A new furostanol glycoside (2), named sativoside-B1, was isolated from garlic, bulbs of Allium sativum L., along with proto-desgalactotigonin (3).The structure of 2 was established to be (25R)-26-O-β-D-glucopyranosyl-22-hydroxy-5α-furostane-3β,6β,26-triol 3-O-β-D-glucopyranosyl-(1->3)-O-β-D-glucopyranosyl-(1->2)-O-3)-O-β-D-glucopyranosyl-(1->4)-O-β-D-galactopyranoside.From roots of this plant, two new steroidal glycosides, named sativoside-R1 (16) and sativoside-R2 (15) were isolated and their structures were determined to be (25R)-26-O-β-D-glucopyranosyl-22-hydroxy-5α-furostane-3β,26-diol 3-O-β-D-glucopyranosyl-(1->3)-O-β-D-glucopyranosyl-(1->2)-O-3)>-O-β-D-glucopyranosyl-(1->4)-O-β-D-galactopyranosyde (16) and its corresponding spirostanol glycoside (15).Besides these glycosides, three known glycosides, 3, desgalactotigonin (13) and F-gitonin (14) were isolated and identified.In a glycoside fraction of the leaves of A. sativum, steroidal glycosides were not detected by thin layer chromatography analysis.
