摘要 [目的]对藏药小大黄总提物、乙酸乙酯部位和水部位进行降尿酸活性的研究,确定其降尿酸有效部位。[方法]称取藏药小大黄干燥的根500.0 g,用70%乙醇提取浓缩,加入乙酸乙酯萃取,得乙酸乙酯部位和水部位,研究小大黄总提物、乙酸乙酯部位和水部位对高尿酸血症小鼠的血清尿酸(UA)、肝脏黄嘌呤氧化酶(XOD)、腺苷脱氨酶(ADA)、肌酐(Cre)以及血尿素氮(Bun)的影响。[结果]藏药小大黄总提物和水部位具有一定的降尿酸和抑制XOD、ADA、Cre以及Bun活性。[结论]水部位是藏药小大黄降尿酸有效部位,其降尿酸作用的机制之一是抑制 XOD 活性。

Abstract [Objective] The research aimed to study the effect of total extract of Rheum pumilum (TER), ethyl acetate extract, as well as water extract on the level of uric acid and define its active fraction.[Method]The root of the dried rhubarb was weighed 500.0 g, extracted with 70% ethanol, concentrated to a small amount of volume and extracted with ethyl acetate to obtain ethyl acetate and water.The level of uric acid (UA), xanthine oxidase (XOD), adenosine deaminase (ADA), creatinine (Cre) and blood usea nitrogen (Bun) on TER, ethyl acetate extract and water extract were analyzed.[Result]The TER and water extract had a certain effect on reducing the level of UA, XOD, ADA, Cre and Bun.[Conclusion]Water part of Rheum pumilum was the target area for antihyperuricemia, and the effect was related to its inhibition of XOD.

痛风属中医“痹症”“痛风”“白虎历节”的范畴,在藏医药中,多属“黄水病”范畴。痛风一病的发作,临床症状主要以关节红肿疼痛为主要表现,特别以下肢关节最为明显。关节红肿疼痛属藏医的“黄水病” 范畴。藏医理论认为,所有疾病的发生是“三大因素”(即“龙”“赤巴”“培根”)失调所致,“龙”“赤巴”“培根”的失调可导致黄水病的产生。“黄水”流著于骨,临床上可见关节肿胀等。“黄水病”“恶性腹水” 是藏区多发疾病,也是藏医学临床具有治疗优势的病种之一。“曲玛孜”类药材为常用治疗这类疾病的藏藥材。文献记载各地藏医所用的“曲玛孜”类药材的基原植物有一定差异,涉及到蓼科大黄属多种大黄和同科蓼属植物西伯利亚蓼根或全草,《藏药标准》 在“曲玛孜”条目下收载了蓼科植物小大黄(Rheum pumilum)和西伯利亚蓼(Polygonum sibiricum Laxm.),干燥全草入药[1]。……
