烷基取代磷酸及其烷基酯如P229、P507、P204等物质是溶剂萃取和萃取色谱法分离稀土元素的常用萃取剂。我们首次把次磷酸功能基因通过化学键合的方式链接到苯乙烯-二乙烯苯共聚树脂骨架上,合成了次膦酸功能树脂并应用于稀土元素的色谱分离。由于苯基是吸电子基,若直接与次膦酸基相连会使次膦酸基上氧原子的电子云密度下降,对配位反应不利;若在树脂的苯环与次膦酸基之间嵌入一

[Objectives] To establish a simple and rapid,specific and reproducible thin layer chromatography( TLC) method,and accordingly establish a thin layer identification method for quality control of Glycyrrhiza uralensis. [Methods] According to the physical and chemical properties,components of Glycyrrhiza uralensis were identified by thin layer chromatography. According to Veterinary Pharmacopoeia of the People's Republic of China 2010( Volume Ⅱ) and related literature report,the thin layer chromatography identification method was studied and improved for Glycyrrhiza uralensis.[Results] When the preparation method for test sample solution was 6g Glycyrrhiza uralensis added with 30 mL saturated n-butanol,ultrasonic processing 20 min,filtered,filtrate dried,added 3 mL methanol and obtained Glycyrrhiza uralensis test sample solution. Then,chloroform-methanol-formic acid-ethyl acetate( 10∶ 3∶ 2∶ 3) as developing solvent,clear spot with high degree of separation and reproducibility could be obtained,and can be used for thin layer chromatography identification of ammonium glycyrrhetate in Glycyrrhiza uralensis.[Conclusions] The modified method omitted the step of ether treatment of samples,and directly adopted saturated n-butanol to extract components. It does not influence the detection of chromatographic spots,and solves the issue of sample gelatinizing sticking and filtration,simplifies the test process,and reduces the harm to human body.

[Objective]The paper was to understand the resistance of commonly used clinical antibiotics to avian Escherichia coli and the inhibition of lactobacillus against pathogenic ***.[Method]The strain was isolated and identified by SS medium culture,microscope examination,PCR amplification and biochemical test,and the sensitivity of avian *** to eight antibiotics was determined by disk diffusion *** strains of avian *** and one strain of lactobacillus were divided into five group using in vitro liquid culture method,namely simultaneous mixed culture group of lactobacillus and ***,first colonization group of ***,first colonization group of lactobacillus,*** control group and lactobacillus control group,for competitive inhibition test between *** and lactobacillus.[Result]Totally 34 strains with similar characteristics to *** strains were preliminarily screened;the target band amplified by PCR was 293 bp,which was consistent with the expected *** isolated strain could decompose maltose,sucrose,lactose,glucose,arabinose,mannitol and sorbitol;the nitrate reduction test was positive,while citrate and V-P test was negative,consistent with the biochemical characteristics of *** resistance rate of the isolates to cefalexin and tylosin was over 65%,and that to enrofloxacin and doxycycline was up to 50%;the isolates were more sensitive to apramycin,tilmicosin,neomycin and colistin,and the total resistance rate was below 15%.The inhibitory effects of mixed culture of lactobacillus and *** against *** was better than first colonization of lactobacillus at 24 h;the inhibitory effects of first colonization of lactobacillus against *** was better than that of mixed culture of lactobacillus and *** at 36 h;the inhibitory effects of mixed culture of lactobacillus and *** against *** was the best at 48 h.[Conclusion]The isolated strains of *** were generally resistant to eight commonly used *** could
