Six new flavonoids, involvenflavones A-F (1-6), were isolated from Selaginella involven. Their structures were elucidated based on UV, IR, 1D and 2D NMR as well as HR-ESI-MS techniques. All compounds belong to apigenin derivatives with 3'-aryl substituent This is the first report of the apigenin derivatives with 3'-aryl substituent from nature resources. These compounds also exhibited a potent effect against the injury of human umbilical vein endothelial cell (HUVECs) induced by high concentrations of glucose in vitro. (C) 2015 Elsevier B.V.
