Abstract :

The chemical structures of 9 compounds isolated from the dried fruits of Prunus domestica L., were elucidated on the basis of NMR and MS analyses. Each isolated compound was determined to be scopolin (1), (3-O-cis-p-coumaroyl-�²-D-fructofuranosyl)- (2â��1)-�±-D-glucopyranoside (2), 1S-(4-�²-D-glucopyranosyl-3-methoxyphenyl)-2R-[4-(3-hydroxypropyl)-2-methoxyphenoxy]-1,3- propanediol (3), �²-D-glucopyranosyl 9-carboxy-8-hydroxy-2,7-dimethyl-2E,4E-nonadienate (4), �²-D-glucopyranosyl 7-carboxy- 2-methyl-2E,4E-octadienate (5), 8-hydroxy-2,7-dimethyl-2E,4E-decadienedioic acid 1-�²-D-glucopyranyl ester 10-methyl ester (6), (3-O-trans-p-coumaroyl-�²-D-fructofuranosyl)-(2â��1)-�±-D-glucopyranoside (7), �²-D-glucopyranosyl cinnamate (8), and 2,7-dimethyl-2E, 4E-octadienedioic acid (9), respectively. Compounds 2, 3, 7, 8, and 9 were isolated from Prunus domestica L., for the first time and compounds 4, 5 and 6 were novel glucosyl terpenates. On the basis of the chemical structures of some isolated compounds from Prunus domestica L., a possible biosynthesis pathway of them was also proposed.
