Thin-layer chromatography to take the product powder 5g, chloroform 10ml reflux for 15min, filtered. The filtrate was concentrated to 2 ml for spotting. At the same time, linoleic acid chloroform solution was used as the control solution. The sample was spotted on the same silica gel H-1% CMC sheet, developed with benzene-ethyl acetate (8:2), sprayed with 0.1% α-nitroso-β-naphthol concentrated sulfuric acid reagent, and heated.
