Abstract

The paper describes the use of photochemiluminescence assay (PCL) and DPPH method for the measurement of lipid‐soluble antioxidants capacity (ACL) of six commercially available cold‐pressed, non‐refined flaxseed, walnut, rapeseed, pumpkin seed, evening primrose and black cumin oils. The cold‐pressed plant oils are rich in various valuable bioactive compounds, e.g., tocopherols, tocotrienols, carotenoids, sterols, phospholipids and may reveal the antioxidant properties. The photochemiluminescence analysis (PCL) and free radical scavenging activity toward DPPH. were fully applicable for the evaluation of the antioxidant capacity of lipophilic fraction of samples and the outcomes correlated (r = 0.91). The highest ACL exhibited black cumin oil in case of both methods.
