摘 要:采用正、反相硅胶柱色谱,凝胶柱色谱,薄层制备及高效液相色谱等分离方法,对中药山慈菇来源之-——云南独蒜兰假鳞茎的乙醇提取物的乙酸乙酯萃取部位的化学成分进行了研究,分离得到14个化合物,其中二氢菲类5个,联苄类4个,三萜类2个,苯丙酸类3个;根据化合物的理化性质与波谱数据分别鉴定为4,7-二羟基_2-甲氧基-9,10-二氢菲(1),4,7-二羟基-1-(p-羟苄基)-2-甲氧基-9,10-二氢菲(2),(2,3-trans)-2-(4-hydroxy-3-methoxypheny|)-3-hydroxymethyl-10-methoxy-2,3,4,5-tetrahydro—phenanthro[2,1-b]furan-7-ol(3),pleionesinB(4),blestriareneA(5),山药素11I(6),3,3’-二羟基-2-(p-羟苄基)-5-甲氧基联苄(7),3’,5-二羟基乏-(p-羟苄基)-3-甲氧基联苄(8),3,3’-二羟基_2,6-二(p-羟苄基)-5-甲氧基联苄(9),tfiphlld(10),pholidotin(11),对羟基反式桂皮酸(12),反式阿魏酸(13),反式阿魏酸二十六烷基酯(14)。化合物5,10—14为首次从独蒜兰属分离得到。This study was to investigate the chemical constituents from pseudobulbs of Pleione yunnanensis, one of the source of traditional Chinese medicine " Shancigu". The chemical constituents were isolated by various chromatography methods, including silica gel, ODS, Sephadex LH-20, and semi-preparative HPLC. Fourteen compounds were isolated and identified from the EtOAc fraction of 90% ethanol extract, including five dihydrophenanthrenes, four bibenzyls, two triterpenoids, and three phenylacrylic acids. Their structures were identified on the basis of the spectral data as 4, 7-dihydroxy-2-methoxy-9,10-dihydrophenanthrene ( 1 ) , 4, 7-di- hydroxy-l-(p-hydroxybenzyl)-2-methoxy-9,10-dihydrophenanthrene (2), (2,3-trans)-2-(4-hydroxy-3-methoxyphenyl)-3-hydroxym- ethyl- 10 -methoxy-2,3,4,5-tetrahydro-phenanthro [ 2,1 -b ] furan-7-ol ( 3 ), pleionesin B (4), b|estriarene A ( $ ), batatasin III ( 6 ), 3, 3 '-dihydroxy-2- (p-hydroxybenzyl) -5-methoxybibenzyl ( 7 ), 3', 5-dihydroxy-2- ( p-hydroxybenzyl ) -3-methoxybibenzyl ( 8 ), 3,3 '-di- hydroxy-2,6-bis (4-hydroxybenzyl) -5-methoxybihenzyl (9), triphyllol ( 10 ), pholidotin ( 11 ), (E) -p-hydroxycinnamic acid ( 12 ), (E)-ferulic acid (13) , and (E)-ferulic acid hexacosyl ester( 14 ). Compounds 5,10-14 were separated from this plant for the first time.
