title: Novel secoiridoid lactones from Jasminum multiflorum.
abstract: Four new secoiridoid lactones, jasmolactones A [1], B [2], C [3], and D [4], were isolated from the aerial part of Jasminum multiflorum. The structures of these compounds, which contain a novel bicyclic 2-oxo-oxepano[4,5-c]pyran ring system, were established by spectral analyses and chemical correlations. Pharmacological testing revealed that jasmolactones B and D possess coronary vasodilating and cardiotropic activities.
