SPECTROPHOTOMETRIC EVALUATION OF PHOTOPROTECTIVE AND ANTIOXIDANT PROPERTIES OF EX-TRACTS FROM THE CULTURED MUSHROOMS FRUIT BODIES

The article presents the results of a spectrophotometric evaluation of the photoprotective and antioxidant properties of hexane, methanol and acetone extracts from the fruit bodies of cultivated mushrooms Ganoderma lucidum, Hericium erinaceus, Lentinula edodes and Pleurotus ostreatus, which were obtained by sequential and direct extraction methods. For the extracts, the values of the sun protection factor and the critical wavelength, the content of flavonoids, and DPPH (2,2-Diphenyl-1-Picrylhydrazyl) radical scavenging activity and β-carotene bleaching assay were evaluated. The largest mass of extracts is obtained using methanol (12.2–19.4%), the smallest – hexane (1.7–4.1%). For hexane and acetone extracts from H. erinaceus and P. ostreatus, high levels of SPF were found: 29.3±2.34; 22.7±1.63 and 14.7±1.32; 18.4±1.37, respectively. Mushroom extracts with high SPF values are not photoprotective, as they absorb UV-A weakly (λcrit<370nm). The highest content of flavonoids was found for methanol extracts from G. lucidum and H. erinaceus. In terms of percentage inhibition of DPPH and oxidation of β-carotene, the antioxidant activity of methanol extracts from G. lucidum, H. erinaceus, and P. ostreatus is comparable to the antioxidant activity of α-tocopherol. It can be concluded that extracts from these mushroom species can be used as photoprotective and antioxidant additives in the development of sunscreen formulations.
