نبذة مختصرة
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.
