Résumé :	"The chemical study of secondary metabolites of the species Biscutella raphanifolia collected from Constantine and Zilla macroptera from the region of Ghardaia, allowed, by the use of different methods of extraction and separation, the isolation of twenty products from which ten were identified including, four isolated from the n-butanol extract of Biscutella raphanifolia and seven from the n-butanol extract of Zilla macroptera. GC and GC/MS analyses of the essential oil of fresh aerial parts of Inula graveolens species showed that it is mainly characterized by isobornyl acetate (50.8%), borneol (18.3%) and t- cadinol (6.2%). GC and GC/MS analyses of the essential oils of fresh aerial parts of Inula viscosa collected from two different regions are mainly represented by nerolidol (25.3%), isocosticacid (10.1%), costicacid (8.0%), neo-intermedeol (6.4%) and caryophyllene oxide (5.5%) for the plant collected at Ain El-Bey (South Constantine) and by isocostic acid(25.1%), costic acid (15.2%), nerolidol (9.6%), linoleic acid (9.1%), neo-intermedeol (7.5%) and fokienol (7.2%) for the plant collected at Hamma Bouzianne (Northern Constantine). The investigation of the biological activities of eight extracts of these two species showed that the ethyl acetate extract exhibited the best antioxidant activity which may be due to the presence of phenolic compounds in polar extracts. Petroleum ether extracts showed the best anti-cholinesterase activity. The petroleum ether extract of Biscutella raphanifolia exhibited the best antibacterial activity against ETEC, EPEC and Enterococcus faecalis, while the EHEC strain was more sensitive to the dichloromethane extract. The essential oils of Inula viscosa showed the best activity against Pseudomonas aeruginosa and Klebsiella pneumoniae."
