Capacitance variation in DOPS:DOPE:POPC PLM. Mean values of the membrane capacitance calculated as follows: just after the addition of each tested flavonoid (Ci ± SE); when the capacitance reached a minimum value (Cm ± SE); and when the capacitance reached a stable value (Cs ± SE). The time between the capacitance value immediately after adding the four flavonoids (Ci) and the minimum capacitance value (Cm) is shown in the fifth column (Time). The mean value was obtained from at least four experiments.
