摘要
The structure of a new compound 5, isolated from the juice of ripe black olives (Olea europaea, cv. Leccino), was elucidated. In unripe green olives oleuropein [1] is present as the major o-diphenolic compound, while in ripe olives demethyloleuropein [6] predominates. Both these glucosides disappear from olive juice, as they are hydrolyzed by native beta-glucosidases. Demethyloleuropein aglycone M rapidly eliminated the carboxyl group, giving 5. Acid methanolysis of 5 gives 8, which supports the assigned structure.
