Based on the previous literatures, the following major innovation works were carried out in this dissertation:(1) The derivatization reaction conditions of ephedrine and pseudoephedrine with sensitive derivation reagent in aqueous system were studied and two new methods were developed for the assay of them by microemulsion electrokinetic chromatography and micellar electrokinetic chromatography with LIF detection. The sensitivity and analysis times were greatly improved compared with the previous reports;(2) A new method of CZE with indirect LIF detection was developed for the simultaneous determination of six coumarin compounds (esculin, esculetin, isofraxidin, genistein, naringin and sophoricoside) with fluorescein as the probe. The proposed method enlarges the application range of LIF detector, and provides new approach for the analysis of certain compounds difficult to derivatize;(3) Based on the above research, an MEKC with indirect LIF detection method for the simultaneous determination of adenine and guanine in DNA extracts from fungus, maize and soybean was established;(4) A new method for the investigation of the complexes formed between human serum albumin and ampicillin sodium under the simulated physiology conditions using laser light scattering technique was developed.

该论文在综述前人工作的基础上，开展了如下未见文献报道的创新性的研究工作：(1)使用灵敏的衍生试剂对麻黄碱和伪麻黄碱在水体系中的衍生反应条件进行了系统研究，建立了微乳电动色谱-激光诱导荧光检测法和胶束电动色谱—激光诱导荧光检测法测定麻黄碱和伪麻黄碱的灵敏分析新方法，与以前的报道相比，灵敏度和分析时间均有很大改善；(2)使用荧光素钠作为背景荧光试剂，建立了同时分析测定六种黄酮类化合物(秦皮甲素、秦皮乙素、异秦皮定、染料木素、柚皮苷和槐角苷)的毛细管区带电泳—间接激光诱导荧光检测新方法，扩大了激光诱导荧光检测的应用范围，对难衍生化合物的分离分析提供了一种新思路和新途径；(3)以荧光素钠作为背景荧光试剂，建立了一种用于同时测定食品提取DNA中的腺嘌呤和鸟嘌呤含量的胶束电动色谱—间接激光诱导荧光检测新方法；(4)用动态和静态激光散射法研究了模拟生理条件下人血清白蛋白与氨比西林钠盐相互作用所形成的复合物，为药物分子与蛋白质的相互作用、药代动力学等的研究提供了一种新思路。

Results:LIF improved the development rate of early embryo at the concentration of 0.1,1 and 10ng/ml(P.05).The enhanced effects of LIF were significant for morula and blastocyst stage,not for 1～8 cell stage of embryos.Conclusion:LIF may improve the development of early mouse embryos at the appropriate concentration.

结果：①0.1ng/ml、1ng/ml和10ng/ml浓度的LIF对小鼠早期胚胎的发育和胚泡的形成有促进作用，0.01ng/ml和100ng/ml浓度的LIF对胚胎的发育无明显影响；②LIF对小鼠早期胚胎发育的影响主要发生于桑椹胚和胚泡期，对1～8细胞期胚胎无明显影响。

Non-fluoride ionic number of Nd-F in dilute LiF-NdF3 melts and Nd-O-F species in dilute LiF-NdF3-Li2CO3 melts was researched by cryoscopic method,respectively.

采用冰点降低法分别研究了以LiF为溶剂的稀LiF-NdF3熔盐中Nd-F离子团及LiF-NdF3-Li2CO3熔盐中Nd-O-F离子团的非氟离子的个数。
