Resum
By use of 1H and 13C NMR spectroscopy including 2D 1H,1H DQF-COSY/TOCSY and 1H,13C HMQC/HMBC experiments, the main water-soluble carbohydrate components extracted from leaves of Matricaria maritima were identified as oligofructans composed of a linear chain of (2-->1)-linked beta-D-fructofuranosyl residues specifying an inulin-type structure. Alpha-D-Glcp-(1-->2)-[beta-D-Fruf-(2-->1)-beta-D-Frucf]n-(2-->1)-beta-D-Fruf.
