摘　　要：目的 通过测定不同加工比例、贮存年份和加工工艺艾绒的灰分和水分,以期为艾绒质量标准的把控提供数据支撑。方法 艾绒灰分和水分的测定均参照《中国药典》法,灰分参照通则2302包括总灰分和酸不溶灰分,水分参照通则0832第四法甲苯法。结果 机器制艾绒总灰分为(7.54±1.89)%,酸不溶灰分为(0.07±0.02)%;实验室制艾绒总灰分为(8.83±1.31)%,酸不溶灰分为(0.08±0.01)%。与机器制30%艾绒相比,实验室制33%艾绒的总灰分及酸不溶灰分差异均无统计学意义(P>0.05)。多元线性回归分析表明加工比例与总灰分具有相关性(P<0.05)。试验分别测定了18份艾绒样品的水分值,水分含量相对稳定,最高值和最低值分别为3.0%和8.0%。结论 艾绒总灰分、酸不溶灰分及水分检测方法稳定可行;加工比例越高,艾绒灰分值越小。Objective To provide data support for the control of Moxa floss quality standards by determining the ash and moisture content of Moxa floss with different processing ratios, storage years, and processing techniques.Methods The determination of ash content and moisture in Moxa floss was conducted in accordance with the methods described in the Chinese Pharmacopoeia. The ash content was determined following General Rule 2302,which includes total ash and acid-insoluble ash, while the moisture content was assessed using the toluene method outlined in General Rule 0832. Results The total ash content of machine-made Moxa floss was(7.54±1.89)%,and the acid-insoluble ash content was(0.07±0.02)%. The total ash content of laboratory-made Moxa floss was(8.83±1.31)%, and the acid-insoluble ash content was(0.08±0.01)%. Compared to the machine-made 30% Moxa floss, there was no statistically significant difference in total ash and acid-insoluble ash content between the laboratory-made 33% Moxa floss(P>0.05). Multivariate linear regression analysis indicated a correlation between the processing ratio and total ash content(P<0.05). The moisture content of 18 Moxa floss samples was determined,showing a relatively stable moisture content, with the highest and lowest values being 3.0% and 8.0%, respectively.Conclusion The methods for determining the total ash, acid-insoluble ash, and moisture content in Moxa floss are stable and feasible;higher processing ratios result in lower ash content values in Moxa floss.
