Isolation and purification of macrocyclic components from Penicillium fermentation broth by high-speed counter-current chromatography.
Xiang Gao,Rongqiang Zhuang,Jian-Nan Guo,Jian Bao,Mei-Juan Fang,Yan Liu,Pengxiang Xu,Yufen Zhao,Yufen Zhao +8 more
TL;DR: High-speed counter-current chromatography (HSCCC), assisted with ESI-MS, was first successfully applied to the preparative separation of three macrolide antibiotics from the crude extract of the microbe Penicillium SHZK-15, demonstrating that HSCCC is a fast and efficient technique for systematic isolation of bioactive compounds from the microbes.

Synthesizing method for propyl-glutdipeptide
Yufen Zhao,Guo Tang,Ning Zhou +2 more
- 22 Jan 2003
TL;DR: The synthesis process of propyl-glut dipeptide includes the reaction of amino acid with protected N end with triphenyl phsophate and hexachloroethane in organic solvent to form active ester; the reaction between the active esters and glutamine in mixed solution of organic solvent and water solution of inorganic alkali; acidification with inorganic acid and elimination of the N end protecting radical as discussed by the authors.
