Capillary electrophoresis of pterin derivatives responsible for the warning coloration of Heteroptera
Original language description
A new capillary electrophoretic (CE) method has been developed for analysis of 10 selected derivatives of pterin that can occur in the integument (cuticle) of true bugs (Insecta: Hemiptera: Heteroptera), specifically L-sepiapterin, 7,8-dihydroxanthopterin, 6-biopterin, D-neopterin, pterin, isoxanthopterin, leucopterin, xanthopterin, erythropterin and pterin-6-carboxylic acid. Pterin derivatives are responsible for the characteristic warning coloration of some Heteroptera and other insects, signaling noxiousness or unpalatability and are used to discourage potential predators from attacking. Regression analysis defining the parameters significantly affecting CE separation was used to optimize the system (the background electrolyte (BGE) composition, pHvalue and applied voltage). The optimized separation conditions were as follows: BGE with composition 2 mmol L-1 the disodium salt of ethylendiamintetraacetic acid, 100 mmol L-1 tris(hydroxymethyl)aminomethane and 100 mmol L-1 boric acid,
