Seven new sucrose and oligosaccharide esters, glomeratoses A-G, together with four known compounds, 3-O-[(E)-3,4,5-trimethoxycinnamoyl]-beta-D-fructofuranosyl-(2-->1) - (6-O-benzoyl)-alpha-D-glucopyranoside, 3-O-(E)-sinapoyl-beta-D-fructofuranosyl-(2-->1)-[6-O-(E)-sinapo yl]-alpha-D- glucopyranoside, tenuifoliside C and reiniose G were isolated from the roots of Polygala glomerata. Glomeratoses A-G were elucidated as 3-O-[(E)-3,4,5-trimethoxycinnamoyl]-beta-D-fructofuranosyl-(2-->1) -alpha-D- glucopyranoside, 3-O-(E)-sinapoyl-beta-D-fructofuranosyl-(2-->1)-[6-O-(E)-p- coumaroyl]-alpha-D-glucopyranoside, 3-O-[(E)-3,4,5-trimethoxycinnamoyl]-beta-D-fructofuranosyl-(2-->1) -[6-O-(E)- p-coumaroyl]-alpha-D-glucopyranoside, 3-O-[(E)-3,4,5-trimethoxycinnamoyl]-beta-D-fructofuranosyl-(2-->1) -[6-O-(E)- 3,4,5-trimethoxycinnamoyl]-alpha-D-glucopyranoside, 1-O-{6-O-[3-O-(E,E)-(beta, beta'-bis-sinapoyl)-beta-D-fructofuranosyl]}-alpha- D-glucopyranoside intramolecular ester, 1-O-(E)-p-coumaroyl-(3-O-benzoyl)-beta-D- fructofuranosyl-(2-->1)-[beta-D-glucopyranosyl-(1-->2)]-[6-O-acetyl-beta -D- glucopyranoysl-(1-->3)]-[4-O-(E)-feruloyl]-(6-D-acetyl)-alph a-D- glucopyranoside, 1-O-(E)-p-coumaroyl-(3-O-benzoyl)-beta-D-fructofuranosyl-(2-->1)-[ beta-D- glucopyranosyl-(1-->2)]-[6-O-acetyl-beta-D-glucopyranoside-(1-->3)]-{4-O - [4-O-beta-D-glucopyranosyl-(E)-feruloyl]}-[6-O-(E)-p-coumaroyl+ ++]-alpha- D-glucopyranosyl, respectively, on the basis of chemical and spectral evidence.
从黄花倒水莲的根部分离出7种新的蔗糖和寡糖酯，即glomeratoses A - G，以及4种已知化合物，3 - O - [(E) - 3,4,5 - 三甲氧基肉桂酰基] - β - D - 呋喃果糖基 - (2→1) - (6 - O - 苯甲酰基) - α - D - 吡喃葡萄糖苷、3 - O - (E) - 芥子酰基 - β - D - 呋喃果糖基 - (2→1) - [6 - O - (E) - 芥子酰基] - α - D - 吡喃葡萄糖苷、细叶远志苷C和重楼皂苷G。基于化学和光谱证据，glomeratoses A - G分别被鉴定为3 - O - [(E) - 3,4,5 - 三甲氧基肉桂酰基] - β - D - 呋喃果糖基 - (2→1) - α - D - 吡喃葡萄糖苷、3 - O - (E) - 芥子酰基 - β - D - 呋喃果糖基 - (2→1) - [6 - O - (E) - 对香豆酰基] - α - D - 吡喃葡萄糖苷、3 - O - [(E) - 3,4,5 - 三甲氧基肉桂酰基] - β - D - 呋喃果糖基 - (2→1) - [6 - O - (E) - 对香豆酰基] - α - D - 吡喃葡萄糖苷、3 - O - [(E) - 3,4,5 - 三甲氧基肉桂酰基] - β - D - 呋喃果糖基 - (2→1) - [6 - O - (E) - 3,4,5 - 三甲氧基肉桂酰基] - α - D - 吡喃葡萄糖苷、1 - O - {6 - O - [3 - O - (E,E) - (β,β' - 双芥子酰基) - β - D - 呋喃果糖基]}-α - D - 吡喃葡萄糖苷分子内酯、1 - O - (E) - 对香豆酰基 - (3 - O - 苯甲酰基) - β - D - 呋喃果糖基 - (2→1) - [β - D - 吡喃葡萄糖基-(1→2)] - [6 - O - 乙酰基 - β - D - 吡喃葡萄糖酰基-(1→3)] - [4 - O - (E) - 阿魏酰基] - (6 - D - 乙酰基) - α - D - 吡喃葡萄糖苷、1 - O - (E) - 对香豆酰基 - (3 - O - 苯甲酰基) - β - D - 呋喃果糖基 - (2→1) - [β - D - 吡喃葡萄糖基-(1→2)] - [6 - O - 乙酰基 - β - D - 吡喃葡萄糖苷-(1→3)] - {4 - O - [4 - O - β - D - 吡喃葡萄糖基 - (E) - 阿魏酰基]}-[6 - O - (E) - 对香豆酰基] - α - D - 吡喃葡萄糖基。
