| 摘要： | 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。 |
| ABSTRACT： | OBJECTIVE： To optimize the technology conditions of water-soluble chitosan on Huang’e gel water extract solution. 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 ratio 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 retention 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. |
