Comparative Studies on a Standardized Subfraction of Red Onion Peel Ethanolic Extract (Plant Substance), Quercetin (Pure Compound), and Their Cell Mechanism and Metabolism on MDA-MB-231

Figure 2

Dose-response curves of MDA-MB-231 following treatments with F1 for (a) 24 h, (b) 48 h, and (c) 72 h and with quercetin for (d) 24 h, (e) 48 h, and (f) 72 h. The maximal response (inhibition rate at the maximum dose concentration) identified hillslope value (slope at EC50 value) and an EC50 value of each test compound from the curve. The experiments were repeated several times to ensure the repeatability and reproducibility of the results. All values are expressed as the means ± SD.
