INTERRELATION BETWEEN CARBOXYLESTERASE AND
GLUTATHIONE-S-TRANSFERASE IN APRIONA GERMARI LARVAE
AND SECONDARY METABOLITES OF POPLAR TREES
摘要
Abstract
Activities of carboxylesterase and glutathioneStransferase in %Apriona germari% larvae which feeding on eight different kinds of poplar trees were tested.The results showed that the activities of the two enzymes were significantly different when the larvae feeding on different poplar trees.The contents of fourteen secondary metabolites in eight poplar trees were also tested with the method of highpressure liquid chromatography (HPLC).By cluster analysis the eight poplar trees were divided into groups.One group includes %P.canadensis,P.×euraericana% cv.“I214”,%P.×beijingensis,%J2 poplar,J1 poplar and%P.canadensis% cv.“Shanhaiguanensis”.The other group includes%P.tomentosa, P. alba% var.%pyramidalis.%Stepwise regression analysis was carried out to test the relationship between the activities of the above enzymes and secondary metabolites of poplar trees.The analysis result demonstrated that the contents of phenol and phyadroxybenzoic acid decreased together with the increase of carboxylesterase activity while the contents of syringic acid and chlorogenic acid increased,but the content of ferulic acid decreased together with increasing of glutathioneStransferase activity while the content of phenol in poplar trees increased.关键词
