inulin

A polysaccharide with the general formula (C₆H₁₀O₅)_n that is found in the roots of various composite plants and yields fructose when hydrolyzed.

A vegetable principle (C₆H₁₀O₅) which is spontaneously deposited from a decoction of the roots of Inula Helenium and certain other plants.

A substance of very wide occurrence. It is found dissolved in the sap of the roots and rhizomes of many composite and other plants, as Inula, Helianthus, Campanula, etc., and is extracted by solution as a tasteless, white, semicrystalline substance, resembling starch, with which it is isomeric, having fructose units in place of most of the glucose units. It is intermediate in nature between starch and sugar, and replaces starch as the reserve food in Compositae. Called also dahlin, helenin, alantin, alant starch, etc.

a polysaccharide found in the roots and tubers of certain plants, especially the Compositae; it is mostly a polymer of fructose

used to manufacture fructose and in assessing kidney function
