Protective Effect of Mangifera indica Linn., Cocos nucifera Linn., and Averrhoa carambola Linn. Extracts against Ultraviolet B-Induced Damage in Human Keratinocytes

Figure 1

The effect of M. indica, C. nucifera, and A. carambola extracts on viability of HaCaT cells. Detection of cell viability was performed using MTT assay. HaCaT cells were treated with Thai fruit extracts at the concentration of 0–500 µg/mL for 48 h. The aqueous extract of A. carambola could significantly decrease cell viability. The aqueous extract of A. carambola at the concentration of 500 µg/mL could significantly decrease cell viability in comparison with the cell viability of untreated group.
