气相色谱法测定小菜蛾性诱剂中3种有效成分

Determination of three effective components in sex pheromone lures of plutella xylostella by gas chromatography

采用气相色谱法建立了小菜蛾性诱剂中3种成分顺-11-十六碳烯醛、顺-11-十六碳烯酯和顺-11-十六碳烯醇的测定方法。通过实验优化了色谱条件,考察了方法的精密度和准确度。结果表明,3种组分的标准曲线均呈现良好的线性关系,相关系数均大于0.999,方法的加标回收率在94.5%~97.5%之间,方法的准确性可以满足实际分析的需要,对开展小菜蛾性诱剂中各成分的定量分析具有重要意义。

The determined effective components are(Z)-11-hexadecenal,(Z)-11-hexadecenylacetate and(Z)-11-Hexadecanol.Their linear relation are good,the correlation coefficients are more than 0.999,the average recoveries range from 94.5%to 97.5%.The accuracy of the method can satisfy the analytic requirement for the sex pheromone lures of Plutella xylostella.
