Chemical composition of the essential oils of Annona cuneata L. and Annona senegalensis Pers. stem barks

The composition of the essential oils of the Annona senegalensis Pers. and Annoa cuneata L. (Annonaceae) stem barks is reported. GC and GC-MS analyses showed p-cymene (36.0%) as the most abundant component of A. senegalensis, whilst sabinene (39.9%) was the main component of A. cuneata. alpha-and beta-Pinene, (5.1% and 9.2%), beta-phellandrene (4.9%), limonene (5.8%) and germacrene D (9.0%), were the major constituents of A. cuneata; those of A. senegalensis stem bark oil were alpha-phellandrene (25.0%), alpha-pinene (8.3%), Z-sabinol (6.9%) and limonene (4.8%).
