The essential oil of Verbena officinalis growing in Iran was extracted using hydro-distillationmethod and the antibacterial and antioxidant activities were evaluated. The antibacterial activity of the essentialoil against a Gram-positive (S. aureus ATCC25923) and Gram negative (E. coli ATCC 25922) were examined.The results obtained revealed that the essential oil exhibited variable levels of an...

butyl-hydroxytoluene (bht) is one of the major synthetic antioxidants with a wide range usage. replacement of artificial antioxidants with natural antioxidants is highly considered. in this research, the antioxidant activity of juniperus excelsa was investigated by using reducing power, dpph radical scavenging and inhibition of lipid peroxidation. also, the amounts of phenolic and flavonoid com...

background: in recent years, natural products, especially natural antioxidants, play an important role in various fields. in fact, lippia citriodora is one of the medicinal plants which is cultivated in iran and it may be has potential antioxidant activity. objective: the chemical composition of lippia citriodora essential oil (lceo) has been determined. the total phenolic content and antioxida...

This study represents the first report on the chemical composition and biological activity of Trifolium angustifolium var. angustifolium. The major components of the essential oil were identified as hexatriacontene (23.0%), arachidic acid (15.5%) and α-selinene (10.0%). The main constituents of the fatty acid obtained from the petroleum ether extract were identified as palmitic acid (29.8%), li...
