A wide variety of alkaloids has been encountered in the bark of Aspidosperma quebrachoblanco (see Table I). An investigation of the leaf alkaloids yielded a new base, quebrachidine (CCCXXXVIII-D, 179b), whose UV- (A 242, 290) and NMR-spectra were indicative of a dihydroindole unsubstituted in the benzene ring, while the IR-spectrum showed the presence also of the groupings NH, OH, and CO2R.
