Three New Depsidones From the Lichen Neofuscelia subincerta

Abstract

The depsidones , glomelliferonic acid (4)(8-hydroxy-3-methoxy-ll-oxo-l-(2-oxopentyl)-6- pentyl -11H-dibenzo[ b,e ] [1,4]dioxepin-7-carboxylic acid), loxodellonic acid (5) (8-hydroxy-3-methoxy-11-oxo-1-(2-oxopenty1)-6-propyl-llH-dibenzo[ b,e ][l,4]dioxepin-7-carboxylic acid) and glomellonic acid (6) (8-hydroxy-3-methoxy-1l-oxo-l,6-di(2-oxopentyl)-11H- dibenzo [ b,e ][l,4]dioxepin-7-carboxylic acid), have been isolated from the lichen Neofuscelia subincerta ( Essl .) Essl . and characterized.
