Abstract
Three alkaloids, termed a -, b -, and g -lobeline, are isolated from the crude alkaloid of lobelia inflata by dissolving the crude product in hydrochloric acid, crystallizing out the difficulty-soluble hydrochloride of b -lobeline, and extracting the hydrochloride of a -lobeline, from the mother-liquor by means of chloroform. The chloroform solution is mixed with soda solution, the chloroform evaporated off, and the a -lobeline crystallized out; it is formulated as C21H23O2N. The b - and g -lobeline are not crystalline. The crude alkaloid employed may be obtained by extracting the drug by alcohol, distilling off the alcohol, dissolving the bases in dilute acid, neutralizing the acid solutions by alkali and extracting with ether; or the first extract may be made with ether or benzene.
