However, despite many attempts,it is only within the last few years that progress has been made toward the successful cyclization of hexose derivatives to inositol derivatives. Ferndndez, Izquierdo and Martinez " have reported the presence of a cyclase in the leaves of Lactuca virosa L. which converts D-glucose to a material giving the Scherer test for inositol. Since this color test is general for the inositols a definite statement regarding the nature of the product will have to await its isolation and identification.
