马尾松松针中化学成分的分离与鉴定(英文)

ISOLATION AND STRUCTURE IDENTIFICATION OF THE CHEMICAL CONSTITUENTS FROM PINE NEEDLES OF PINUS MASSONIANA LAMB.

利用DiaionHP 2 0、ToyopearlHW 4 0及硅胶柱色谱进行分离纯化 ,研究松科 (Pinaceae)植物马尾松(PinusmassonianaLamb .)松针的化学成分。从马尾松松针水煎液的正丁醇部位分离得到了 4个化合物 ,根据理化性质和光谱数据分别鉴定为 :(7S ,8R) 4 ,9′ 二羟基 3,3′ 二甲氧基 7,8 二氢苯并呋喃 1′ 丙基新木脂素 9 O β D 吡喃葡萄糖苷 (1) ,对羟基苯基 2 丁酮 (2 ) ,香草酸 (3) ,氢醌 (4)。这 4个化合物均为首次从本植物中分离得到。

To study the chemical constituents from the water-extracts of pine needles of Pinus massoniana Lamb.,various column chromatography with Diaion HP-20,Toyopearl HW-40 and silica gel were employed for the isolation and purification of compounds from pine needles.Four compounds were isolated from the n-BuOH fraction of water-extracts,their structures were identified by physiochemical properties and spectral analysis as(7S,8R)-4,9′-dihydroxyl-3,3′-dimethoxyl-7,8-dihydrobenzofuran-1′-propylneoligan-9-O-β-D-glucopyranoside(1),4-(4′-hydroxybenzyl)-2-butanone(2),vanillic acid(3),hydroquinone(4).These four compounds were isolated from this plant for the first time.
