In this research, swainsonine contents of three Oxytropis species were determined by the high performance liquid chromatography coupled to mass spectrometry. The population genetic diversity was also studied and the swainsonine related molecular markers were screened by ISSR. In vitro fungi cultures from the individual plant of O. glabra were performed and microbiological morphology of the colony and the conidiophore were investigated. The 5.8S rDNA/ITS sequences of fungi amplified from total DNA in both plants and fungal endophytes were studied. These sequences were analysed and compared, and they were also compared to the 5.8S rDNA/ITS sequence of fungal enduphyte Embellisia sp. L12 from the O.lambertii, O.sericea and A.mollisimus distributed in USA.

本研究采用高效液相色谱-质谱联用法测定了三种棘豆植物的苦马豆素含量；通过ISSR分子标记技术对三种棘豆种群遗传多样性及其苦马豆素相关标记进行了研究；将小花棘豆植物单株进行体外真菌培养，研究了菌落和分生孢子的微生物形态学特性，从植物总DNA和相同植株培养的真菌总DNA扩增真菌的5.8SrDNA/ITS区，进行了DNA序列分析与排序；联系单株小花棘豆的苦马豆素含量测定和内生真菌ITS序列分析结果，与从美国分布的二种棘豆(O.lambertii、O.sericea)和一种黄芪(A.mollisimus)中分离的内生真菌埃里砖格孢属Embellisia sp.L12株得到的结果进行了比较。

First by introducing the sufficient decrease condition,the Wolfe condition and the Goldstein condition with their strong local search capabilities, do the step length selection. The search direction is using conjugate gradient direction.

通过引入经典优化中局部搜索能力较强的充分下降条件、Wolfe条件、Goldstein条件确定步长，而搜索方向采用共轭梯度方向进行局部搜索，由此得到一类高效的非精确的混合遗传算法。

To solve this problem, we consider that use of tissue-specific regulative elements in construction of plasmid vector for molecular conjugate vector may limit the expression of foreign gene to targeting cells further.

为解决这一问题，我们考虑在构建分子偶联载体中的重组质粒表达载体时，应用组织细胞特异性调控序列，以期在转录水平进一步限制外源基因的表达于靶细胞中，从而保证受体介导基因转移的靶向性，同时可望导致外源基因的高效表达。

MethodsAfter oral administration of Wuchai Particles(2 g/kg) for the mice , the serum was collected at different time points .The components in the Wuchai Particles and serum were analyzed by HPLC to monitor the changes of the schizandrin in serum so as to draw the curve of concentration connected with time .
