藏药打箭菊的质量标准研究

目的：建立藏药打箭菊的质量标准。方法：采用显微、薄层色谱法建立其鉴别方法；参考2010年版《中国药典》（一部）相关方法测定其水分、总灰分、酸不溶性灰分和浸出物的含量；采用高效液相色谱法测定木犀草素的含量。结果：藏药打箭菊药材的显微、薄层色谱鉴别特征明显，专属性强；打箭菊药材中木犀草素含量为0.036%~0.104%（均值0.078%），水分为9.32%~15.82%（均值13.11%），总灰分为6.65%~8.29%（均值7.45%），酸不溶性灰分为0.23%~0.59%（均值0.42%），浸出物为21.42%~30.15%（均值24.86%）。结论：本文建立的方法操作简单、准确可靠、重复性良好，可用于控制打箭菊药材的质量。

Quality Standard of Pyrethri Tatsienenis Flos

This study was aimed to establish the quality standard of Pyrethri Tatsienenis Flos. The medical material was identified by the microscopy and the thin layer chromatography (TLC) methods. The moisture, total ash,acid-insoluble ash and alcohol-soluble extract were determined according to procedures recorded in the Chinese Pharmacopoeia (2010 edition). The content of luteolin was determined by the HPLC method. The results showed a strong characteristic microscopic of Pyrethri Tatsienenis Flos, and its TLC identification had a good resolution with clear spots. The mass fractions of luteolin was 0.036%~0.104% (average of 0.078%), moisture was 9.32%~15.82% (average of 13.11%), total ash was 6.65%~8.29% (average of 7.45%), acid-insoluble ash was 0.23%~0.59% (average of 0.42%), and the extraction was 21.42%~30.15% (average of 24.86%).It was concluded that this established standard was simple to operate with good stability and reproducibility,which can be used for quality evaluation of Pyrethri Tatsienenis Flos.
