Table 2 Comparison of cancer cell viability treated with 1 mg/mL aril water extract after 24 h from Vietnam (Southern, Central and Northern), Thailand and Australia using CCK-8 assay. Fisher’s LSD values were generated from un-transformed cell viability data of MM418C1 (df = 14, F = 10.42, p = 0.000), D24 (df = 14, F = 15.58, p = 0.000) and MCF7 (df = 14, F = 2.22, p = 0.069) cell lines. The results were averages of three individual experiments which were performed in duplicate
