Fig. 3. Effects of test compounds (from Clutia lanceoleta) on the glucose-triggered secretion of insulin from murine islets. Islets were incubated for 1 h at 37 °C in KRB buffer containing glucose (16.7 mM) in the absence (Control) or presence of test compounds and the secreted insulin was measured. Values are mean ± SD from three independent experiments. *P <0.05, **P <0.01, ***P <0.001 compared with the control value.
