Copaifera multijuga Hayne is one of the Copaifera species from which copaiba oil is extracted. Employed in the composition of anti-inflammatory and antiseptic products used in phytotherapy, it is also used by the fragrance industry as a fixative in perfumes, cosmetics and in products such as soaps. To identify the active aroma compounds in C. multijuga oil bouquet, GC-O-MS using AEDA (Aroma Extract Dilution Analysis) was used after the quantification of the components by GC-FID. The results obtained pointed to minor compounds such as delta-cadinene (1.9%, FD 64), delta-cadinol (0.9%, FD 128), (Z)-alpha-santalol (0.2%, FD 128) caryophyllene oxide (0.2%, FD 64), alpha-cadinol (0.1%, FD 128) and tau-muurolol (0.1%, FD 128) as the most intense compounds in the odor of the copaiba oil studied. Chiral GC-O-MS showed (+)-delta-cadinene as the only enantiomer present in the oil, with a sweet, green and refreshing aroma.
