Antioxidant Capacity as a Marker for Assessing the In Vitro Performance of the Endangered Cistus heterophyllus

Figure 2

(a) Relationship between initial Na⁺ concentrations present in the basal media formulations used in this study and antioxidant activity displayed by C. heterophyllus extracts after 4 weeks of culture in liquid media. In (b) and (c) DPPH scavenging activity versus K⁺/Na⁺ and Ca²⁺/Na⁺ ratios, respectively, is shown.
