In vitro digestion and human gut microbiota fermentation of Bletilla striata polysaccharides and oligosaccharides.

ABSTRACT:

Background

Bletilla striata is one of the commonly used traditional Chinese medicine. B. striata polysaccharides (BP) and oligosaccharides (BO) are one of the main components of B. striata, which have been proved to have a variety of biological activities. However, the digestion and fermentation characteristics of BP and BO are still unclear.

Methods

The study evaluated different prebiotic effects of BP and BO by in vitro simulating digestion and gut microbiota fermentation.

Results

The results show that the simulating saliva partly degraded BP, but had no effect on BO. The molecular weights of BP and BO remained basically unchanged in gastric and intestinal digestion. In addition, BP and BO could be rapidly degraded and utilized by gut mic
