Summary

自动翻译

The objective is to fractionate and isolate bioactive small molecules, peptides from a complex plant extract, and proteins from pathogenic microbes by employing liquid-phase isoelectric focusing (IEF) method. Further, the separated molecules were identified and their bioactivity confirmed.
