Table 3 Yield, and scavenging and chelating activities of A. herba-alba essential oils

From: Essential oil variation in wild populations of Artemisia saharae (Asteraceae) from Tunisia: chemical composition, antibacterial and antioxidant properties

  1. Values represent mean ± standard deviation (n = 5). Values followed by the same letter under the same row, are not significantly different (p > 0.05). Oil yield was expressed in ml/100 g dry matter. DPPH radical-scavenging activity (%) was determined for essential oil concentration at 1 mg/ml. Metal (Fe2+) chelating activity was presented as IC50 values (mg/ml). Coding numbers of altitudinal populations: see Table 1.
