Abstract

Sedum genus includes more than 400 different species, many of which having ethnobotany interest. The skin healing is one of the most common therapeutic indication of Sedum spp. In this work, for the first time, we compared five different Sedum species grown in two sites of community importance in Emilia Romagna (Italy): Sedum acre L., Sedum album L., Sedum hispanicum L., Sedum rupestre L. and Sedum sexangulare L., analysing their total phenolic and flavonoid content, their antiradical capacity and the in vitro healing activity on human keratinocytes. Total phenolic content of the five species ranged from 35.41 ± 1.18 to 90.22 ± 1.03 mg gallic acid equivalent/mg of dry extract, being S. rupestre the richest one. Total flavonoid content ranged from 22.39 ± 0.51 to 47.93 ± 2.82 mg rutin equivalent/mg of extract and S. album resulted the species with the highest flavonoid content. Antiradical capacity was found to be related to the phenolic content of the extracts. All the extracts were active in wound healing assay and each one showed different kinetic of action and concentration-activity relationship. This study proposes few investigated Sedum species grown in Italy as promising agents for skin healing and suggests further phytochemical and biological investigations.
