD was in the range of 0.80%-2.51%. The content of 10 components was as follow gallic acid (8.371-11.438 mg/tablet), 5-hydroxymethylfurfural (0.046-0.087 mg/tablet), corilagin (0.721-2.094 mg/tablet), p-hydroxybenzaldehyde (0.034-0.065 mg/tablet), ellagic acid (1.736-1.996 mg/tablet), aloe-emodin (0.337-0.440 mg/tablet), rhein (1.636-2.562 mg/tablet), emodin (0.602-0.846 mg/tablet), chrysophanol (0.388-0.566 mg/tablet) and emodin methyl ether (0.621-0.781 mg/tablet). The quality of the 10 batches of samples was basically the same.Conclusion:
This method is simple and accurate and can be used for the quality control of DLP.
