A new triterpenoid saponin has been isolated from haricot beans and its structure shown to be 3‐O‐[β‐ D ‐glucopyranosyl(1→2)‐β‐ D ‐galacto‐pyranosyl (1→2)‐β‐ D ‐glucuronopyranasyl] olean‐12‐en‐3β, 22β, 24‐triol. The dietary intakes of saponins are discussed and the possible physiological consequences are identified.
