最近研究已表明贯叶金丝桃(Hypericum perforatum L.)提取物中的原矢车菊甙元(PC)部位对血管有活性,其中含PC寡聚物的部位对离体猪冠状动脉的作用最强。另外,已知蔷薇科山楂属(Cratacgus)植物提取物中的含PC部位能提高离体豚鼠心脏的冠脉流量。木文研究贯叶金丝桃中寡聚物PC在1×10~(-8)～5×10~(-6)g/ml浓度范围内对离体豚鼠心脏博动及冠脉流量的影响。结果表明:1.房前收缩力:在低浓度时(1×10~(-8)～1×10~(-6)g/ml时)没有影
Recent studies have shown that the original cyanidin (PC) site in Hypericum perforatum L. extract is active against blood vessels, and the site containing PC oligomers has the strongest effect on isolated porcine coronary arteries. . In addition, it is known that the PC-containing site in the extract of the plant of the genus Crataccus can increase coronary flow in an isolated guinea pig heart. The study of the effects of oligo-PC in Hypericum perforatum on cardiac pulsation and coronary artery flow in isolated guinea pigs at a concentration range of 1×10~(-8) to 5×10~(-6) g/ml. The results showed that: 1. Preatrial contraction: no effect at low concentration (1×10~(-8)～1×10~(-6)g/ml)
