I do amatuer chemistry. Could anyone please help me on a procedure to extract apiole from parsley oil? Wikipedia says "In 1715, the Leipzig pharmacist Heinrich Christoph Link discovered apiol during the steam distillation of parsley oil." and "Heinrich Christoph Link, an apothecary in Leipzig, discovered the substance in 1715 as greenish crystals reduced by steam from oil of parsley.". I assume" reduced by steam" means steam distillation, but I don't really see where in the process of steam distillation of parsley oil (which has already been steam distilled from parsley) will crystallize out apiole..
I am very confused. Some guidance would be appreciated.
