[Effects of abamectin on the content of Lycium barbarum polysaccharide].
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.


CONCLUSIONS
Abamectin has some effects on the content of LBP.
