摘 要:目的 用高效毛细管电泳法对红花中的有效成分腺苷、槲皮素和芦丁同时进行含量测定。方法 采用熔融石英毛细管柱 (66 5cm× 5 0 μmID ,有效长度 5 8cm)作为分离通道 ;以 5 0mmol·L- 1 硼砂其中含 18%甲醇的溶液 (pH9 7)为运行缓冲液 ;运行电压 :2 4kV ;毛细管柱温 :2 0℃ ;检测波长 :2 10nm。结果 以利福平为内标 ,腺苷、芦丁和槲皮素分别在 10~ 160mg·L- 1 ,10 0~ 2 0 0 0mg·L- 1 和 10 0~ 160 0mg·L- 1 线性关系良好 (r>0 998) ;平均回收率分别为98 5 %~ 10 0 5 % ,96 9%~ 99 5 %和 99 1%~ 99 5 % ;RSD分别为 6 5 % ,5 2 %和 5 6% (n =5 )。结论 此法操作简便快速 ,回收率及重现性好 ,可作为红花质量控制的方法。Aim To develop a method for determination of adenosine, rutin and quercetin in Carthamus tinctorius L. by high performance capillary electrophoresis(HPCE). Methods A fused silica capillary (66 5 cm×50 μm ID, an effective length of 58 cm) was used. The running buffer composed of 50 mmol·L -1 borax (pH 9 7) containing 18% methanol. The applied voltage was 24 kV and the capillary temperature was 20 ℃ . The detection wavelength was 210 nm. Rifampicin was used as internal standard. Results A good linearity between peak area ratio of the common peak to the internal standard and the concentration was found in the range of 10-160 mg·L -1 for adenosine, 100- 2 000 mg·L -1 for rutin and 100- 1 600 mg·L -1 for quercetin ( r >0 998). The average recoveries were 98 5%-100 5%, 96 9%-99 5% and 99 1%-99 5% for adenosine, rutin and quercetin, respectively. The relative standard deviation was less than 6 5%( n =5). Conclusion The method is simple, rapid and with satisfactory recoveries and good reproducibilities. It can be used to control the quality of Carthamus tinctorius .
