不同产地五倍子的质量评价

目的对不同产地的五倍子质量开展评价,以期为五倍子的质量控制提供依据。方法对不同产地的五倍子进行水分、总灰分、没食子酸含量测定,建立特征图谱,对五倍子开展多个角度的质量评价。结果安徽、内蒙古、陕西、湖北及四川等地的五倍子水分、总灰分含量情况均符合中国药典标准,且没食子酸含量高于标准;特征图谱结果表明12批五倍子受产地的影响较大,其中安徽和湖南产地的五倍子样品与贵州、内蒙古产地的五倍子样品相比差异较大。综合质量多方位评价结果,内蒙古产五倍子为推荐品。结论五倍子质量系统评价可更完整地体现不同产地的质量情况,为完善五倍子质量控制方法提供一定科学基础。

Quality Evaluation of Wubeizi(Galla Chinensis)from Different Origins

Objective To evaluate the quality of Wubeizi(Galla Chinensis)from different areas in order to provide the basis for the quality control of Wubeizi(Galla Chinensis).Methods The moisture,total ash,and gallic acid content of Wubeizi(Galla Chinensis)from different origins were determinated,the characteristic maps were established,and the quality evaluation of Wubeizi(Galla Chinensis)from multiple angles was carried out.Results The moisture,and total ash content of Wubeizi(Galla Chinensis)in Anhui,Inner Mongolia,Shanxi,Hubei and Sichuan all met the Chinese pharmacopoeia standards,and the gallic acid content was higher than the standard;the characteristic map results showed that 12 batches of Wubeizi(Galla Chinensis)were greatly affected by the place of production,among them,the Wubeizi(Galla Chinensis)samples from Anhui and Hunan provinces were quite different from those from Guizhou and Inner Mongolia.Based on the results of multi-directional quality evaluation,Wubeizi(Galla Chinensis)produced in Inner Mongolia is recommended.Conclusion The quality system evaluation of Wubeizi(Galla Chinensis)can more completely reflect the quality of different producing areas,and provide a scientific basis for improving the quality control methods of Wubeizi(Galla Chinensis).
