R( − )pantoyllactone- β-d-glucopyranoside: Characterization of a metabolite from rice seedlings

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-glucopyranosi...

Zusammenfassung: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.
