ResumoThe EtOH extract from the leaves of Oxandra sessiliflora R. E. Fries (Annonaceae) was partitioned using hexane and CH2Cl2. After several chromatographic steps, caryophyllene oxide and spathulenol were isolated from hexane phase while, from CH2Cl2 phase, we isolated (E)-phytol, spathulenol, 4β,10α-dihydroxyaromadendrane, 1β,6α-dihydroxyeudesm-4(15)-ene, and 4α,7β,10α-trihydroxyguai-5-ene, the latter being a new sesquiterpene derivative. Additionally, a mixture of steroids (campesterol, sitosterol, and stigmasterol) was obtained from the CH2Cl2 phase. The isolated compounds were characterized by mass spectrometry and analysis of their 1H and 13C NMR spectroscopic data, including bidimensional analysis.
