Abstract:
:Callus extracts of Crocus sativus exhibited the ability to transform all-trans-crocetin into its related glycosides between pH 7.0 and 7.6 in the presence of uridine-diphospho-glucose. The reactions involved the step-wise addition of a glucose moiety to a free carboxyl function and the 1-->6 addition of a glucose moiety to a glucosyl ester function. The kinetics of synthesis for each glycoside seemed to indicate that two distinct glucosyl transferases were implicated in the synthesis of crocin, all-trans-crocetin di-(beta-D-gentiobiosyl) ester.
