Abstract
A solid phase extraction technique was developed to aid in removing interfering substances from the cockroach brain extract. Quantitative analysis of octopamine was subsequently achieved by HPLC with amperometric electrochemical detection. The procedure affords 80 to 100 percent recovery of octopamine. The presence of octopamine in brain extract was confirmed by GC-MS.
The daily pattern of brain octopamine levels in cockroach Leucophaea maderae was investigated using the HPLC-EC assay procedure. It was concluded that the concentration of brain octopamine in the cockroach L. maderae does not exhibit daily rhythm.
