英文摘要 | A micellar electrokinetic capillary chromatographic method was established for the determination of2-(3-hydroxy-4-methoxyphenyl)ethyl 1-O-[ α -L-arabi- nopyranosyl(1 → 6)]-feruloyl(1 → 4)- α -L-rhamnopyranosyl(1 → 3)- β -D-glucopyra noside (SN-A), harpagoside (SN-B) and cinnamic acid (SN-C) in the traditional Chinese medicinal prescription, Bai-He-Gu-Jin-Tang, which contains Scrophulariae Radix. This chromatographic technique was carried out using a buffer composed of 20 mM sodium tetraborate and sodium dihydrogen phosphate containing 120 mM sodium cholate and 12 % methanoi at pH 7.5. 2-(4-Hy- droxyphenyD-ethylammonium chloride was used as an internal standard and detected at 280 nm. The linear calibration ranges for SN-A, B and C were 11.76- 188.16 ug/mL (r = 0.9998), 8.16-130.56 Ug/mL (r = 0.9992) and 4.48-71.68 ug/mL (r=0.9991), respectively. The recoveries of the markers listed above were SN-A: 104.3 ± 2.8 %, SN-B: 98.1 ± 2.2 % and SN-C: 98.2 ± 1.4 %. The relative standard deviations of the three marker substances for intraday and interday analyses ranged from 0.85 to 2.87 % and from 1.42 to 4.14%, respectively. |
