Isolation and NMR-Spectroscopic Investigations of (-)-1-O-Benzyl-β-D-primveroside from Green Fruits of Prunus laurocerasusThe TLC of the acetylated aqueous extracts of the green fruits of Prunus laurocerasus reveals two spots corresponding to pentaacetyl-glucopyranose and hexaacetyl-1-O-benzyl-β-D-primveroside (2), which can be quantitatively separated by flash chromatography. Saponification of 2 yields the free 1-O-benzyl-β-D-primveroside (1) which affords D-primverose (3) upon hydrogenolysis. The direct hydrogenolysis of 2 yields hexaacetyl-β-D-primverose (4). The structures of compounds 1-4 have been verified by NMR spectroscopy.
