采用超声波辅助萃取法提取,高效液相色谱法测定了锁阳(Cynomorium songaricum)中的熊果酸含量。在单因素试验基础上,以乙醇体积分数、料液比、超声时间、超声功率为研究对象,进行了4因素3水平正交试验。结果表明,熊果酸在4.0~16.0μg/μL范围内呈良好线性关系,回归方程为y=622.7x-85.517,r=0.9998,加样回收率为98.08%。锁阳中熊果酸最佳提取工艺为:超声功率150 W,料液比1:25,85%(V/V ,下同)乙醇超声提取30 min,在此条件下,锁阳中熊果酸含量为1.53%。该工艺能有效提取锁阳中熊果酸,为评价中药材中的熊果酸水平提供参考。
採用超聲波輔助萃取法提取,高效液相色譜法測定瞭鎖暘(Cynomorium songaricum)中的熊果痠含量。在單因素試驗基礎上,以乙醇體積分數、料液比、超聲時間、超聲功率為研究對象,進行瞭4因素3水平正交試驗。結果錶明,熊果痠在4.0~16.0μg/μL範圍內呈良好線性關繫,迴歸方程為y=622.7x-85.517,r=0.9998,加樣迴收率為98.08%。鎖暘中熊果痠最佳提取工藝為:超聲功率150 W,料液比1:25,85%(V/V ,下同)乙醇超聲提取30 min,在此條件下,鎖暘中熊果痠含量為1.53%。該工藝能有效提取鎖暘中熊果痠,為評價中藥材中的熊果痠水平提供參攷。

Ursolic acid in Cynomorium songaricum was ultrasonically extracted and detected by HPLC. According to singlefactor experiments,three levels of four factors including ethanol concentration,material -liquid ratio,ultrasonic time, and ultrasonic power were selected for the orthogonal design.The results showed that the calibration curve of ursolic acid was linear (r=0.999 8) in the range of 4.0~16.0 μg/μL.The equation was y=622.7x-85.517,r=0.999 8,and recovery was 98.08%. The optimum extraction was carried out in 85%(V / V) ethanol for 30 min with the ultrasonic power of 150 W,and the material-liquid ratio 1:25.Under the optimal conditions,the content of ursolic acid was 1.53%.The method can extract ursolic acid efficiently,and provide a reference for evaluation ursolic acid in medicinal materials.
