Sucrose esters from the surface lipids of Nicotiana cavicola.
Three sucrose esters were isolated and identified for the first time from the surface lipids of Nicotiana cavicola. They contained acetic acid and such branched short-chain fatty acids as 5-methylhexanoic, 5-methylheptanoic, and 6-methylheptanoic acids. The structures of the sucrose esters were 6-O-acetyl-4-O-acyl-alpha-D-glucopyranosyl-4,6-O-diacetyl-3-O-acyl-beta- D- fructofuranoside, 4-O-acyl-alpha-D-glucopyranosyl-1,4-O-diacetyl-3-O-acyl-beta-D-fructofur anoside and 6-O-acetyl-4-O-acyl-alpha-D-glucopyranosyl-4-O-acetyl-3-O- acyl-beta-D-fructofuranoside.
