Boropinic acid, 4-geranyloxyferulic acid, 7-isopentenyloxycoumarin, auraptene (0.1, 1, 10 μM), and raw Italian propolis (0.001–1 mg/mL)  In vitroDifferentiated L6 myoblast cells isolated from rats  EGs: boropinic acid, 4-geranyloxyferulic acid, 7-isopentenyloxycoumarin, auraptene (0.1, 1, 10 μM), and propolis (0.001–1 mg/mL)CG1: insulin (0.1 μM)CG2: DMSO  GLUT4-mediated glucose uptake and GLUT4 translocation.  Propolis (1.0 and 1 mg/mL), 4-geranyloxyferulic acid, 7-isopentenyloxycoumarin, and auraptene significantly increased glucose uptake and GLUT4 translocation.  [69]
