首次建立了中药材中氯氰菊酯、氰戊菊酯和溴氰菊酯的提取、净化及其毛细管气相色谱测定法。运用混合溶剂提取，填有Ｆｌｏｒｉｓｉｌ和氧化铝的层析柱净化。样品中氯氰菊酯、氰戊菊酯和溴氰菊酯的添加回收率分别为９４．３０％～９９．３４％，９５．１７％～１０１．５５％和８９．１２％～１００．９７％；ＲＳＤ分别为４．０２％～８．２２％，１．９０％～８．０４％和３．７５％～５．０９％。结果表明，被测样品中除白芍外均含有氰戊菊酯，个别样品中含溴氰菊酯。实验表明，该法具有灵敏度高、选择性强、操作简便、净化效果好、适用性广等特点
For the first time, the extraction, purification and capillary gas chromatography of cypermethrin, fenvalerate and deltamethrin in traditional Chinese medicine were established. Extraction with mixed solvents, column packed with Florisil and alumina. The recovery rates of cypermethrin, fenvalerate and deltamethrin in samples were 94.30% ~ 99.34%, 95.17% ~ 101.55% and 89.12% ~ 100.97%, respectively. The RSD Respectively 4.02% ~ 8.22%, 1.90% ~ 8.04% and 3.75% ~ 5.09%. The results showed that fenvalerate was contained in all tested samples, except deltamethasone, and deltamethrin in some samples. Experiments show that the method has the characteristics of high sensitivity, strong selectivity, simple operation, good purification effect and wide applicability
