Abstract: | The investigation of essential oil of all species belonging to the Thymeleaceae family is very poor especially the genus Thymelea . In Algeria it is represented by 7 species. Thymelea species are reported to be medicinal plants in the literature as well as in folklore, and their medicinal values are well documented. Their properties are attributed to a variety of active phytochemical constituents Essential oil components of the aerial parts of Thymelea microphyla Coss et Dur. have been studied by gas chromatography-mass spectrometry to afford 11 components. The major components were found to be: D-menthone (41.86 %), 2- Undecanone (23.74 %), Pulegone(11.94%) and Perillal (9.34 %). Some other compounds were only present in minor amounts. In total, volatile oil composition of Thymelea microphyla Coss et Dur. was considered as a rich source of oxygenated monoterpenes . The antioxidant activity were evaluated by spectroscopic dohtem , used for that free radical compound (DPPH) and in comparison with a reference(vitamin C ). The crude extract showed a good activity against free radical compound (DPPH) . The antimicrobial activities of essential oil were evaluated by disc diffusion method and tested against Gram-positive and Gramnegative bacteria and showed a strong antibacterial activity against Staphylococcus aureus, Escherichia coli and Klebsiella pneumonia |
