Abstract

Buddlejosides A (1) and B (2), new iridoid galactosides, and buddlejone (3), a benzofuran type sesquiterpene, have been isolated from the EtOAc fraction of Buddleja crispa together with β-sitosterol (4) and ursolic acid (5). Their structures have been assigned on the basis of spectral analyses including 1D and 2D NMR spectral techniques.
