Ethnopharmacological importanceGuazuma ulmifolia Lam (Sterculiaceae) is a plant extensively used in México for the empirical treatment of type 2 diabetes.Aim of the studyTo investigate the anti-diabetic mechanisms of Guazuma ulmifolia.Materials and methodsNon-toxic concentrations of Guazuma ulmifolia aqueous extracts (GAE) were assayed on adipogenesis and 2-NBDglucose uptake in the murine 3T3-F442A preadipose cell line.ResultsGAE added to adipogenic medium (AM) did not affect adipogenesis at any of the tested concentrations (1–70 μg/ml), whereas in AM lacking insulin GAE 70 μg/ml induced triglyceride accumulation by 23%. On the other hand, GAE 70 μg/ml stimulated 2-NBDG uptake by 40% in insulin-sensitive 3T3-F442A adipocytes and by 24% in insulin-resistant adipocytes, with respect to the incorporation showed by insulin-sensitive adipocytes stimulated with the hormone.ConclusionGuazuma ulmifolia exerts its anti-diabetic effects by stimulating glucose uptake in both insulin-sensitive and insulin-resistant adipocytes without inducing adipogenesis.
