摘    要:目的:分离制备毛冬青三萜类化合物ilexgeninA,并初步探讨其药理活性,为阐明毛冬青的活性成分提供实验依据。方法:综合运用柱层析和重结晶法等分离纯化方法进行化合物的制备,采用^1H和^13CNMR波谱分析的方法对化合物的结构进行鉴定;小鼠口服给予不同剂量的ilexgeninA,通过考察其对凝血时间、出血时间、小鼠耳廓微循环血流速度的影响评价其药理活性。结果:ⅡexgeninA各剂量组与对照组相比,对小鼠出血时间和凝血时间均无明显影响(P〉0.05);ⅡexgeninA中、高剂量(50、100mg·kg^-1)组对小鼠耳廓微循环无明显影响,但低剂量组(25mg·kg^-1)可显著加快小鼠耳廓微循环血流速度(P〈0.05)。结论:小鼠口服给药后,ilexgeninA未显示出明显抗凝效果,但能促进小鼠耳廓毛细血管开放,改善微循环,其机制尚需进一步研究。

Abstract:Objective:To prepare triterpenoid ilexgenin A from the roots of Ilex Pubescens and investigate its pharmacological activities. Method;Ilexgenin A was separated and purified by the methods of column chromatography and recrystallization,and was identified by ~1H and ~(13)C NMR.After oral administration,the pharmacological effects of ilexgenin A were evaluated by clotting time(CT), bleeding time(BT)and blood flow rate of auricle microcirculation in mice.Result:Compared with placebo group,ilexgenin A showed no ...
Keywords:Ilexgenin A
