| Objective To study the chemical constituents of fish glue and its improvement effect on cyclosphamide induced anemia in mice. Methods The contents of total polysaccharide were measured by phenol-sulphate acid method, the monosaccharide composition was analyzed using pre-column derivativehigh performance liquid chromatography method, Kjeldahl method was used to determine the nitrogen and protein content, amino acid composition was measured by an automatic amino acid analyzer, auto fat analyzer was used to determine the crude fat, fatty acid composition was analyzed using gas chromatography-mass spectrometry method, mineral elements were determined by inductively coupled plasma mass spectrometry. Pepsin-soluble collagen was extracted from fish glue using hydrochloric acid-pepsin methodology, its collagen content and detailed structure were analyzed. Improve anemia model was established by intrapertoneal injection of high-dose cyclophosphamide. The effects of fish glue by intragastrical administration on blood cells and visceral index. Results The contents of total polysaccharide, protein, crude fat and collagen were 0～0.4%, 97.0～98.1%, 1.0～1.8% and 11.2～73.5%, respectively. The results showed that the main monosaccharide in polysaccharides of fish glue were glucose and galactose, contained seventen kinds of amino acids including seven essential amino acids, palmitic acid, stearic acid and oleic acid were the main fatty acids, the content of Ca was the highest, and the content of Fe, Zn, Cu, Mn, Se was higher than others. The most abundant amino acid in fish glue collagen was glycine. The SDS-PAGE result showed that the fish glue collagen possessed three kinds of chains (α, β and γ) and the molecular weight was about 135, 200 and 245 kDa, respectively. In addition, the ultraviolet absorption spectrum, fourier transform infrared spectrum and circular dichrosim spectrum results accorded with the characteristics of type Ⅰ collagen. Fish glue could promote the recovery of thymus index, red blood cells, hemoglobin and thrombocyte content. Conclusion The chemical constituents of fish glue were studied systematically for the first time, fish glue could promote the recovery of hematopoietic function in model mice, and will provide evidence for the further study of the effective substances in fish glue. |
