Abstract

The aim of this study was to evaluate the role of glucose transporter-4 (GLUT4) in the anti-diabetic effects of methanol, hexane and dichloromethane extracts of the aerial parts of Ocimum basilicum (OB) and to analyze their phytochemical composition. Phytochemical analysis of the three extracts by GC/MS using the silylation derivatization technique revealed 53 compounds, 17 of them were found for the first time in OB. Cytotoxic and anti-diabetic properties of the extracts were evaluated using L6-GLUT4myc muscle cells stably expressing myc epitope at the exofacial loop (GLUT4). No cytotoxic effects were observed in treated cells up to 0.25 mg/ml extract as measured with MTT and LDH-leakage assays. GLUT4 translocation to the plasma membrane was elevated by 3.5 and 7 folds (-/+ insulin) after treatment with OB extracts for 20 h. Our findings suggest that the observed anti-diabetic properties of OB extracts are possibly mediated in part through one or more of the 17 new identified compound.
