5%天然除虫菊素微囊剂的分析方法探索

Analytical Method for 5% Pyrethrins-CS

天然除虫菊素(pyrethrins)是从除虫菊(Pyrethrum cinerifolium Trebr)中提取出来的活性成分。它是6种杀虫成分的混合物,各有效成分的分离和定量分析就存在一定的难度,将其制成微囊制剂后,定量分析的难度进一步提高。本文在文献的基础上建立了CGC法对5%天然除虫菊素微囊剂中各有效分离。与经典的AOAC方法相比,显得更科学、快捷,为工业化生产的质量检测提供了可靠的保障。

5% pyrethrins-CS inelouds six insecticidal components. It is difficult to analyze the six components. A CGC method using OV- 101 column （4m×0.25 mm × 0.25μm）, taking program temperature was developed, to analyze 5% pyrethrins-CS in this paper. So the separation of the six effective components was realized. Compare to AOAC method, the result showed that this method was scientific and fast. it can be used for industrialized determination.
