Fig. 4From: Anti-microbial and anti-cancer efficacy of acetone extract of Rosa chinensis against resistant strain and lung cancer cell lineMTT assay. A549 cells were treated with different concentrations of rose extract for 48 h. Control is concentration 0 µg/ml of RE. Cell viability assay was performed using MTT and measuring absorbance at 48 h. Data were represented as mean ± SEM, performed in triplicate. *p < 0.05 and **p < 0.01 for 0 µg/ml vs. 100, 250, 500, 750 and 1000 µg/ml. Data was analysed using one-way ANOVA followed by Dunnett’s multiple comparison t-test)Back to article page
