The result of TLC shows that the three plants of Ajuga contain analogical chemical composition. three plants all contain luteolin.A. decumbens and A.nipponensis all contain esdysterone exclude A.dictyocar. But the latter contained higher amount than the former. TLC of A.dictyocar shows more differences. Thin-layer chromatography can sever as evidence to identificate them.

The experimental result shows quite well similar with oil sample chromatogram fingerprint from same reservoir at different commingle producing tracts F483 and Zhou182. But oil samples from different reservoir, its chromatogram fingerprint shows obvious different. This result can be used to monitor single-layer's output contribution.

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.

Through taken the measurements of pH, TOC, UV-Vis spectra and high-performance liquid chromatograph in the degrading process of solution ,it was found that the COD of dye solution increased, pH continuing declined and TOC reduced gradually. The UV-Vis spectra and high-performance shown that though dye molecules had been destroyed, Strong Chromophore Azo Double Bond of dye was certainly under attack, the big conjugated system was vandalized and dye molecules were decolorized degradation, but they were not completely changed into carbon dioxide and other inorganic matter by mineralization, it appeared accumulation of aromatic ring and double benzene nucleus, so it is thus evident that complete destruction of aromatic ring is more difficult than the double benzene.

通过测定直接大红染料脱色过程中的溶液pH、TOC、紫外可见光谱图和高效液相色谱图可知，在脱色处理时间(6h)范围内，染料溶液的COD值增大， pH值持续下降，TOC值逐渐降低，结合紫外可见光谱图和高效液相色谱图，说明染料分子虽然已经遭到破坏，染料分子内强生色基团偶氮双键确实遭到攻击，大的共轭体系被破坏，染料分子被脱色，却没有完全被彻底矿化成二氧化碳等无机物，出现了芳环和萘环结构的累积现象，可见完全破坏芳环比破坏偶氮双键发色团更困难。
