Activity of silibinin against methylglyoxal-induced glycation, revealed by the immunostaining of CML. Immunostaining of CML in untreated batch (A), treated with AG (B), treated with SMFE (C), treated with MG (D), treated with MG + AG (E) and treated with MG + SMFE (F). (G) Staining intensity on batches treated with active ingredients on CML immunostaining. The average staining intensity values were calculated using Image J software. Data are mean ± standard deviation. §
