| Abstract | Short-chain fatty acids (SCFAs) produced by the intestinal bacteria are very critical for the intestinal barrier, mucosal cytoprotection and normal intestinal biology. However, accumulation of SCFAs promoted by the polysaccharides from Chrysanthemum morifolium Ramat remains unknown. Thus, it is necessary to investigate SCFAs in the colonic contents of dextran sulfate sodium (DSS) induced colitis mice after oral administration of the polysaccharides from C. morifolium Ramat which is very helpful to unravel how it works. In this study, a rapid and reliable gas chromatographic method with flame ionization detector (GC-FID) for simultaneous determination of six SCFAs such as acetic acid (AA), propionic acid (PA), butyric acid (BA), isobutyric acid (IBA), valeric acid (VA) and isovaleric acid (IVA) has been developed and validated. Under the optimized chromatographic conditions and sample extraction procedure, good separation for 6 target compounds was obtained on a HP-INNOWAX column within 12min. Results revealed that polysaccharides from C. morifolium Ramat positively affected the SCFAs intestinal production. The polysaccharides group had greater SCFAs concentration in colonic content than the DSS-treated group (P<0.05), which was decreased remarkably compared to the normal group (P<0.01). With the decrease of the polysaccharides dosage, the contents of AA, PA and VA increased gradually, while the change of BA concentration was the opposite. There was no significant difference in the content of IBA at the different administration concentrations. And the content of IVA reached the highest concentration 0.953mg/g at lower dose of the polysaccharides. Additionally, oral administration of the polysaccharides prominently attenuated the body weight loss, reduced the disease activity index, rectal bleeding and stool consistency, improved colon shortening and macroscopic score of colitis. Our results indicated that the polysaccharides of C. morifolium Ramat might be used as prebiotic agents to prevent gut dysbiosis and inflammatory bowel disease. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
