This experiment was performed over three years. The first year was with four students working in two pairs. One pair extracted spearmint leaves, and the second pair extracted caraway seeds. The extraction was done by refluxing an amount of the natural product in dichloromethane for 30mins, cooling the suspension, and filtering to obtain the clear liquid for TLC and GC analysis. However, the filtration was problematic and took a longer than expected period. Additionally, even with careful filtration, the filtrate still shows solids deemed to be of high boiling point and posing a danger to the durability of the GC columns. In the second and third years, we switched to steam distillation instead.
