A new derivative of pantoic acid, R(-) pantoyllactone-beta-D-glucopyranoside, has been isolated from rice seedlings and its structure determined. beta-Glucosidase hydrolysed it to D-glucose and R(-)pantoyllactone. Alkaline hydrolysis converted it to the salt of 2-R(-)pantoic acid beta-D-glucopyranoside. It accumulated in rice shoots but not in roots.

Abstract

A new derivative of pantoic acid, R(-) pantoyllactone-beta-D-glucopyranoside, has been isolated from rice seedlings and its structure determined. beta-Glucosidase hydrolysed it to D-glucose and R(-)pantoyllactone. Alkaline hydrolysis converted it to the salt of 2-R(-)pantoic acid beta-D-glucopyranoside. It accumulated in rice shoots but not in roots.
