Methods The components were isolated and identified by HPLC, GC, TLC and colorimetry. The relative molecular mass of polysaccharide was determined by HPGPC, and the immunological activity was determined by biological method. Results Carbitine contained approximately 80% of polysaccharides, 5% of nucleic acids, nucleotides, and traces of amino acids; the relative molecular weight of polysaccharides was approximately 300,000; and the percentage of phagocytosis of mouse peritoneal macrophages by xanthan (x±) s) up to (5 3.7 ± 3.3), phagocytic index (x ± s) was (2.7 ± 0.4); rose rose% (average) was 18.0%. Conclusion The main components of this product are polysaccharides and nucleic acids. The quality control can be achieved by measuring its content and activity.
