a A. millefolium (Am), H. matronalis (Hm), H. pilosella (Hp), I. pandurata (Ip), R. multiflora (Rm), S. virginica (Sv), S. canadensis (Sc); Flower (FL), Leaf (LV), Stem (ST).
-
b Unstandardized regression coefficient and standard error. ** indicates P < 0.01; *** indicates P < 0.001. There were three replicates for each dilution series.
-
c MIC (mg/mL) observed in serial dilution assay.
-
d MIC (mg/mL) calculated utilizing 95% confidence limit of regression slope to conservatively predict the concentration at which the proportion of bacteria killed goes to zero.
-
e Because the observed proportion of bacteria killed went to zero by the 6.25% dilution (6.25 mg/mL), the regression statistics were calculated using only the first four points of the dilution series.
