简介:摘要建立了西藏八角莲不同组织鬼臼毒素的高效液相色谱分析方法,并以此对西藏八角莲不同部位中鬼臼毒素含量进行检测。结果显示色谱条件为,色谱柱whatesC18柱(125mm×4.6mm,i.d5μm),流动相甲醇∶水(55∶45),流速1.0ml·min-1,检测波长290nm,柱温25℃,进样量20μl。线性范围为20~200μg·ml-1,回归方程y=15121x-46585,r=0.9991,方法分离效果好,精密度高,RSD=0.835%(n=3)。对西藏八角莲根、块茎、叶、叶柄、花和果实中鬼臼毒素测定,六种组织中均检测到鬼臼毒素,但是不同组织含量差异较大,块茎中鬼臼毒素含量最高,180.50±2.74μg·g-1(干重),依次为根中,含量为58.83±1.59μg·g-1(干重),花中含量为40.33±1.24μg·g-1(干重),叶中含量为36.93±1.09μg·g-1(干重),叶柄中含量为29.90±0.45μg·g-1(干重),以果实中含量最低,为6.03±0.12μg·g-1(干重)。

简介:目的:由于狭叶茴香属于我国的濒危野生物种之一,寻找狭叶茴香的理想替代药材非常必要。本研究的目的是比较狭叶茴香和假地枫皮这两种八角属植物的根皮提取物注射液的抗炎镇痛作用。方法:本实验采用大鼠角叉菜胶足跖肿胀模型,小鼠耳廓二甲苯致炎模型以及醋酸引起的小鼠腹腔毛细血管通透性模型评价这两种注射液的抗炎活性。小鼠热板致痛模型和小鼠醋酸致痛模型评价这两种注射液的镇痛活性。结果:这两种注射液均表现出显著的抗炎镇痛作用。实验结果中没有出现显著性差异。结论:假地枫皮的根皮提取物注射液的抗炎镇痛作用与狭叶茴香的相当。实验结果显示,假地枫皮有可能成为狭叶茴香的理想替代药材。
