| 英文摘要 | hawthorn is a traditional chinese medicine and fruit. it contains numerous organic acids. it is reported that organic acids have the ability to cure indigestion and have many other functions. a quantitative reversed-phase high performance liquid chromatography method using diode array detector has been developed for the determination of citric acid and malic acid in hawthorn. a hypersil ods2 column was used with phosphate buffer solution ( ph = 2. 6) as the mobile phase at a flow rate of 0.8 ml/min. the column temperature was 25 degrees c and the uv detection wavelength was 210 nm. the calibration curve for citric acid and malic acid was in good linearity in the range of 0.50 - 50.04 mu g with the regression equation y = 78. 2x - 0.08, r = 0.9999 and 0.10 - 10.00 mu g, y = 65.1x - 0.065, r = 0.9999, respectively. the average recoveries of three concentration leveds for citric acid and malic acid in hawthorn were 95.5% - 96.6% and 100.2% 103.7%, respectively. rsd were 0.11% - 0.38% and 0.41% - 53%, respectively. the detection limits for citric acid and malic acid were 0.04 mu g and 0.03 mu g (s/n 3), respectively. the results indicate that this method is fast, sensitive, reproducible and practical for the routine analysis of organic acids in hawthorn. |
