Myo-inositol is a natural
cyclitol that is mostly obtained from diet but is also synthesized in the kidney.
Inositol is a
cyclitol present in animal and plant cells.

cyclitol derivatives from benzene.
Shikimic acid, commonly known as its anionic form shikimate, is a cyclohexene, a
cyclitol and a cyclohexanecarboxylic acid.
Shikimic acid is a white crystalline
cyclitol, which is a precursor material for industrial synthesis of the important drug, oseltamivir phosphate (Tamiflu), which is an effective drug againstthe H5N1 influenza virus [1], especially if administered early.
Quinic acid (2) is a
cyclitol present in a variety of plant species found in the human diet, such as cabbage (Brassica oleracea L.) and tea (Camellia sinensis L.) (Ferreres et al.
Fagopyritol B1, O-[alpha]-D-galactopyranosyl-(1 [right arrow] 2)-D-chiro-inositol, a galactosyl
cyclitol in maturing buckwheat seeds associated with desiccation tolerance.
1) is a plant derived
cyclitol (Clark, 1936; Lemos et al., 2006) and has similar physiological effects as inositol.
Because buffer, salts, and mannitol (Thorne and Rainbird, 1983) interfered with
cyclitol analysis, unloaded compounds were collected in water.
An oral dose of only 10 mg pinitol/kg body weight significantly lowered blood glucose during a period of 0.5 to 2 h following administration of the
cyclitol. More recent studies have shown that a closely related cyclitol--D-chiro-inositol--administered at the same dose, has similar effects on blood glucose levels (Ortmeyer et al., 1993).
He proposed a role for soluble carbohydrates, including raffinose series of oligosacchaarides and galactosyl
cyclitol oligomers, in maturing seeds and somatic embryos in relation to seed storability, acquisition of desiccation tolerance during seed development and maturation, and loss of desiccation tolerance during germination.
The lack of association between yellowing of axis tissues and galactosyl
cyclitol accumulation during in vitro culture of zygotic embryos, indicates that loss of green color is independent of the biosynthesis of soluble galactosyl oligomers.
