The ethyl acetate was removed from the remainder of the solution by evaporation and the yellow residue was taken up in alcohol.
It was shaken out with ethyl acetate which became colored yellow.
It is insoluble in light petroleum, and but slightly soluble in ethyl acetate, water, or carbon bisulphide.
An action suitable for the purpose is the saponification of an ester, such as ethyl acetate.
A portion of the ethyl acetate solution gave an orange red precipitate with lead acetate showing the presence of fisetin.
