摘要
目的:探讨不同烟熏条件加工的当归药材中15种无机元素的含量及分布特征,确定最佳烟熏加工工艺。方法:采用ICP-MS测定31个烟熏当归样品中8种重金属元素含量,AAS测定其他7种无机元素含量,利用IBM SPSS 21.0及SIMCA-P 11.5软件进行统计分析。结果:不同烟熏条件加工的当归药材中无机元素特征性指纹表现为K>Na>Cr>Cu的趋势;烟熏温度是影响烟熏当归药材中无机元素分布的最关键因素;最佳烟熏加工工艺为50℃烟熏8 h。结论:调控温度和时间进行烟熏加工的当归药材安全性良好。
Objective： To investigate contents and distribution characteristics of 15 kinds of inorganic elements in Angelicae Sinensis Radix smoked by different processing conditions, and to determine optimum smoked processing technology. Method： Contents of 8 heavy metal elements in 31 smoked samples were determined by ICP-MS, and the other 7 inorganic elements were determined by AAS, IBM SPSS 21.0 and SIMCA-P 11.5 statistical software were used for statistical analysis. Result： Fingerprint characteristic of inorganic elements in Angelicae Sinensis Radix smoked by different processing conditions showed the same trend of K 〉 Na 〉 Cr 〉 Cu;. temperature was the key factor affecting distribution of inorganic elements in smoked Angelicae Sinensis Radix; optimal smoked processing conditions were smoked for 8 hours at 50 ℃. Conclusion： Smoked processing of Angelicae Sinensis Radix had good safety by regulation of temperature and time.
