GE, ear of C. ambrosioides L. collected from Guangxi, China; EE, ethanol extracts; K-3,7-D, kaempferol-3,7-dirhamnoside. Pearson correlation coefficients (PCCs) were calculated for strain BWSA11 exposed to quercetin (0.49 to 15.63 μg/mL), GE-EE (0.98 to 500 μg/mL), K-3,7-D (0.49 to 500 μg/mL), and rutin (1.95 to 500 μg/mL). **, significant at the level of 0.01 (2-tailed); *, significant at the level of 0.05 (2-tailed).
