Abstract:
Objective To establish the method for the simultaneous determination of liquiritin, ammonium glycyrrhizinate, hesperidin, nobiletin;tangeretin;costunolide, dehydrocostuslactone in Chenxiang Lubailu tablet by HPLC. Methods ZORBAX Eclipse XDB-C18 chromatographic column (4.6 mm×250 mm, 5 μm) was used. The mobile phase was methanol-0.1% phosphoric acid solution. Gradient elution with flow rate of 1.0 ml/min was used. Column temperature was 35 ℃. Detection wavelength for liquiritin, ammonium, tangeretin, and costunolide was at 237 nm. Detection wavelength for glycyrrhizinate was at 283 nm. Detection wavelength for hesperidin and nobiletin was at 330 nm. Injection volume was 10 μl. 16 batches of samples were tested. Results The linear ranges for the detection of liquiritin, ammonium, glycyrrhizinate, hesperidin, nobiletin, tangeretin, and costunolide were 1.110 - 55.72 (r=0.9992), 22.15 - 1108 (r=0.9999), 6.140 - 307.2 (r=0.9995), 1.130 - 56.25 (r=0.9997), 0.3700 - 18.75 (r=0.9982), 0.5200 - 26.01 (r=0.9991), and 1.180 - 58.95 (r=0.9999) μg/ml respectively. The average recoveries were 98.71%, 98.12%, 98.44%, 98.22%, 99.17%, 99.18%, and 97.93%, and the RSDs were 0.16%, 0.67%, 0.57%, 0.62%, 0.48%, 0.56%, and 0.58% respectively. The contents of the seven components in 16 batches of samples were 0.1250 - 1.174, 2.354 - 7.426, 1.822 - 27.21, 0.0370 - 1.399, 0.0723 - 0.4433, 0.0140 - 0.1990, and 0.2207 - 1.407 mg/g respectively. Conclusion The method is accurate, reproducible and durable, which could be used to the quality control and evaluation of Chenxiang Lubailu tablet.
