Quantitative Determination Of Main Components In The Aniseed Oil Through Growing Periods Of Anise Plant And Find The Time and Best Method For Drying Anise Plant Before Separation of The Seeds

In this research, 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.

Study of the Factors Effect on Cumin Seeds volatile Oil Components And Finding The Best Method For Drying Cumin Plant Before Separation of its Seeds

The identification of the cumin oil composition was determined qualitatively and quantitatively by GC, using standard compounds. The components of the cumin seed oil (Cuminaldehyde, p-cymen and β-penine) were matched with the standard compounds. The factors effect on some components of cumin seed volatile oil were studied. The effects of time and temperature on the cumin seeds components were studied, the results have been shown that the total oil and volatile oil and its main components decreases with the passing of time and with the increasing of temperature.
