The flavonoid fraction of Tephrosia purpurea (FFTP) was studied for its effect on cellular and humoral functions and on macrophage phagocytosis in mice. Oral administration of FFTP (10-40 mg/kg) significantly inhibited sheep red blood cells (SRBC)-induced delayed-type hypersensitivity reactions. It also produced a significant, dose-related decrease in sheep erythrocyte-specific haemagglutination antibody titre. However, the fraction failed to show a significant change in the macrophage phagocytic activity. The results obtained indicate the ability of the flavonoidal fraction of T. purpurea to modulate both the cell-mediated and the humoral components of the immune system.
