Abstract

Phytochemical investigation of the dried leaves and twigs of Ligustrum vulgare has led to the isolation of the secoiridoid glucosides, (2''R)- and (2''S)-10-hydroxy-2''-methoxyoleuropeins (1 and 2), and the secoiridoid aglycones, ligustrohemiacetals A (3) and B (4). Their structures were elucidated by spectroscopic and chemical means. Enzymatic hydrolysis of 10-hydroxyoleuropein to the analog of ligustrohemiacetals A and B led to the structural revision of jasmolactones.
