Dose-dependent effects of Afrostyrax lepidophyllus (a) and Monodora myristica (b) extracts on H9c2 cell mass measured by the SRB assay. Cell treatment was performed as described in Section 2.5. The results represent mean ± SD of six biological replicates. ^∗∗∗∗p < 0.001 vs. control (no Dox added), ⁺p < 0.05 vs. Dox only; ⁺⁺p < 0.01 vs. Dox (untreated cells treated with Dox). Dox: doxorubicin. Afro: Afrostyrax lepidophyllus water/ethanol extract. Mono: Monodora myristica water/ethanol extract. Vehicle: H₂O/ethanol (30/70).
