CHEMICAL COMPOSITION OF ESSENTIAL OIL OF NECTAROSCORDUM TRIPEDALE (TRAUTV.) GROSSH. FROM IRAN

چکیده مقاله

Nectaroscordum tripedale (Trautv.) Grossh. is a weedy plant from liliaceae family.Summery onion (N. tripedale)have boll and tall strong stem with 50 to 150 cm length that in the head have umbel inflorescence [1]. We collect N. tripedale from the origin of this plant in DarrehShahr city in zagrosfoot a mountain, Iran, in March 2015. We evaporate plant in shadow and extract essential oil by SDE and analyze by gas chromatography (GC) and gas chromatography/mass spectrometry (GC/MS). Identification of the components was based on GC retention index computer matching with Wiley GC/MS library, and by comparison of the fragmentation patterns of the mass spectra with those reported in the literature [2]. GC and GC/MS analyze of the essential oil showed 72constituents were identified, of which the major ones, transanethole (23.67%), Methyl dodecanoate (16.46%), Dimethyl trisulfide (7.04%) and dibutyl phtalate (4.75%) accounted for 51.92% of the oil.
