OBJECTIVE
To study the effect of abamectin on the content of Lycium barbarum polysaccharide (LBP).
METHODS
The Lycium barbarum plant was sprayed by 2% abamectin EC, while they were endangered by Aceria macrodonis Keifer. Then the samples of Lycium barbarum were picked periodically. LBP was extracted by phenol-sulfuric acid method and its content was measured by spectrophotometry method.
RESULTS
The content of LBP increased in the 0-5 days after pesticide application and reached the peak at the 5th day; 10 days later, the content reduced to the minimum. It was close to the control sample after 21 days. LBP Content in samples were obviously higher than that of the control.
CONCLUSION
Abamectin has some effects on the content of LBP.
目的
研究阿维菌素对枸杞多糖（LBP）含量的影响。
方法
用2%阿维菌素乳油喷洒受枸杞瘿螨侵害的枸杞植株，定期采集枸杞样本。采用苯酚-硫酸法提取LBP，用分光光度法测定其含量。
结果
施药后0-5天LBP含量增加，第5天达到峰值；10天后，含量降至最低。21天后接近对照样本。样本中LBP含量明显高于对照。
结论
阿维菌素对LBP含量有一定影响。
