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.
首次从黄花烟草的表面脂质中分离并鉴定出三种蔗糖酯。它们含有乙酸以及5-甲基己酸、5-甲基庚酸和6-甲基庚酸等支链短链脂肪酸。这些蔗糖酯的结构分别为6-O-乙酰基-4-O-酰基-α-D-吡喃葡萄糖基-4,6-O-二乙酰基-3-O-酰基-β-D-呋喃果糖苷、4-O-酰基-α-D-吡喃葡萄糖基-1,4-O-二乙酰基-3-O-酰基-β-D-呋喃果糖苷和6-O-乙酰基-4-O-酰基-α-D-吡喃葡萄糖基-4-O-乙酰基-3-O-酰基-β-D-呋喃果糖苷。
