煎膏剂质量控制指标考察

Investigation of Indexes in Quality Control of Decocted Extract

摘要:

目的: 探讨煎膏剂(膏滋)的质量控制指标。 方法: 在传统浓缩、收膏经验指导下,测定清膏、膏滋成品的相对密度、含水量、动力黏度等参数,并对以上指标间进行相关性研究。 结果: 相对密度、含水量、动力黏度3项指标易测且稳定可靠,相对密度与含水量存在负相关性。 结论: 相对密度、含水量、动力黏度3项可作为膏滋浓缩、收膏工艺的质量控制指标,为膏滋剂质量标准的建立提供试验依据。

Abstract:

Objective:To explore indexes in quality control of decocted extract. Method: Under guidance of traditional concentrated and cream collection experience,to determine relative density,moisture content,kinetic viscosity and other parameters of semi-finished extract and decocted extract,and correlation study of the above indexes was carried out. Result: Three indexes(relative density,moisture content,kinetic viscosity) was stable,reliable and easily measured,relative density had a negative correlation with moisture content. Conclusion: Relative density, moisture content and kinetic viscosity could be selected as reasonable indexes in quality control of decocted extract,this study provided experimental basis for establishment of decocted extract quality standard.
