Volemitol is a naturally occurring seven-carbon sugar alcohol.

It is a substance widely distributed in plants, red algae, fungi, mosses, and lichens.

In certain higher plants, such as Primula, volemitol plays several important physiological roles.

It functions as a photosynthetic product, phloem translocate, and storage carbohydrate.

Volemitol was first isolated as a white crystalline substance from the mushroom Lactarius volemus by the French scientist Émile Bourquelot in 1889.
