| 摘 要： | 建立了以Triton X-114为表面活性剂的浊点萃取-分光光度法同时测定厚朴酚与和厚朴酚含量的新方法,探讨了溶液的pH,Triton X-114浓度、平衡温度和平衡时间等因素对浊点萃取的影响.在最佳条件下,厚朴酚与和厚朴酚含量的线性方程分别为Y1=5.89×10-4x-1.14×10-3(相关系数为0.992 1),Y2=5.52×10-4x+7.71×10-5(相关系数为0.999 2);检测限分别为2.5μg/L和1.0μg/L.该方法成功用于药材中厚朴酚与和厚朴酚含量的测定,回收率为98.4%~104.3%.

| Abstract: | A new method of cloud point extraction-UV spectrophotometry based on using Triton X-114 as an extractant was developed for simultaneous determination of magnolol and honokiol in traditional Chinese medic -inal material.The effects of the pH of solution , concentrations of surfactant Triton X-114, equilibrium temper-ature and time on the efficiency of cloud point extraction were systematically examined .Under the optimized conditions, the linear equations were Y1 =5.89 ×10^-4x-1.14×10^-3（R2 =0.992 1）, Y2 =5.52×10^-4x-1.14×10^-5（R2 =0.999 2）, the detection limits were 2.5 μg/L, 1.0 μg/L for magnolol and honokiol, re-spectively .This method was applied to the determination of honokiol and magnolol in traditional Chinese me -dicinal material with recoveries of 98.4%~104.3%. |
