Two new sesquiterpene alkaloids, peritassines a [1] and B [2], and the known compounds euonine [3], ebenifoline W-I [4], euojaponine F [5], and wilforine [6], were isolated from the stems and bark of Peritassa compta. The structures of 1 and 2 were elucidated by high resolution nmr spectroscopy. © 1993, American Chemical Society. All rights reserved.
