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

From the water-soluble portion of the methanolic extract of fennel, seven n ew sugar alcohols (two deoxybutitols, four deoxypentitols and one deoxyhexi tol) and a sugar lactone were isolated, together with seven known glucides, four nucleosides, (3R)-2-hydroxymethylbutane-1,2,3,4-tetrol and uracil. Fr om the results of spectral investigation, the new compounds were characteri zed as 1-deouythreitol (9), (2R)-butane-1,2,4-triol (10), 1-deoxy-D-ribitol (11), 1-deoxy-D-xylitol (12), 2-deoxy-o-ribitol (13), 3-deoxyanabinitol (14 ), 1-deoxy-D-glucitol (16) and 2-deoxy-D-rihono-1,4-lactone (15), respectiv ely.
