Percentage (mean ± SD, n = 3) cell viability (MTT assay) in NIH-3T3 (murine skin fibroblasts), NCI-H460 (human lung carcinoma cells), and MCF7 (human breast adenocarcinoma) cells, treated with whole apple (Malus domestica cv. Anna) extract (1 mg ml−1) for 24 h. A. NIH-3T3 (0, 61, 77, 92, 107, 123 μg GAE ml−1). B. NCI-H460 (0, 46, 65, 84, 102, 123 μg GAE ml−1). (C) MCF7 (0, 15, 31, 46, 61, 77 μg GAE ml−1). Statistical differences relative to the untreated controls were determined by one-way ANOVA followed by a Dunnett´s post-test (*p < 0.05) (Graph-Pad Prism v. 8.01)
