Pinitol is a cyclitol, a cyclic polyol. It is a known anti-diabetic agent isolated from Sutherlandia frutescens leaves.[1][2] Gall plant tannins can be differentiated by their content of pinitol.[3] It was first identified in the sugar pine (Pinus lambertiana),[4] it is also found in other plants, such as in the pods of the carob tree.[5]

Certain variants of the bacteria Pseudomonas putida have been used in organic synthesis, the first example being the oxidation of benzene, employed by Steven Ley in the synthesis of (+/-)pinitol.[6]

Glycosides[edit]

Ciceritol is a pinitol digalactoside that can be isolated from seeds of chickpea, lentil and white lupin.[7]

A cyclitol derivative can be found in the marine sponge Petrosia sp.[8]
