天芎头风片质量标准研究

目的建立天芎头风片的质量标准。方法采用显微鉴别法对方中全蝎进行鉴别;采用薄层色谱法对方中川芎、延胡索进行定性鉴别;采用高效液相色谱法对天芎头风片中天麻素进行含量测定。结果全蝎的显微鉴别方法专属性强,简单可行。川芎、延胡索的薄层色谱鉴别方法斑点清晰,重现性好。天麻素进样量在0.44-1.31μg范围内与峰面积呈良好线性关系,r=0.999 5;平均回收率为99.76%,RSD=1.17%（n=6）。结论所建立的方法稳定、准确、重复性好,可用于天芎头风片的质量控制。

Quality Standard of Tianxiong Toufeng Tablets

Objective To establish the quality standard for Tianxiong Toufeng Tablets. Methods Scorpio in this preparation was identified by the microscopic identification method; Ligusticum chuanxiong and Rhizoma corydalis were qualitatively identified by TLC; the gastrodin content was determined by HPLC. Results The microscopic identification method of scorpio was strongly specific,simple and feasible; the spots of TLC for identifying Ligusticum chuanxiong and Rhizoma corydalis were clear with good reproducibility. The sample size of gastrodin within the range of 0. 44- 1. 31 μg showed good linear relation with the peak area（r = 0. 999 5）. The average recovery rate of gastrodin was 99. 76%,RSD = 1. 17%（n = 6）. Conclusion The established methods are stable and accurate with good reproducibility,which can be used for the quality control of Tianxiong Toufeng Tablets.
