Effect the xanthones extracts on mitochondrial membrane potential and chromatin condensation. The mitochondrial membrane potential (a): negative control (1), α-mangostin at 20 μg/ml (2) and the xanthones extract at 20 μg/ml (3). Chromatin condensation (b): negative control (1), α-mangostin at 20 μg/ml (2) and the xanthones extract at 20 μg/ml (3).
