| Abstract: | The effect of n butanol extract of Atractylodes japonica Koidz.ex Kitam. on the contraction induced by norepinephrine or potassium chloride was studied on the rabbit aortic strips. The results showed that extract of Atractylodes japonica Koidz.ex Kitam.inhibited the contraction of aortic strips evoked by norepinephrine or potassium chloride,and could shift dose response curves for norepinephrine or potassium chloride to the right in a non parallel fasion and depress their maximal response showing noncompetitive antagonism. This suggests that extract of Atractylodes japonica Koidz.ex Kitam. has an effect on inhibiting action of poential dependent calcium channel and that of receptor operated calcium channel. |
