摘要: The essential oil of an endemic species, Pinus armandii, gathered from China, was extracted by hydrodistillation and solid phase micro-extraction (SPME). The oils have been studied by GC and GC-MS. A total of 57 compounds have been identified in the pine cone oil extracted by hydrodistillation, the principal components being alpha-pinene (20.92%) and D-limonene (15.78%), beta-pinene (4.91%) and transpinocarveol (4.76%), while the oil extracted by SPME showed alpha-pinene (41.59%), D-limonene (17.8%), beta-caryophllene (11.02%) and beta-pinene (7.54%) as the principal components. SPME extracts indicated that alpha-pinene and beta-caryophllene were in greater concentration in the head space vapours than in the oil. The antioxidant activity of the oils from P. armandii was evaluated using the DPPH. This is the first report describing the essential oil composition and antioxidant activity of this species.
