摘要	A high performance capillary electrophoresis method with diode array detector detection for the determination of five bioactive ingredients in Tibetan medicine Elsholtzia, namely quercetin, rutin, saussurenoside, kaempferol, and oleanolic acid, has been developed. The effects of several factors, such as the acidity, concentration of running buffer, separation voltage, temperature, and SDS concentration were investigated. The optimal conditions were 44 mmol/L boric acid running buffer (pH 8.5), 45 mmol/L SDS, 16 KV voltage, 20 degrees C, and 10.0% (V/V) of acetonitrile. Under the optimum conditions, five components could be separated with a good baseline resolution within 17 min. The calibration curves showed good linear relationship over the concentration range of 5 x 10(-4)similar to 0.1 mg/mL for quercetin, rutin, saussurenoside, kaempferol, and 1 x 10(-3) similar to 0.1 mg/mL for oleanolic acid. The average recoveries of the method and RSD were ( 99.2%, 3.2%) for quercetin, (102.1%, 2.1%) for rutin, (99.4%, 1.5%) for saussurenoside, (98.9%, 1.8%) for kaempferol, and (99.0%, 2.9%) for oleanolic acid, respectively. The detection limits (S/N = 3) were 1.1 x 10(-4) mg/mL for quercetin, 2.6 x 10(-4) mg/mL for rutin, 1.8 x 10(-4) mg/mL for saussurenoside, 2.9 x 10(-4) mg/mL for kaempferol, and 6.3 x 10(-4) mg/mL for oleanolic acid, respectively. The method was simple, rapid, and reproducible and could be applied for the determination of quercetin, rutin, saussurenoside, kaempferol, and oleanolic acid in Tibetan medicine Elsholtzia, and the assay results were satisfactory.; A high performance capillary electrophoresis method with diode array detector detection for the determination of five bioactive ingredients in Tibetan medicine Elsholtzia, namely quercetin, rutin, saussurenoside, kaempferol, and oleanolic acid, has been developed.
