Using Vegetable oil as a non-polar Solvent in Plant extraction

So in recent times an increase in the use of green solvents has become popular. More and more papers are experimenting with these solvents in place of others. Vegetable oil can be used to extract alkaloids from plant material as a non-polar. With the help of sodium carbonate which can be made by heating sodium bicarbonate in the oven to make a alkaline aqueous layer with the plant material to free the alkaloids. The free alkaloids will move to the non-polar vegetable oil. You then salt the alkaloids with vinegar and evaporate. You get a crude extract but purity will be higher than a residue tar from simple water extract. Isopropanol is possibly able to clean up the tar even at 70% concentration which is what is most accessible. Sodium acetate is almost insoluble in 1-propanol and 2-propanol is basically the same. https://pubs.acs.org/doi/10.1021/je40...
