Variation on the Chemical Composition of the Oil from Damaged Branches of Guarea guidonia (L.) Sleumer (Meliaceae)

Abstract The damaged branches of one specimen of Guarea guidonia, which had been blown down after a high wind, were submitted to steam distillation. The oil was analyzed by GC and GC/MS. The chromatographic profile indicated a difference in the composition of this oil in comparison to an oil obtained from healthy-branch oil analyzed previously The crude oil was thus submitted to chromatographic separation, and the main components identified by NMR and GC/MS.
