色谱研究的最新重要进展

细内径毛细管柱自由溶液用于分离宽范围DNA片段 凝胶电泳是分离DNA最高效的方法,但将凝胶注入微纳分离通道或细内径毛细管柱内存在很大的技术难度。为了克服这一技术难题,美国University of Oklahoma的Shaorong Liu和University of Texas at Arlington的P．K．Dasgupta等在无胶、无管壁改性和无外加电场的情况下

一种酶解与超临界萃取联用制备天然玉米黄素的方法

本发明涉及一种酶解与超临界萃取联用制备天然玉米黄素的方法，具体地说是利用酶解反应与超临界萃取联用的方法从锦灯笼、枸杞子、辣椒、玉米、菠菜等植物中提取天然玉米黄素。将植物先酶解再超临界萃取、干燥后得到天然玉米黄素，即可得到天然玉米黄素。本发明将酶解与超临界萃取相结合，工艺简单、效率高、有机溶剂用量少、玉米黄素收率高，可应用于食品、保健食品、药品、化妆品等领域，具有良好的工业应用前景

Preparation and evaluation of a novel chiral stationary phase based on covalently bonded chitosan for ligand-exchange chromatography

A novel chiral stationary phase based on chitosan covalently bonded onto silica gels has been prepared and used for the separation of various alpha-amino acid enantiomers as well as alpha-hydroxycarboxylic acid enantiomers by chiral ligand-exchange chromatography with copper(II) as a complexing ion. The methanol content and copper(II) ion concentration in the eluent affected retentivity and enantioselectivity. Furthermore, a plausible chiral recognition mechanism for resolution of alpha-amino acids was proposed
