Research Abstract

There was no detailed information about physiological function of galactoglucomannan found in apple flesh. Different types of oligosaccharides prepared from apple galactoglucomannan, konjak glucomannan, guar gum and locust bean gum were tested for effects on the growth of COLO201 and DLD-1 human tumor cells. The cell growth of COLO201 was reduced by some oligosaccharides from apple galactoglucomannan and guar gum.
