A new derivative of pantoic acid, R(-)pantoyllactone-β-D-glucopyranoside, has been isolated from rice seedlings and its structure determined. β-Glucosidase hydrolysed it to D-glucose and R(-)pantoyllactone.Alkaline hydrolysis converted it to the salt of 2-R(-)pantoic acid β-D-glucopyranoside.It accumulated in rice shoots but not in roots. - Keywords: Oryza sativa; Gramineae; rice seedling; pantoyllactone glucoside; pantoic acid glucoside; new metabolite; NMR signal assignment; shoot to root distribution.
