Abstract

Several species of cedar genus known as medicinal plants are used in traditional medicine. The study of various plants in order to identify Natural compounds with medicinal value is of interest to researchers. The aim of this study is to identify the chemical volatile compounds of cedar leaf extract, and to measurement the antibacterial effect of Cedar leaf extracts on Escherichia coli and Staphylococcus aurous and its allopathic effect on seedlings of wheat, barley and sesame. The completely randomized experimental design with four replications was chosen to consider. The results showed the existence of 16 different volatile compounds in the extract. Di epi alpha cedrene overall (45. 85%) and alpha pinene (12. 52%) were the most volatile compounds in the extract. The Allelopathy results showed that the 100(g/ L) concentrations of cedar leaf extract, wheat and sesame seed germination stops completely. In Concentrations of 50 and 25 (g/ L) leaf extract of cedar, seeds of three species were able to germinate. In wheat and barley, with increasing concentration, length and weight of shoot and root was significantly reduced. In Sesame with increasing in the concentration of the extract a significant change in the length and weight of shoot and root weren’ t observed. The results showed that cedar leaf extract has Antibacterial properties. It has more inhibitory effect on Staphylococcus aureus. Percentage inhibition for Staphylococcus aureus and Escherichia coli were 27% and 96%, respectively. Allelopathic potential of different volatile compounds of Cedar leaf extracts can be used to produce of natural and environmentally friendly herbicides. Cedar leaf extract has significant Antibacterial properties. Its inhibitory effect could be evaluated against human pathogenic bacteria and could be used as a source of natural antibiotics.
