Chemical Composition, Antimicrobial And Antioxidant Activities Of The Essential Oils Of Santolina Africana Flowers, Endemic In Algeria
Résumé: The essential oils obtained by hydrodistillation of the flowers of Santolina africana Jord. et Four. were analyzed by GC/MS. The main constituents of the essential oil were acenaphtane (25.23 %), calarene (21.54 %), ocimene (17.44 %) and some other compounds that were presented only in minor amounts. In total, essential oils of Santolina africana Jord. et Four. were considered as a rich source of hydrocarbon mono and sesquiterpenes. Moreover, the antimicrobial activity of the essential oil against eight bacteria strains and three fungi was studied. It was found that the most powerful effect was against Bacillus subtilis, Staphylococcus aureus and Aspergillus flavus. The essential oils were screened for their possible in vitro antioxidant activity by DPPH free radical-scavenging test. The findings showed that reduction percentage is 13.80 at 1M
