Abstract
Many studies have been carried out on bioactivities of individual herbs/fruits using in cosmetics or as a diet products, however, no collective study on their comparative antioxidant activities against oxidative damage or on cytotoxicity effect has been reported. The aim of this work was study the cytotoxicity and antioxidative activity of eight extracts with hypothetical antioxidative influence in vitro. To further elucidate of a possible role of herbals/fruits extracts on cell protection was used on the healthy and UV-A damaged mouse fibroblast cells. The cell viability was detect using MTT assay. Kinetic production of reactive oxygen species, identification of cell death, cell cycle and gene expression C-FOS were measured. Intracellular and mitochondrial transmembrane potential was evaluate with JC-1 fluorescence probe. Comet assay was employed to detect the UV-A induced DNA damage. The results indicated that using the extracts decreased ROS production. It can lead to greatly enhance and promote the viability of cells. As the most effective antioxidant in quenching of the ROS, in cell viability and DNA presentation was determined Prunella Vulgaris. However, one of them (Wheat Germ Oil) caused increased production of ROS and low cell viability.
