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.
