The explants were cultured on Murashige and Skoog (MS) medium containing different concentrations of growth regulators 6-benzylaminopurine (BAP) and Gibberellin (GA3).
Hydrodistillated EOs obtained from acclimatized and mother plant, were evaluated for their antioxidant activity. Tests were performed on DPPH free radical-scavenging, ABTS and CUPRAC assays.
Shoot induction and multiplication were successfully carried out on MS medium supplemented with the following hormones combinations: 1 mg/l BAP, 1 mg/l GA3 and 0.5 mg/l BAP, 0.5 mg/l GA3, respectively. Stem length, nodes and leaves number measured from development
EO yield of acclimated plant varied between (0.88-1.49 ml/100 g dry matter) compared to wild plant (0.73 ml/100 g dry matter). The antioxidant potential of EOs from acclimated plant showed on DPPH free radical-scavenging, ABTS and CUPRAC assays values of (IC50: 4.18-24.93 mg/ml), (IC50: 0.51-1.56 mg/ml) and (A0.50: 0.34-2.71 mg/ml), respectively. In contrast, the wild plant exhibited on the same tests the values of (IC50: 10.35 mg/ml), (IC50: 0.12 mg/ml) and (A0.50: 0.99 mg/ml), respectively.
The results suggest that micropropagation of
