Objectives : In order to confirm whether extracts of different parts of Zostera marina (ZM), a marine flowering plant, can be used as cosmetic ingredients, this study evaluated their cytotoxicity and cytoprotective effects against ultraviolet B (UVB). Inflammatory responses induced by UV stimuli are also associated with the aging of the skin.
Methods : We investigated the effects of ZM extracts on cells through the water soluble tetrazolium salt-1(WST-1) assay for cell viability. In order to investigate the anti-inflammatory effects, we evaluated the suppression of Cyclooxygenase-2 (COX-2) expression by ZM extracts in HaCaT cells with UVB-induced damages, and also evaluated the production of Prostaglandin E2 (PGE2) in RAW 264.7 cells with LPS-induced damages.
Results : High cell viabilities above 90% were observed in all types of ZM extracts, except for whole ZM extract at 0.5 mg/ml; in keratinocytes with UVB-induced damages, the cell viabilities were above 80% when treated with all types of ZM extracts. We confirmed their anti-inflammatory effects by investigating the suppression of inflammatory mediators. In keratinocytes with UVB-induced damages, COX-2 expression decreased in the experimental group treated with ZM extract. Similarly, in RAW 264.7 cells where inflammation was induced with LPS, the biosynthesis of PGE2 was inhibited.
Conclusion : These results suggest that ethanol extracts from Zostera marina may have value as the potential anti-inflammatory medicinal plant. Also based on the abovementioned results, ZM extract protects skin cells from UV-induced damages, and thus can be used in topically applied products for skin protection.
