Résumé :	The volatile components of the fruits from nine collections of Clusia nemorosa G. Mey. from two municipalities (Tamandaré: T1–3 and Cabo de Santo Agostinho: N1–3; G1–3) of the coastal region of Pernambuco, Northeast of Brazil, in two kind of soil, rocky rich in iron (N1–3) and sandy clays (T1–3 and G1–3), were analyzed by GC and GC/MS. The isolated oils were obtained in similar yields, 0.1–0.3 % (w/w) and 0.1–0.2% (w/w) in the samples from Taman- daré (T1–3) and Fortress Nazaré (N1–3) and in the samples from Gaibú (G1–3), respectively. The oil samples can be characterized by the abundance of sesquiterpene hydrocarbons, while the percentage of oxygenated sesquiterpenes was higher in the samples collected in Tamandaré (T1–3: 20.4—22.0%) and Gaibú (G1–3: 17.6–20.4%). Monoterpenes hydrocarbons were totally absent in all samples. All samples showed β-caryophyllene (37.3–48.6%) as the principal component. Based on the information of other major components, two subtypes of C. nemorosa growing wild in Pernambuco, Brazil, can be established.
