GLUCOSE TOLERANCE FACTOR AND METHOD OF MAKING SAME

摘要

A glucose tolerance factor which reduces blood sugar in mammals and is derived from yeast. The glucose tolerance factor can be isolated from autolyzed brewer's yeast extract by sequential fractionation on Sephadex* G-75, Biogel* P-6, and Biogel P-2, to give a purified glucose tolerance factor. By further purification, a substantially purified glucose tolerance factor is obtained which is a quinoline derivative with a molecular ion at 174 by mass spectrometry. *trade marks A3.2.txt 103186
