실험 절차
0.05 g (10% wt) of K3PO4 and 0.05 g (10% wt) of polyethylene glycol (PEG 400) were added to 0.5 g of the spilanthol mixture (αβ unsaturated form:βγ unsaturated form=43:57) obtained in the above-mentioned (7), followed by stirring at 80° C. for 16 hours. When verified by GC, the ratio of αβ unsaturated form to βγ unsaturated form was converted to αβ unsaturated form:βγ unsaturated form=99:1. After cooling of the reaction liquid and subsequent separation of liquid by adding 5 ml of toluene and 5 ml of water, the organic layer was subjected to solvent evaporation under a reduced pressure to obtain 0.5 g of the target spilanthol (yield 99%, αβ unsaturated form:βγ unsaturated form=99:1).
