1887 D. Hooper in Nature 14 Apr. 566/2 The body just described has the characteristics of an organic acid related in some particulars to chrysophanic acid, but having some distinctly peculiar reactions, and possessing the anti-saccharine property ascribed to the leaves. I propose to call it Gymnemic acid.
