Abstract
[GRAPHICS] Two novel sesquiterpene and monoterpene dimers, macrophyllols A (1) and B ( 2), were isolated from the bark of Inula macrophylla, Their structures were determined on the basis of spectral evidence (especially HREIMS and 2D NMR ) as well as chemical transformation. The structure of macrophyllol A (1) w as confirmed by X-ray analysis. The possible biosynthetic pathways of macro phyllols A (1) and B (2) are discussed.
