Abstract
Investigation of the crude drug "Ye su xin", the dried flowers of Jasminum polyanthum, has led to the isolation of eight secoiridoid glucosides esterified with a linear monoterpene unit, jaspofoliamosides C-G, jaspogeranosides A and B, and jaspolinaloside B. The structures of these compounds were elucidated on the basis of chemical and spectroscopic evidence.
