Volatile Constituents of the Fruits ofClusia nemorasaG.Mey. from Different Region of Atlantic Coast restingas of Pernambuco (Northeast of Brazil)

The volatile components of the fruits from nine collections of Clusia nemorosa G. Mey. from two municipalities (Tamandare: 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- dare (T1–3) and Fortress Nazare (N1–3) and in the samples from Gaibu (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 Tamandare (T1–3: 20.4—22.0%) and Gaibu (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 Pe...
