Pinitol is a cyclitol, a cyclic polyol. It is a known anti-diabetic agent isolated from ''Sutherlandia frutescens'' leaves.〔Narayanan, 1987〕〔(Introduction Sutherlandia frutescens - Kankerbossie )〕 Gall plant tannins can be differentiated by their content of pinitol. It was first identified in the sugar pine (''Pinus lambertiana'').
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.〔Microbial oxidation in synthesis: A six step preparation of (+/-)-pinitol from benzene, S. V. Ley et al., Tetrahedron Lett. Volume 28, 1987, Pages 225 〕

Ciceritol is a pinitol digalactoside that can be isolated from seeds of chickpea, lentil and white lupin.〔(Ciceritol, a pinitol digalactoside from seeds of chickpea, lentil and white lupin; Phytochemistry, Volume 22, Issue 8, 1983, Pages 1745-1751 )〕
A cyclitol derivative can be found in the marine sponge ''Petrosia'' sp.〔(A cyclitol derivative as a replication inhibitor from the marine sponge Petrosia sp. Kim D.-K.; Young Ja Lim; Jung Sun Kim; Jong Hee Park; Nam Deuk Kim; Kwang Sik Im; Jongki Hong; Jung J. H. Journal of natural products, 1999, vol. 62, no5, pp. 773-776 )〕
