Previous studies have revealed the medicinal and therapeutic effects of . However, no studies have focused on the antihypertensive effects of . Therefore, we aimed to determine the vasorelaxant and hypotensive effects of 50% ethanolic extract (GCE). To evaluate the vascular relaxing effect of GCE, experiments were conducted using aortic segments dissected from Sprague Dawley rats. GCE showed a vasorelaxant effect via the nitric oxide/cyclic guanosine 3',5'-monophosphate pathway, inhibiting Ca channels, and activating K channels. The hypotensive effects of GCE were evaluated in spontaneously hypertensive rats (SHRs). The SHRs were randomly divided into a control group and orally administered GCE group (100 or 300 mg/kg). The systolic and diastolic blood pressure decreased significantly by -19.47 ± 4.58% and -31.14 ± 7.66% in the GCE 100 mg/kg group, and -21.64 ± 2.40% and -31.91 ± 5.75% in the GCE 300 mg/kg group at 4 h after administration. Considering its vasorelaxant and hypotensive effects, our results indicate that GCE may be a valuable solution for the control of hypertension. However, further studies on the long-term administration and toxicity of GCE are required.
先前的研究已经揭示了 的药用和治疗功效。然而,目前还没有研究集中于 的降压作用。因此,我们旨在确定 50%乙醇提取物(GCE)的血管舒张和降压作用。为了评估 GCE 的血管舒张作用,使用从 Sprague Dawley 大鼠分离的主动脉段进行了实验。GCE 通过一氧化氮/环鸟苷酸 3',5'-单磷酸途径、抑制钙通道和激活钾通道表现出血管舒张作用。在自发性高血压大鼠(SHR)中评估了 GCE 的降压作用。SHR 被随机分为对照组和口服 GCE 组(100 或 300 mg/kg)。GCE 100 mg/kg 组的收缩压和舒张压分别显著下降了-19.47±4.58%和-31.14±7.66%,GCE 300 mg/kg 组分别下降了-21.64±2.40%和-31.91±5.75%,在给药后 4 小时。考虑到其血管舒张和降压作用,我们的结果表明 GCE 可能是控制高血压的一种有价值的方法。然而,需要进一步研究 GCE 的长期给药和毒性。
