瑶族药七爪风药材质量标准

目的:制定瑶族药七爪风药材质量标准,为药用植物资源的开发利用提供科学依据。方法:分别对瑶族药七爪风药材的性状、显微特征进行观察,按照2010年版《中国药典》方法对10个不同产地药材中浸出物、灰分、水分进行测定,采用薄层色谱法对其定性研究以及HPLC色谱法对其进行含量测定。结果:对药材的性状、显微特征进行了描述;暂定七爪风药材总灰分不得过7%,酸不溶性灰分不得过4%,水分不得大于11%;TLC中蔷薇酸的斑点清晰、无拖尾,含量测定中蔷薇酸的稳定性、重复试验中RSD均﹤2%,瑶族药七爪风10个产地药材蔷薇酸的含量在0.093 1%~0.244 3%,因此暂拟定每克七爪风药材蔷薇酸不0.08%。结论:通过研究初步制定了瑶族药七爪风药材的质量控制标准。

Quality Standards of Radix of Rubus reflexus var. lanceolobus

Objective: To provide scientific basis for the utilization and development of radix of Rubus reflexus var. lanceolobus by setting up the quality standards of radix of R. reflexus var. lanceolobus. Method: The properties and microscopic characteristics of radix of R. reflexus var. lanceolobus were observed. Extract, moisture and ash of the herbs from 10 different origins were determined according to the methods in Chinese Pharmacopoeia;qualitative research was done with TLC and their contents were determined by HPLC method. Result: The properties and microscopic characteristics of radix of R. reflexus var. lanceolobus were described;total ash was not more than 7%, acid-insoluble ash was not more than 4%, and moisture was not more than 11%for radix of R. reflexus var. lanceolobus. The spots of euscaphic acid were clear with no trailing in TLC;RSD was<2% in the stability and repeatability tests of euscaphic acid in content determination, and the content of euscaphic acid from 10 origins was 0.093 1%-0.244 3%, so it was temporarily determined that the euscaphic acid was not less than 0.08% in per gram of radix of R. reflexus var. lanceolobus. Conclusion: The established method can be used for the quality control of radix of R. reflexus var. lanceolobus.
