| 摘 要： | 目的 应用响应面法及超声波辅助优化马比木Nothapodytes pittosporoides中喜树碱的提取工艺。 方法 采用高效液相色谱法测定喜树碱含量，以市售马比木为研究对象，在单因素实验的基础上，选取甲醇体积分数、液料比及超声时间为影响因素，喜树碱提取率为响应值，通过Box-Behnken响应面法设计3因素3水平实验，确定最优提取工艺。 结果 最优提取工艺为甲醇体积分数46.4%，超声时间26.1 min，液料比21.20 mL·g?1，喜树碱的提取率为0.084 4%，二项式拟合相关系数R2为0.969 3，预测值与实验值偏差为3.2%。 结论 采用Box-Behnken优化马比木中喜树碱提取工艺，精确度高，预测值与实验值吻合度较高，预测性良好。图2表3参13

| Abstract: | Objective This study aims to optimize extraction process of camptothecin from Nothapodytes pittosporoides by response surface method and ultrasonic wave. Method The content of camptothecin was determined by high performance liquid chromatography, and N. pittosporoides wood available on the market was used as the research object. Based on the single factor experiment, methanol concentration, liquid to solid ratio and ultrasonic time were taken as the influencing factors, and the extraction rate of camptothecin as the response value. Box-Behnken response surface method was used to design the experiment with 3 factors and 3 levels, so as to determine the optimal extraction process. Result The optimal extraction process was as follows: methanol concentration 46.4%, ultrasonic time 26.1 min, liquid to solid ratio 21.20 mL·g?1, extraction rate of camptothecin 0.084 4%, binomial fitting correlation coefficient R2 0.969 3, and deviation between the predicted value and the experimental value 3.2%. Conclusion Box-Behnken can be used to optimize the extraction process of camptothecin from N. pittosporoides, with high precision and good predictability. Ch, 2 fig. 3 tab. 13 ref.] |
