正交试验优选傣药喉舒宝的提取工艺

To Optimum Extraction Process for Preparation of Dai Medicine Houshubao through Orthogonal Test

目的:优选傣药喉舒宝的提取工艺。方法:以水为溶媒,干膏收率以及黄芩苷含量为综合考察指标,采用L9(3)4正交试验法对傣药喉舒宝提取工艺进行优选。结果:提取次数和加水量对考察指标具有显著性影响。优选的傣药喉舒宝的水提最佳工艺为加水10倍,提取3次,每次1.0h。结论:优选得到的傣药喉舒宝水提工艺,经中试放大,稳定可行。

Objective： To find out the optimum extraction process for the preparation of Dai medicine Houshubao. Method： L9 （3）^4 orthogonal testmethod was used to optimize the water extraction techniques, with the yield of extract and the content of baicalin as the indexes. Result： The amount of water and extraction times showed significant influence on the indexes. The optimal process was as follows： adding 12 folds of water, extracting 3 times for 1.0 hours each extraction. Conclusion： The optimized extraction process is stable and feasible for the production of Dai medicine Houshubao.
