In preceding communications [1, 2] we have described results of an investigation of the alkaloids of the epigeal part of V. lobelianum. From the hypogeal part of this plant by chloroform extraction we have obtained 1.01% of combined ethereal and 0.8% of combined chloroformic bases (on the weight of the dry raw material). We treated the combined ethereal bases with benzene, separated the precipitate on an alumina column, and eluted with benzene and chloroform to yield base (I) identified as germerine. The benzene-soluble fraction was partitioned and separated to obtain veratroylzygadenine (III), jervine (IV), veralosinine (VI), and other bases. The combined chloroformic alkaloids were treated to yield pseudojervine (VIII) and other bases. Thus, of the total bases of the hypogeal part of V. lobellanum we have isolated the following known alkaloids -germerine, veratroylzygadenine, jervine, and pseudojervine -and, as new alkaloids, veralosinine and three bases -(II), (V), and (VII) -the study of which is continuing.
