ABSTRACT

The essential oil obtained by hydro-distillation of the aerial parts of Malva sylvestris L. were analyzed by GC and GC/Ms. The oil was characterized by higher amounts of 1, 8-cineol (18.27%), α-terpinyl acetate (14.8%), α-cadinol (11.5%) which was among the twenty-three components comprising 95.5% of the total oil detected. The Ether extract of the same plant (aerial parts of Malva sylvestris) was also analyzed by GC and GC/MS. The oil from the Ether extract was characterized by higher amounts of 1, 8-cineol (23.4%), α-terpinyl acetate (20.0%), α-cadinol (11.7%) and γ-cadinene (9.0%) were among the 18 constituents representing 89.8% of the total oil detected. The aim of present study was to identification of naturally occurring non-polar compounds by two methods (Water-distilled hydrodistillation and Ether extraction) from the aerial parts of Malva sylvestris L. which has been collected in Khalkhal, west- Azarbayjan, Iran, 2014. The anti-bacterial activations of the aerial parts by hydrodistillation and ether extraction of Malva sylvestris using MIC method. The growth inhibitory zone (mm) was also measured.
