The material used in this investigation consisted of fresh fruits collected from Thana (near Bombay), and dried in air. The material was ground and successively extracted with petroleum ether and alcohol. From the petroleum ether extract were obtained: (1) an oil, and (2) a sterol C36H54O4, m.p. 248°C., designated "carpesterol". From the alcoholic extract were obtained: (1) a gluco-alkaloid C44H77O19N, m.p. 288-89°C. (decomp.) named "solancarpine," (2) an alkaloid C26H43O3N, m.p. 197-98°C. named "solancarpidine," (3) sugars: (i) glucose, (ii) rhamnose, and (iii) a hexose, probably galactose, and (4) an inorganic salt "potassium chloride". One of us (I. Z. S.) takes this opportunity to express his sincere thanks to Principal Dr. T. S. Wheeler for his keen interest and valuable assistance.
