摘要
吴茱萸汤是治疗虚寒性偏头痛的经典方剂,其与偏头痛治疗相关的有效成分尚不明确。该实验采用大鼠外翻肠囊模型获取10种吴茱萸汤的吸收样品,以HPLC-DAD对吴茱萸汤及外翻肠囊吸收样品中9种成分进行定量、半定量,得到各成分在汤中的含量及在肠囊中的累积吸收量。同时建立利血平化小鼠偏头痛动物模型,在给予吴茱萸汤治疗后测定脑组织内5-羟色胺(5-hydroxytryptamine,5-HT),去甲肾上腺素(noradrenaline,NE),多巴胺(dopamine,DA)及脑组织与血清内一氧化氮(nitric oxide,NO)及其合成酶(nitricoxide synthase,NOS)的含量与活力。最后运用偏最小二乘回归法(partial least squares regression,PLSR)对各成分总吸收量与药效指标进行相关分析,发现了外翻肠囊吸收成分中影响药效的主要成分是柠檬黄素-3-O-β-D-葡萄糖苷(limocitrin-3-O-β-D-glucoside,Lcs),人参皂苷Rg1(ginsenoside Rg1,Rg1),人参皂苷Rb1(ginsenoside Rb1,Rb1)、吴茱萸苦素(rutaevine,Rv)、柠檬苦素(limonin,Li)、吴茱萸碱(evodiamine,Ev)及吴茱萸次碱(rutaecarpine,Ru),其中Rg1,Rv,Ev及Ru对多数药效指标具有正向改善作用,可能是影响吴茱萸汤治疗偏头痛作用的主要成分。
Wuzhuyu Tang is a classical formula for treating migraine, but its＇ pharmacological ingredients is unclear yet. Present study employed the everted intestinal sac model to collect the absorption samples of 10 kinds of Wuzhuyu decoction, and then analyzed the contents of 9 ingredients in Wuzhuyu Tang and absorption samples quantitatively or semi-quantitatively by HPLC-DAD method. Reserpine was used to establish the mice model of migraine, and then the contents and activities of 5-hydroxytryptamine, noradrenaline, dopamine, nitric oxide and nitricoxide synthase in brain tissues and serums were determined respectively after oral administration of Wuzhuyu Tang. Using the partial least squares regression method to correlate the total absorption quantity of 9 ingredients and pharmacodynamics. The result shows that limocitrin-3-O-β-D-glucoside, ginsenoside Rg1 and Rb1, rutaevine, limonin, evodiamine and rutaecarpine are the main ingredients influenced the effects in absorption samples in everted intestinal sacs, especially ginsenoside Rg1 , rutaevine, evodiamine and rutaecarpine among them have obvious improving effects to most pharmacodynamics index, might be the pharmacological ingredients influenced the therapeutical effects of Wuzhuyu Tang treating migraine.
