In this article we aimed to determine skin protective and antimicrobial effects of different extracts from the roots and aerial parts of three Scorzonera species (S. hieraciifolia, S. hispanica, S. tomentosa). Antimicrobial properties were evaluated against different pathogen bacterial and fungal strains, whereas protective effects were studied in isolated mouse skin specimens exposed to hydrogen peroxide. In this biological model, the levels of l-dopa and prostaglandin E2 (PGE2) were evaluated, as markers of tyrosinase activity and inflammation, respectively. All extracts were effective in blunting the increased hydrogen peroxide-induced l-dopa turnover and PGE2 level; thus, suggesting skin protection that could be partly related to the content of flavonoids, among which rutin, in the tested extracts. Additionally, all extracts were effective as antibacterial and antifungal agents; intriguing results were observed against Trichoderma viride, which was particularly sensitive to S. tomentosa root extracts. Therefore, the present study strengthens the importance of investigating herbal preparations obtained from plants belonging to the genus Scorzonera, for the management and prevention of inflammatory and infectious skin conditions. |
