Figure 5

The inhibition of MMP-1 synthesis after treatment with various concentrations of three different extracts and 0.1% retinol as a positive control. GE, gel juice extracted after peeling off the leaves of A. vera; WE, the water extract from the whole aerial parts of A. arborescens at 100°C for 24 hours; FE, fermentation of the whole aerial parts of A. arborescens grown with L. plantarum at 37°C for 4 days and further extracted by an ultrasonicator at 40 kHz for 1 hour at room temperature. Error bars are mean values ± SD from triplicate separate experiments. The significance of difference was set to , , and compared with the control group.
