Eight minor secoiridoid glucosides with a linear monoterpene unit from Jasminum polyanthum

Abstract

Investigation of the crude drug 'Ye su xin', the dried flowers of Jasminum polyanthum, has led to the isolation of eight new 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.
