不同加工方法对白芷质量的影响

Effects of Various Processings on Quality of Angelica dahurica

目的考察不同加工方法对白芷质量的影响。方法选取不同地点白芷样品,分别以水洗和刷除方式进行表面除沙,均分后分别切片和切块处理,干燥粉碎,测定各样品的总灰分、浸出物、欧前胡素含量和高效液相色谱指纹图谱相似度。结果总灰分以"水洗"和"水洗+切片"处理最低,浸出物以"切块"和"水洗+切块"处理最高,欧前胡素含量以"未水洗"和"未水洗+切片"最高。结论白芷产地加工不宜水洗和切制。

Objective To study the quality difference of various processing methods about Angelica dahurica.Methods Samples were selected from different places,clean silt by washing and brushing,cut slices and cut blocks in equal division,dried and comminution,to determine total ash,ethanol thermal extract,imperatorin content and HPLC fingerprint similarity.Results The content of total ash was the lowest in ＂washed＂ and ＂washed cut slice＂ sample,dilute ethanol thermal extract was the highest in ＂cut blocks＂ and ＂washed cut blocks＂ sample,imperatorin content was the highest in ＂non-washed＂ and ＂non-washed cut slice＂ sample.Conclusion Washed and cut process is not suitable in place of origin about Angelica dahurica.
