Volatile constituents of Jasminum humile L.

The essential oil was obtained by hexan. The sample oil, which was light yellow in color, was dried over anhydrous sodium sulfate and stored under nitrogen in a sealed vial until required. The oil obtained was analyzed by GC-MS and GC/MS. The components of the oil were identified by comparison of their mass spectra to those of a computer library or with authentic compounds and confirmed by comparison of their retention indices, either those of authentic compounds or data published in the literature. The essential oil wasisolated by steam distillation from flowers of cultivated Jasminum humile in Iran. It was analyzed by GC-MS and GC/MS. Among eighteen identified compounds, the major components were (Z)-?-ocimene (27.7%), p-cymene (13.3%), ?-pinene (13.1%) and carvone (12.2%). Other compounds present in appreciable amounts are ?-terpinene (8.4%), fenchol (7.3%), linalool (6.1%) and fenchone (3.6%).
