abstract：:Arbutin, a glycoside extracted from the plant Arctostaphylos uva-ursi, has been previously reported to possess antioxidant, anti-inflammatory and anticancer effects. Here, we investigated whether arbutin affects the proliferation of the cells of the osteosarcoma (OS) cell lines MG-63 and SW1353. Arbutin suppressed OS ...
