Background and objectives:Ornithogalum procerum Stapf. (Family: Liliaceae) is an Iranian
medicinal plant found mainly in the east Azarbaiijan province of Iran. As part of our ongoing
phytochemical and bioactivity studies on medicinal plants from Iranian flora, various
extracts and essential oils of this plant were analysed by GC-MS.
Methods: The hydrodistillation of the ground aerial parts of O. procerum, Soxhletextraction
of the dried and ground bulbs, and the hydrolysis of the methanol extract of the
bulbs yielded, the essential oils, n-hexane extrcat and the hydrolysed methanolic extract
respectively, which were analysed by the GC-MS.
Results:A total of 23 compounds were identified from the essential oils of the the aerial
parts. The identified compounds represented 70.27% of the total essential oils. The main
components of the aerial parts were phenylacetaldehyde (7.57%), hexahydrofarnesyl
acetone (8.13%), docosan (5.52%) and 5-methyl octadecane (4.63%). From the n-hexan
extract of the bulbs, seven hydrocarbons representing 99.39% of the total extract, were
identified. Finally, from the hydrolyzed methanolic extract of the bulbs, four polysteroltype
compounds accounting for 59.81% of the extract, were detected.
Conclusion: The GC-MS analyses reavealed that the essential oils are mainly composed of
oxygenated hydrocarbons, the n-hexane extract contains predominatly hydrocarbons, and
the hydrolyzed methanolic extract comprises polysterol-type compounds.
