Abstract:


Background: Atractylis gummifera is a cosmopolitan species that is particularly abundant in the Mediterranean regions. It has been used to treat many diseases, including intestinal parasites, ulcers, snakebite poisoning, hydrops and drowsiness. As part of our research program on natural compounds with biological activities, the objective of this study was to determine for the first time the chemical composition and biological activities of essential oils of Atractylis gummifera during beginning of the vegetative cycle (March), beginning of the flowering stage (April) and full bloom (May/June)

Methods: Atractylis gummifera is a cosmopolitan species that is particularly abundant in the Mediterranean regions. It has been used to treat many diseases, including intestinal parasites, ulcers, snakebite poisoning, hydrops and drowsiness. As part of our research program on natural compounds with biological activities, the objective of this study was to determine for the first time the chemical composition and biological activities of essential oils of Atractylis gummifera during beginning of the vegetative cycle (March), beginning of the flowering stage (April) and full bloom (May/June)

Results: The essential oil produced from the plant taken at the beginning of the vegetative cycle (March) had a high level of non-terpenic aliphatic compounds. On the other hand, the essential oil ob-tained during the period from the beginning of the flowering stage (April) showed that its proportion of non-terpene compounds decreased and that of sesquiterpene compounds increased. Finally, the essentialoils obtained during the period from full bloom (May/June) consisted mainly of acetylene compounds such as carlina oxide and 13-methoxy carlina oxide. The results showed that essential oils from plants at full bloom presented interesting antioxidant and antifungal properties, while essential oil produced from plants at the beginning of the vegetative cycle (Mars) and at the beginning of the flowering stage (April) had better insecticidal activity.

Conclusion: The data presented here constitutes new findings in the field of the chemical characteriza-tion and biological potential of A. gummifera
