Water-soluble constituents of fennel. IX. Glucides and nucleosides

Abstract

From the water-soluble portion of the methanolic extract of fennel, seven new sugar alcohols (two deoxybutitols, four deoxypentitols and one deoxyhexitol) and a sugar lactone were isolated, together with seven known glucides, four nucleosides, (3R)-2-hydroxymethylbutane-1,2,3,4-tetrol and uracil. From the results of spectral investigation, the new compounds were characterized as 1-deoxythreitol (9), (2R)-butane-1,2,4-triol (10), 1-deoxy- D-ribitol (11), 1-deoxy-o-xylitol (12), 2-deoxy-D-ribitol (13), 3- deoxyarabinitol (14), 1-deoxy-D-glucitol (16) and 2-deoxy-D-ribono-1,4- lactone (15), respectively.
