Description

Extraction of cuticular compounds from individual bee specimens using n-pentane solvent followed by gas chromatographic analysis with flame ionization detection for chemical profile characterization. Includes compound identification via GC-MS and structural elucidation using mass spectral libraries.

Typical Equipment

• n-pentane (Uvasol, 99.5%, Merck, Germany)
• nitrogen stream
• Agilent 7820 A Series gas chromatograph
• DB-5 MS capillary column
• flame ionization detector
• HP 6890 series gas chromatograph-mass spectrometer
• AMDIS 2.71 software
• NIST11 library
• solid-phase extraction equipment
• dimethyl disulfide (DMDS)

Output Measurements

• cuticular chemical profiles
• relative compound abundances
• compound identifications
