The percentage of cell viability by MTT exclusion on Mouth epidermoid carcinoma cell (KB) cells (a), skin squamous cell carcinoma (A431) cells (b) and fibroblast cell lines (c). Data are expressed as mean ± SD (n = 3). ***p < 0.001 and ** p < 0.01 indicated in compare between samples. # There was no significant difference between control with Q 50 μg/ml and Q 25 μg/ml in KB, 50 μg/ml and 25 μg/ml of AEEP and Q in A431 and the all concentrations of AEEP and Q in fibroblast cell lines (p < 0.05)
