Studies on Sesquiterpenes from Macroclinidium trilobum MAKINO. II

Abstract

Four new guaiane-type sesquiterpene glycosides, macroclinisides F (II), G (III), H (IV) and I (V), and a new phenyl propanoid glycoside, 4-allyl-2, 6-dimethoxyphenol glucoside (VI), have been isolated from Macroclinidium trilobum MAKINO together with isolipidiol (I). The structures were determined on the basis of chemical and spectral data.
