Quercetin, quercetin rhamnoside, hyperin, syringoside and eleutheroside E wereisolated from the flower of Acanthopanax senticosus. Searching bioactive natural compound and establishing quality evaluation standard arefocused on this experiment. Using cold immersing of 70% methanol to extract from flower ofAcanthopanax senticosus and integrating macroporous resin, silica gel column chromatography,sephadex gel to abstract. We obtained five monomer compounds (compoundⅠ-compoundⅤ),quercetin, quercetin rhamnoside, hyperin, syringoside and eleutheroside E. That five compoundswere determined by HPLC in eight parts of Acanthopanax senticosus (flower, root, leaf fruit,shoot, new shoot, phloem of shoot, skin of shoot), which provide science bases for establishingquality evaluation system and settle infarctate foundation.

本文以从刺五加花蕾中寻找具有重要生物活性的天然化合物和建立质量评价标准为主要目的，对其化学成分进行研究，采用70％甲醇冷浸的方法对刺五加花蕾中的成分进行提取，运用大孔树脂吸附色谱法、硅胶柱层析法以及葡聚糖凝胶柱层析相结合的方法进行分离，得到5种单体化合物，分别为槲皮素、槲皮素鼠李糖苷、金丝桃苷、紫丁香苷和刺五加苷E；利用高效液相色谱法对这5种化合物在刺五加花蕾中的含量进行了测定；考察了8个部位(花蕾、根、叶、果、茎干、新枝、茎韧皮部、茎皮)中这5种化合物的含量分布情况，并作一比较，为今后建立刺五加质量评价体系提供了科学依据，奠定了坚实的基础。
