G. elliptica

Early investigations indicated the presence of an alkaloid in G. fremontii and G. racemosa. Six species were examined recently by Oneto, who found no alkaloid in G. jiavescens, amorphous bases in G. fremontii and G. buxifolia, and alkaloids yielding crystalline hydrochlorides in G. elliptica, G. wrightii and G. veatchii. The bark of the last-mentioned species was worked up for total alkaloids, which on fractionation yielded two crystalline bases. 

G. flavescens S. Wats, did not contain alkaloids, while G. buxifoUa A. Gray and G. fremontii Torr. yielded only an amorphous base mixture. G. elliptica Dough, G. wrightii Torr., and G. veatchii Kellogg yielded crystal-...
