    Anise oil was successfully able to be extracted from anise seeds during this experiment. It was done by first crushing the seeds‚ then placing them into a distillation apparatus. The distillation apparatus evaporated the liquid from the seeds‚ which was captured in a flask. Next‚ DCM was added to the distillate‚ which allowed the water to be separated from the anise oil. Finally‚ the DCM evaporated and the pure anise oil was collected. The process of steam distillation allowed the anise oil in the

    with the chemical composition of essential oil from the fruits of Solanum erianthum‚ a species extensively used in traditional medicine. The essential oil from fruits was extracted by hydrodistillation and the chemical composition of the essential oil was analyzed by gas chromatography-mass spectrometry (GC-MS). The yield of essential oil based on the dry weight of the plant was 0.05 % (v/w). Twenty two compounds accounting for 99.2 % of the total oil were identified. The main compounds were 9
