摘要
从观光木(Tsoongiodendron odorum Chun)茎枝的80%乙醇提取物中分离得到11个酚性化合物,经波谱鉴定为:对羟基苯甲醛(1)、香草醛(2)、1,3,5-三甲氧基苯(3),丁香醛(4)、香草酸(5)、苏式-2,3-二-(4-羟基-3-甲氧基苯)-3-甲氧基丙醇(6)、赤式-2,3-二-(4-羟基-3-甲氧基苯)-3-甲氧基丙醇(7)、丁香酸(8)、3-羟基-1-(4-羟基-3,5-二甲氧基苯)-1-丙酮(9)、对羟基苯乙醇(10)和C-veratroylglycol(11)。其中,化合物1~4和6~11为首次从该植物中分离得到。
Eleven phenolic constituents were isolated from the 80% ethanol extract of the twigs of Tsoongiodendron odorum Chun.On the basis of spectroscopic methods,their structures were identified as p-hydroxybenzaldehyde(1),vanillin(2),1,3,5-trimethoxybenzene(3),4-hydroxy-3, 5-dimethoxy-benzaldehyde(4),vanillic acid(5),threo-2,3-bis-(4-hydroxy-3-methoxyphenyl)-3methoxy-propanol(6),erythro-2,3-bis-(4-hydroxy-3-methoxyphenyl)-3-methoxy-propanol(7),syringic acid(8), 3-hydroxy-1-(4-hydroxy-3,5-dimethoxyphenyl)-1-propanone(9),p-hydroxyl phenethanol(10),and C-veratroylglycol(11).Compounds 1-4 and 6-11 were isolated from this plant for the first time.
