结果表明，对评吸结果影响较大的是胡萝卜素降解产物类和棕色化反应产物类；类西柏烷类和苯丙氨酸类中性致香物质的贡献较小；负面影响较大的成分主要集中在吲哚、甲苯及一些醛类上，类胡萝卜素降解产物类和棕色化反应产物类中的个别成分也有一定的负面影响。

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。

X-ray examination demonstrated that at 4 weeks after implantation, some or even lateral intertransverse bridging regions were unclear, and material density in the repairing group was lower than control group; at 8 weeks after implantation, interspace between up and down bridging was shrunk, and a great quantity of calluses were successively formed; at 12 weeks after implantation, complete confluence was observed, and the density in the repairing group was closed to that in the control group.

结果：采用脱蛋白处理后的松质骨可见大小不等、相互交通、开放孔隙的网架结构，孔径200~500 μm，孔隙率60%左右，其无机成分为羟基磷灰石，有机成分为胶原，力学性能保存良好，细胞相容性良好。X射线片结果显示：植入第4周，横突桥接处部分区域模糊，以内侧明显，此时修复组材料密度略低于对照组；第8周上下桥接部间隙变小，大量连续骨痂生成；12周后完全融合，两组材料密度接近。

Increase of that clast of sedimentary rock, high-grade metamorphic rock and unstable heavy minerals shows tectonically active setting and obvious uplift of Bogda Mountain during the Late Jur.

新疆博格达地区中—新生界碎屑成分自中侏罗世的中晚期开始发生了巨大变化，主要表现在：自中侏罗世晚期开始，沉积重矿物组合及相对含量发生较大变化，不稳定重矿物、较高级别变质岩岩屑明显增多，显示此时发生的物源属性变化及构造活动的存在；自侏罗系西山窑组沉积晚期开始，砂岩碎屑成分中的沉积岩碎屑明显增加，显示盆缘沉积岩物源的隆升和剥蚀作用。

Under normal circumstances, this is not a problem because food proteins contain only the major components of nitrogen and other major components are not nitrogen, the Kjeldahl method is a very accurate determination of protein content .

在通常情况下，这不是个问题，因为食物中的主要成分只有蛋白质含有氮，其他主要成分都不含氮，因此凯氏定氮法是一种很准确的测定蛋白质含量的方法。
