【摘 要】 目的:观察野蚕豆根中总环烯醚萜苷对非酒精性脂肪肝大鼠肝脏功能的影响。方法:采用高脂饲料喂养4周建立非酒精性脂肪肝大鼠模型,给药4周后,全自动生化仪检测大鼠血清生化,HE染色观察肝脏病理情况。结果:血清生化结果显示,总环烯醚萜苷可以降低非酒精性脂肪肝大鼠血清甘油三酯(TG)、低密度脂蛋白胆固醇(LDL-C)水平和丙氨酸氨基转移酶(ALT)活性,升高高密度脂蛋白胆固醇(HDL-C)水平。病理结果显示:总环烯醚萜苷组脂肪空泡较模型组变小变少。结论:动物实验表明野蚕豆根中的总环烯醚萜苷成分无肝毒性,且有一定保肝护肝、降脂作用。

Abstract:Objective To observe the effect of total iridoid glycosides in Centranthera grandiflora on liver function in non-alcoholic fatty liver rats. Methods The rats were fed with high-fat diet for 4 weeks to establish a non-alcoholic fatty liverrat model. After 4 weeks of administration, the automatic biochemical analyzer was used to detect the serum biochemistry of the rats, and HE staining was used to observe the liver pathology. Results Total iridoid glycosides reduced the levels of triglyceride (TG), low density lipoprotein cholesterol (LDL-C) and alanine aminotransferase (ALT) activity, and increased the level of high density lipoprotein cholesterol (HDL-C) in rats with nonalcoholic fatty liver disease.Pathological results showed that fatty vacuoles in total iridoid glycosides group were smaller and less than those in model group. Conclusion The total iridoid glycosides in Centranthera grandiflora had no hepatotoxicity, and had some hepatoprotective and lipid-lowering effects.

野蚕豆根,又名化血丹、小红药、金猫头(广西)、灵芝草(云南),原植物来源于玄参科(Scrophulariaceae) 胡麻草属(Centranthera) 植物大花胡麻草Centranthera grandiflora Benth,主要分布于云南、贵州、广西等地,越南、缅甸、印度也有分布[1]。野蚕豆根主要含有环烯醚萜苷类、苯乙醇苷类、类胡萝卜素类、紫罗兰酮苷类、单萜苷类等化合物[2],桃叶珊瑚苷是野蚕豆根中含量最高的环烯醚萜苷类成分[3]。

环烯醚萜苷广泛存在于自然界许多植物种属中,在车前科、玄参科、杜仲科、忍冬科等植物中均有发现,具有降糖、保肝、抗炎、抗凝血等作用,还可发挥DNA合成酶抑制剂的作用[1]。

野蚕豆根在其产地云南省红河州常被用于防治心脑血管疾病,收效甚好。其主要的化学成分为环烯醚萜苷,但有关野蚕豆根的药理作用研究却十分有限,关于其药理药效方面的研究甚少。……
