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。

Bamboo first crystallizes then lignifies during bamboo shoot growth and basically forms crystal structure in one month. 1-year-old bamboo culm ends growth and its height,thickness, volume almost change little, but culm tissue is small and tender and there is more water and less substance in it. Bamboo crystal proportion keeps invariable during this period.2-year-old bamboo culm begin to lignify,its cellulose proportion debases and its crystal proportion decreases. Bamboo lignin debases, crystal proportion changes a little in the end of this period.Many-old-year bamboo culm crystal proportion is almost invariable. Freaky bamboo cell wall crystal region's thickness is less than normal bamboo's. Bamboo cross section crystal area and the ratio of long axis to short axis are less than normal bamboo's,and roundness,irregular index, the fiber cap density per unit area increase more than normal bamboo's.

竹笋生长阶段是先结晶后木素化的过程，一个月内细胞壁结晶组织基本形成；2）一年生竹材的植株秆茎生长结束，秆茎的高度、粗度和体积变化不大，但秆茎的组织幼嫩，含水量高，干物质少，竹材结晶度基本不变；3）二年生竹材的植株开始木质化，纤维素比例降低，结晶度减少，到后期竹子木质化降低，竹材结晶度变化不大；4）多年生竹材的结晶度没有太大的变化，结晶度大小处于波动状态；5）畸形竹材纤维帽细胞壁结晶区的厚度比正常竹小，其横截面结晶区的面积、纤维帽长轴与短轴比有所减少，而圆形度、异型指数有所加大，单位面积纤维帽的密度增大。

The results were summarized as follows:① The length and dried weight of shoot and the differentiation of leaves were enhanced on a culture medium with α-Naphthaleneacetic acid, and the effectiveness of NAA became stronger with the incerase in concentration within a range of 0.001 mg/L to 0.1 mg/L.

结果表明：①萘乙酸促进银杏茎尖伸长生长和叶片分化，随NAA浓度增加其作用增强，在NAA为0.1 mg/L时茎尖长度为对照的1.47倍，分化叶数为对照的2.62倍，茎尖干重为对照的6.45倍。
