below12.5 mmol/L after 120 min. The glucose levels of these mice werestatistically equal to that of Xiaoke pill (reduction of 31.26%). MCP-H showed a higher hypoglycemic effect (Fig. 3). On the other hand,no significant difference in BGL was observed for the normal micetreated with the extract when compared to 0 min of this group.After 120 min, no significant difference was observed between theblood levels of the mice treated with the MCP and those treatedwith the standard drugs. These results clearly indicated that MCPcould improve glucose tolerance of alloxan-induced diabetic mice.
