目的对雪松Cedrus deodara松针正丁醇部位的化学成分进行研究。方法利用硅胶柱及Sephadex LH-20凝胶色谱柱分离、纯化,并根据理化性质及波谱数据进行结构鉴定。结果从雪松松针正丁醇部位分离得到10个化合物,分别鉴定为1-(4′-羟基-3′-甲氧基苯基)-2-[4″-(3-丙醇基)-2″-甲氧基苯基]-1,3-丙二醇(1)、(7S,8R)-9,9′-二羟基-3,3′-二甲氧基-7,8-二氢苯并呋喃-1′-丙醇基新木脂素-4-O-β-D-葡糖苷(2)、(7R,8R)-3′,9,9′-三羟基-3-甲氧基-7,8-二氢苯并呋喃-1′-丙醇基新木脂素-4-O-α-L-鼠李糖苷(3)、(6R,9R)-6-羟基3-oxo-α-ionol-9-O-β-D-glucopyranoside(4)、(6R,9R)-3-oxo-α-ionol-9-O-β-D-glucopyranoside(5)、莽草酸正丁酯(6)、奎宁酸正丁酯(7)、(6S,9R)-6-hydroxy-3-oxo-α-ionol-9-O-β-D-glucopyranoside(8)、5-p-trans-coumaroylguinic acid(9)、(E)-1-O-对香豆酰基-α-D-吡喃葡萄糖苷(10)。结论化合物1～7为首次从该属植物中分离得到。
Objective To study the chemical constituents of n-butanol in Cedrus deodara pine needles. Methods The compounds were isolated and purified by silica gel column and Sephadex LH-20 gel column chromatography. Their structures were elucidated on the basis of physico-chemical properties and spectral data. Results Ten compounds were isolated from the n-butanol fraction of cedar pine needles and identified as 1- (4’-hydroxy-3’-methoxyphenyl) -2- [4 “ ”-methoxyphenyl] -1,3-propanediol (1), (7S, 8R) -9,9’-dihydroxy- 3,3’- dimethoxy-7,8-dihydrobenzo (2R), (7R, 8R) -3 ’, 9,9’-trihydroxy-3-methoxy-furan- (3), (6R, 9R) -6-hydroxy 3-oxo-α, 7,8-dihydrobenzofuran- -ionol-9-O-β-D-glucopyranoside (4), (6R, 9R) -3-oxo-α-ionol- (7), (6S, 9R) -6-hydroxy-3-oxo-α-ionol-9-O-β-D-glucopyranoside (8), 5-p-trans-coumaroylguinic acid (9), (E) -1-O-para-coumaroyl-α-D-glucopyranoside (10). Conclusion Compounds 1 ~ 7 were isolated from this genus for the first time.
