摘要
目的 研究夏枯草提取物对血管收缩的影响。方法 运用去甲肾上腺素引起家兔胸主动脉收缩模型的方法,记录了4种夏枯草提取物对去甲肾上腺素引起的家兔离体胸主动脉收缩曲线的影响。结果 夏枯草氯仿提取物、正丁醇提取物和乙酸乙酯提取物使去甲肾上腺素引起的家兔胸主动脉收缩曲线右移,且使其最大收缩幅度变小,而夏枯草水提取物则对去甲肾上腺素引起的家兔胸主动脉收缩曲线无明显的左移或右移。结论 夏枯草具有舒张血管、降低血压的作用。
Objective To investigate the effect of Prunellu vulgaris L.extracts on isolated rabbit artery. Methods The effect of Prunellu vulgaris L.extracts on the contraction curve caused by norepinephrine (NE) was recorded on isolated rabbit artery. Results The contraction curve moved to the right and the maximum contraction range was decreased by chloroform extract, butanol extract and ethyl acetate extract; the contraction curve had no move by aquatic extract. Conclusion Prunellu vulgaris L. has the effect of dilating artery and reducing blood pressure.
