Portulaca oleracea extracts protect human keratinocytes and fibroblasts from UV-induced apoptosis

摘要

Portulaca oleracea extracts, known as Ma Chi Hyun in the traditional Korean medicine, show a variety of biomedical efficacies including those in anti-inflammation and anti-allergy. In this study, we investigate the protective activity of the P.oleracea extracts against UVB-induced damage in human epithelial keratinocytes and fibroblasts by several apoptosis-related tests. The results suggest that P.oleracea extracts have protective effects from UVB-induced apoptosis.
