植物多酚紫铆花素(3,4,2’,4’-四羟查耳酮)为漆树(Rhusverniciflua)的主要活性成分之一,具有抗氧化、抗炎、内皮依赖性舒张血管、诱导凋亡、抑制蛋白激酶和谷胱甘肽还原酶活性、抗HIV-1蛋白酶和治疗肾小球肾炎等作用。本次通过检测其体内、外抑制血管紧张肽转化酶(ACE)活性,以阐 The plant polyphenols bindweed (3,4,2’,4’-tetrahydroxychalcone) is one of the main active components of Rhus verniciflua and has antioxidant, anti-inflammatory, endothelium-dependent vasodilation and induction. Apoptosis, inhibition of protein kinase and glutathione reductase activity, anti-HIV-1 protease and treatment of glomerulonephritis and other effects. In this study, we examined the inhibition of angiotensin-converting enzyme (ACE) activity in vitro and in vivo.
