Objective To study the effect of the products of entermorpha (EP), chlorella growth factor (CGF) and entermorpha dietary fiber (EPDF) on defecation and blood lipid regulation. Method Based on the composition of EP products, the male ICR mice were intervened with EP, EPDF and CGF with three doses. Using the constipation model induced by compound diphenoxylate, the effect of EP products on enterocinesia function of mice was determined by measuring defecation and the percentage of ink-pushing in small intestine. High-lipid rat model was established by feading high fat diet and the intervention effect with three doses of EPDF and CGF for 6 w was observed. Results As compared to the model group,all doses of EP,both middle and high doses of EPDF,and high dose of CGF could shorten the time of first defecation and increase the percentage of ink-pushing in small intestine of costive mice (P
