Phenolic glucosides and a gamma-lactone glucoside from the sprouts of Crocus sativus.

Two new phenolic glucosides, a new gamma-lactone glucoside, and adenosine were isolated from the sprouts of CROCUS SATIVUS L. The new compounds were characterized as 2,4- dihydroxy-6-methoxyacetophenone-2beta-D-glucopyranoside, 2,3,4-trihydroxy-6-methoxyacetopenone-3-beta-D-glucopyranoside and 3-( S)-3-beta-D-glucopyranosyloxybutanolide, respectively. All structures were elucidated on the basis of chemical and spectroscopic evidence.
