PurposeThe main components , stability and its stimulating immunity on mice of chlorella growth factor (CGF) were investigated in this study.MethodsCGF was extracted from cells of chlorella with enzyme.ResultsCGF contained 56.6% protein, 42.59% amino acid, 6.8% nucleoside acid, 4.8% polysaccharide and 1.7% vitamin. Mice were fed with CGF at the rates of 75, 150 and 450 mg/(kg·d) in the experiment of stimulating immunity function. The results showed that applying CGF at the rates of 150 and 450 mg/(kg·d) could increase allergic reaction induced by dinitrofuorobenzene, enhance the proliferation of immunoinhibited murine splenocytes, and stimulate phagocytic function by macrophages.ConclusionCGF could be used for function food to enhance human′s immunity.
