SUCROSE ESTERS FROM THE SURFACE-LIPIDS OF PETUNIA-HYBRIDA

Three sucrose ester types were isolated and identified from the leaf s urface lipids of Petunia hybrida. They contained both unbranched and b ranched fatty acids (from C2 to C8). Further, one of these sucrose est ers contained malonic acids. The structures of the sucrose esters were ,3,4-O-tri-acyl-alpha-D-glucopyranosyl-1-O-acetyl- beta-D-fructofuran oside, ,3,4-O-tri-acyl-alpha-D-glucopyranosyl-4-O-acetyl- beta-D-fruct ofuranoside and 2,3,4,6-O-tetra-acyl-alpha-D-glucopyranosyl- beta-D-fr uctofuranoside.
