This study evaluated natural extracts from plant biomass for UV protection and oxidative stress reduction. Conducted in Bucharest, Romania, it focused on medicinal mushrooms and pomegranate bark. The biotechnological process involved a two-phase extraction: hot water processing of Ganoderma lucidum, Hericium erinaceus, Inonotus obliquus, and Tremella mushrooms, followed by ethanol extraction with pomegranate bark and green tea. The spectrophotometric analysis identified phenolics and flavonoids. The ethanol extract showed higher phenolic content and antioxidant activity, particularly in DPPH radical scavenging. UVB exposure tests demonstrated its protective effect, comparable to vitamin B3, delaying oxidative stress onset by 30 min. This research underscores the potential of using natural biomass extracts in skincare, promoting environmental sustainability and economic viability by converting agricultural waste into valuable bioactive compounds.
