目的:优化水溶性壳聚糖对黄莪凝胶水提液除杂的工艺条件.方法:以透光率比、杂质去除率、柚皮苷保留率的综合评分为指标,采用Box-Behnken响应面法优化除杂工艺中水溶性壳聚糖用量、振荡时间和温度,并进行验证.结果:比重≥1.3的中药水提液与0.01 g/mL水溶性壳聚糖溶液用量的体积比为2.2,70℃下振荡100 min除杂效果最佳;验证试验中3批样品的平均透光率比为87.3%、杂质去除率为41.50%、柚皮苷保留率为131.38%,综合评分的实测值分别为97.35%、98.92%、98.04%,与预测值(98.27%)的相对误差分别为-0.87%、0.73%、-0.16%.结论:该方法可有效优化水溶性壳聚糖对黄莪凝胶水提液的除杂工艺参数.%OBJECTIVE:To optimize the technology conditions of water-soluble chitosan on Huang'e gel water extract solu-tion. METHODS:Using the comprehensive scores of transmittance ratio,impurity removal rate,naringin retention rate as indexes, Box-Behnken response surface method was used to optimize the amount of water-soluble chitosan,shocking time and temperature in clarifying technology,and verification test was conducted. RESULTS:The clarification effect was the best when the volume ra-tio of TCM extract solution with proportion ≥1.3 to amount of 0.01 g/mL water-soluble chitosan was 2.2,shocking for 100 min at 70 ℃. In the verification test,the average transmittance ratio was 87.3%,impurity removal rate was 41.5%,and naringin reten-tion rate was 131.38%. The measured values of comprehensive scores were 97.35%,98.92% and 98.04%,showing relative error of -0.87%,0.73% and -0.16% with the predicted values(98.27%),respectively. CONCLUSIONS:The method can effectively optimize the clarification technology parameters of water-soluble chitosan on Huang'e gel water extract solution.
