(A) Levels of rosmarinic acid (RA) present in rosemary extract (RE). High-performance liquid chromatography (HPLC) chromatograph representing RE (upper panel) and RA standard (lower panel). (B) Effects of rosmarinic acid (RA) on glucose uptake (dose response). Serum-deprived L6 myotubes were incubated without or with 0.1, 0.5, 2, 5 or 10 μM RA for 4 h. 2-deoxy-d-glucose uptake was measured according to the methods. Data are expressed as percentage of control. Results are the mean ± SE of 3–4 independent experiments. ** p < 0.01, *** p < 0.001, vs. control.
