Antioxidant Enzyme Activities of Some Wild and Cultivated Edible Mushrooms in Turkey

Abstract

were obtained from different locations in Turkey. Phenylalanine ammonia lyase (PAL) enzyme activity, ascorbate peroxidase (APX), peroxidase (POD), and superoxide dismutase (SOD) activity changes and nitrate, β-carotene and lycopene levels were investigated in 15 samples to determine antioxidant enzyme capacity. As a result of the study, the highest amount of β-carotene and lycopene were determined in H. erinaceus. P. ostreatus-2 had the lowest amount of β-carotene, whereas Pleurotus ostreatus-1 had the lowest amount of lycopene. Species rich in nitrate content were C. cornucopioides and P. ostreatus-4. P. ostreatus-3 was the poorest species in terms of nitrate compared to other mushroom samples. PAL activity of mushrooms varied between 5.863 and 8.893 EU mg -1 protein. For APX values, P. ostreatus-4 had the highest value, while H. erinaceus species had the lowest value. Among mushroom species, the highest and the lowest POD values were determined in H. erinaceus and B. edulis, respectively. C. cornucopioides had the highest and P. ostreatus-3 had the lowest SOD values.

A Bioactive Compounds Profile Present in the Selected Wood Rot

“…Jayakumar et al [78] determined β-carotene in a 5-fold higher concentration than the present study. Robaszkiewicz et al [79], Jaworska et al [80], and Turfan et al [81] found lycopene presence in addition to β-carotene. The latter was present at a much lower concentration in P. ostreatus.…”
