Abstract
The changes on these seeds during storage: total oil, volatile oil, and the major components of volatile oils were determined. A decrease in the total and volatile oils and all components of volatile oils were found. The components of volatile oils during growing periods were studied. Three samples, first at (1/ May), second (15/ June), third (15/ July) were taken. The experiment found that the total and volatile oils were increased during growing stages. The same results for major compounds of volatile oils were found.
Major compounds of volatile oils were found at (1/ May)except Linalool and Anisaldehyde were absent. The results showed that the best time of harvesting for aniseed was at the last stage of growing when these seeds began dry, but not absolute dry, because this could decrease the component of the total and volatile oils and their compounds. The seeds should be dried away from sun rays to save its components.
