摘要：
An investigation of nitrogen-containing compounds in black pepper oil, by capillary GC, GC/MS and HPLC techniques, revealed 20 previously unreported pyrazines, pyridines and piperidines. These species were found to be present at levels ranging from 1.50 ppb to 30 ppm. Odor assessment revealed that 2-ethyl-3,5-dimethylpyrazine (1.5 ppm) and 3-ethyl-2,5-dimethylpyrazine (490 ppb) contributed most significantly to the overall odor.
