目的：从滋养细胞侵入、胎盘蜕膜血管网络形成、妊娠免疫监视／耐受机制、滋养细胞凋亡等角度，研究探讨黄芪、丹参复方成分提高胎盘血供的分子机制；方法：分离提取黄芪，丹参有效组分（黄芪总皂甙、总黄酮；丹参提取丹参酮、丹参醌、丹参酸三部分）。

It also revealed the antagonistic effect on myocardial hypertrophy pronouncedly in total timosaponins and total astragalus saponins treated group. Conclusions Total timosaponins has the restrain effect on myocardial hypertrophy induced by isoprenaline in mouse. Among the selected doses, the theoretical optimal proportion of total timosaponins and total astragalus saponins is (25+100) mgkg^(-1). The complex prescription can enhance the action.

黄芪总皂苷对盐酸异丙肾上腺素所致小鼠心肌肥厚具有显著的抑制作用；知母总皂苷与黄芪总皂苷在所选择剂量范围内的理论最佳配比为(25+100)mgkg^(-1)；知母总皂苷与黄芪总皂苷组成的复方有抗盐酸异丙肾上腺素所致小鼠心力衰竭作用。

Objective To establish the chromatographic fingerprint analysis for the quality control of Radix Astragali.

3 The effects of APS and AstragalosideⅣon synthesis of collagen Measure the Radix Astragali impact on NIH3T3 cells collagenic synthesis of many candies with the hydroxyproline reagent box.

2.3黄芪多糖和黄芪甲苷对胶原合成的影响本实验以NIH3T3为细胞模型，用羟脯氨酸试剂盒测量黄芪多糖对NIH3T3细胞胶原合成作用的影响。

The results showed that the D50 of Astragalus membranaceus and Epimedium brevicornum ultra-fine powder were 6.82μm and 8.40μm separately. The broken cellular walls of two ultra-fine herbal powder were bigger than those of the commonly cribble, and intact cells were not visible under SEM, and it improved the mixed uniformity. On the contrary, organization blocks of the commonly cribble were clearly discernible, also the shape and granularity were irregular, and the organization cells were still complete. The bulk density and liquidity of Astragalus membranaceus and Epimedium brevicornum increased significantly after ultra-fine Smashing. The component icariin extraction content of the ultra-fine powder was enhanced by 18.31% compared with the cribble by the chromatograph analysis of icariin. At the same time, Astragalus membranaceus polysaccharide and Epimedium brevicornum polysaccharide content of the ultra-fine powder were enhanced by 117.13% and 315.15% compared with the cribble.

结果发现黄芪和淫羊藿经超微粉碎后，粉体的粒度分布中心D_(50)分别为6.82μm和8.40μm，经电镜观察均难以看到完整的细胞形态，只能看到细胞碎片，破壁率远远大于普通粗粉，其混合的均匀度显著提高，而普通粗粉在显微镜下，组织块清晰可见，且形状不规则，粒径分布不均匀，组织细胞仍然完整；超微粉碎后，黄芪和淫羊藿的堆密度和流动性显著增强；通过对淫羊藿有效成分淫羊藿苷的色谱分析，其中淫羊藿超微粉的淫羊藿苷体外溶出量较淫羊藿粗粉中提高了18.31%；同时黄芪、淫羊藿超微粉多糖的提取率分别较黄芪、淫羊藿粗粉提高了117.13%，315.15%。

In addition, a pre-column derivatization HPLC method was applied to the determination of Astragaloside Ⅳ; the flavonoids was determined by full-range HPLC scanning; a colorimetric method was developed for the determination of flavonoids and saponins. Hierarchical cluster analysis was performed on three constituents of different Radix Astragali species, and its result was compared with those of traditional phytoecological identification and the pharmacological quality assessment.

本研究以比色法测定了黄芪中总皂苷的含量，以柱前衍生化高效液相色谱法测定了黄芪中黄芪甲苷的含量；以比色法测定了黄芪中总黄酮成分的含量，以反相高效液相色谱法测定了黄芪中毛蕊异黄酮和毛蕊异黄酮苷的含量；以黄芪中的黄芪甲苷、毛蕊异黄酮和毛蕊异黄酮苷为主要特征对不同品种的黄芪进行了系统聚类分析，并将聚类结果与传统生药学鉴定和药理质量评价结果进行了比较。
