RESUMEN
Objective: To evaluate chemical compositions, antioxidant and wound healing properties of Algerian Artemisia absinthium essential oil.Methods: The chemical composition of the essential oil from Artemisia absinthium was analyzed by a combination of GC-FID and GC/MS. The antioxidant capacities including the total antioxidant capacity, DPPH? and ABTS+? scavenging capacities were measured. The wound healing potential was assessed by the excision wound model of rats. The wounds were treated daily with an ointment prepared with two concentrations (5％ and 10％) of Artemisia absinthium essential oil. The percentage of wound contraction was determined and wound healing was also evaluated by histological examination of the healed skin. Results: The main component of Artemisia absinthium essential oil was camphor (48％) followed by chamazulene (10％) that was responsible for the dark blue color of the oil. Artemisia absinthium essential oil exhibited moderate antioxidant activity compared with BHT and Trolox. All preparations showed significant effects on wound contraction and the ointment prepared with 10％ of essential oil was effective as the reference drug Cicatryl. Conclusions: The essential oil of Artemisia absinthium shows moderate antioxidant activity. The 10％ ointment enhances skin wound re-epithelialization and speeds up the healing process. The essential oil of Artemisia absinthium may be used as an alternative drug for wound healing.
