瑶药材犁头草质量标准研究

Study on quality standard of Violae inconspicuae herba

目的建立瑶药材犁头草的质量标准。方法从性状、显微、薄层色谱(TLC)方面对12个批次犁头草进行定性鉴别,按照药典方法测定药材水分、总灰分及酸不溶性灰分、浸出物。结果各鉴别方法专属性强,12批犁头草药材色谱与对照品色谱在相同位置,显相同颜色的荧光斑点;药材水分为8.72%~11.61%,总灰分为10.03%~18.31%,酸不溶性灰分为1.17%~5.91%,纯水浸出物含量为29.06%~37.16%。结论该研究建立的质量标准可用于瑶药材犁头草的质量评价。

Objective To establish the quality standard of Yao medicine Violae inconspicuae herba.Methods Twelve batches of Vi⁃ola inconspicua Blume were identified in respects of properties,microscopic characteristics and TLC.According to the Pharmacopoeia method,moisture,total ash,acid insoluble ash and extractives were determined.Results Identification methods were highly specific.The chromatogram of 12 batches of Viola inconspicua Blume.presented the fluorescence spots of the same colors as the control at the corresponding position.The contents of moisture,total ash,acid-insoluble ash,water-soluble extract were 8.72%-11.61%,10.03%-18.31%,1.17%-5.91%,and 29.06%-37.16%,respectively.Conclusion The established standard can be used for quality evaluation of Yao medicine Violae inconspicuae herba.
