- Abstract
Two new N-acyl-glycosphingosines (cerebrosides) named longifoside-A {6′-tetracosenamide, N-[3,4-dihydroxy-1-(hydroxymethyl)-2-(β-D-glucopyranosyl) heptadecyl]-(6′ E )} and B {6′-tetracosenamide, N-[3-hydroxy-1-(hydroxymethyl)-2-(β-D-glucopyranosyl)-4 Z -heptadecenyl]-(6′ E )} have been obtained from the methanolic extract of Mentha longifolia belonging to the family Lamiaceae. Both the cerebrosides were purified as their acetate-derivatives: 6′-tetracosenamide, N-[3,4-diacetoxy-1-(acetoxymethyl)-2-(tetraacetoxy-β-D-glucopyranosyl) heptadecyl]-(6′ E ) and 6′-tetracosenamide, N-[3-acetoxy-1-(acetoxymethyl)-2-(tetraacetoxy-β-D-glucopyranosyl)-4 Z -heptadecenyl]-(6′ E ). They were characterized with the aid of 1D and sophisticated 2D-NMR spectroscopic techniques.
