摘要
目的:建立中药材总灰分定值分析方法及不确定度评定方法。方法:选择穿山龙、栀子、夏枯草3种中药材作为研究对象,以其总灰分为特性量,根据《中国药典》对3种中药材总灰分定值分析方法进行研究,并按照标准物质技术规范及相关计量技术规范要求,对测定过程中不确定度的引入进行系统分析。结果:当取置信概率P=95%时,穿山龙、栀子、夏枯草中药材总灰分测定标准值及其不确定度分别为(1.72±0.15)%、(4.82±0.21)%、(9.39±0.39)%。结论:本文建立的中药材总灰分定值分析及不确定度评定分析结果可靠,为中药材有证标准物质研制提供了基础研究结果。
OBJECTIVE：To establish value determination method of total ash from Chinese herbal medicine and uncertainty evaluation.METHODS：According to Chinese Pharmacopoeia and Technical Norm of Primary Reference Material and Technical Norm of Measurement,we conducted study on value determination method of total ash from 3 kinds of Chinese herbal medicine and systematically evaluated the uncertainty in the determination.RESULTS：When P was equal to 95%,the standard values of total ash and uncertainty of Dioscorea nipponica,Gardeniae jasminoides,Prunella vulgaris were 1.72%±0.15%,4.82%±0.21%and 9.39%±0.39% respectively.CONCLUSION：Established value determination method of total ash and results of uncertainty evaluation are reliable and used as basic study of certified reference material.
