To investigate the diastolic function of quercetin on rat renal artery in vitro and its mechanism, the tension of rat renal artery was recorded by multi myograph system, and the L-type voltage-gated Ca~(2+) channels(LVGC) current was recorded by whole-cell patch clamp technique. Quercetin produced relaxation effect on rat renal artery pre-contracted by 60 mmol/L KCl or 1 × 10~(-5) mol/L phenylephrine, and the maximal diastolic percentage was(84.53 ± 7.35)% or(76.42 ± 4.63)%. There was no statistical differe...
