  • Chemical investigation of the inhibitory compound on leucocyte migration from Melilotus officinalis has led to the isolation and characterization of azukisaponin V $(3-O-[{\alpha}-L-rhamonopyranosyl(1{\rightarrow}2)-{\beta}-D-glucopyransosyl(1{\rightarrow}2)-{\beta}-D-glucuronopyranosyl]-soyasapogenol B)$ as the carboxylate form, which exhibits potent leucocyte migration inhibitory activity at a dose of 6mg/rat.
