摘  要:对甘青乌头Aconitum tanguticum全草的化学成分进行研究。应用硅胶,ODS,Sephadex LH-20,制备HPLC等各种色谱技术进行分离纯化,采用MS,NMR等波谱技术鉴定化合物结构。甘青乌头乙醇总提取物经石油醚、乙酸乙酯萃取后的剩余水溶液经AB-8大孔吸附树脂,依次用水,30%,60%,95%乙醇洗脱,合并回收溶剂分别得到各洗脱部分。从30%,60%乙醇洗脱部分共分离得到19个化合物,分别鉴定为紫丁香苷(1),香草酸4-O-β-D-阿洛糖苷(2),阿魏酸4-O-β-D-阿洛糖苷(3),阿魏酸4-O-β-D-葡萄糖苷(4),芥子酸4-O-β-D-葡萄糖苷(5),4-羟基-肉桂醇-4-O-β-D-葡萄糖苷(6),槲皮素-3-O-α-L-鼠李糖基-(1→2)-[α-L-鼠李糖基-(1→6)]-β-D-半乳糖苷-7-O-α-L-鼠李糖苷(7),山柰酚-3-O-α-L-鼠李糖基-(1→2)-[α-L-鼠李糖基-(1→6)]-β-D-半乳糖苷-7-O-α-L-鼠李糖苷(8),槲皮素-3-O-α-L-鼠李糖基(1→6)-β-D-半乳糖苷-7-O-α-L-鼠李糖苷(9),山柰酚-3-O-[β-D-葡萄糖基-(1→3)-(4-O-反式-对香豆酰基)]-α-L-鼠李糖基-(1→6)-β-D-半乳糖苷-7-O-α-L-鼠李糖苷(10),槲皮素-3-O-[β-D-葡萄糖基-(1→3)-(4-O-反式-对香豆酰基)]-α-L-鼠李糖基-(1→6)-β-D-半乳糖苷-7-O-α-L-鼠李糖苷(11),红景天苷(12),2-(3,4-二羟基苯基)乙醇1-O-β-D-葡萄糖苷(13),(7S,8R)-去氢二松柏醇-9'-O-β-D-葡萄糖苷(14),citrusin B(15),异叶乌头碱(16),tanaconitine(17),山栀苷甲酯(18)和淫羊藿次苷B1(19)。除化合物4,13,16和17外,其余化合物均为首次从甘青乌头中分离得到。Nineteen compounds were isolated from the whole plants of Aconitum tanguticum by means of various of chromato-graphic techniques such as silica gel, ODS, sephadex LH-20 and preparative HPLC, and their structures were elucidated as syringin ( 1 ), vanillic acid-4-O-β-D-allopyranoside ( 2 ), (E)-fendic acid 4-O-β-D-aUopyranoside ( 3 ), (E)-ferulic acid-4-O-β-glucopysoside (4), (E)-sinapic acid-4-O-β-glucopyranoside ( 5 ), (E)-4-hydroxycinnamyl alcohol 4-O-β-D-glucopyranoside ( 6 ), quercetin 3-O-α-L-rhamnopyranosyl- ( 1→2 ) - [ α-L-rhamnopyranosyl-( 1→6 ) ]-β-D-galactopyranoside-7-O-α-L-rhamnopyranoside ( 7 ), kaempferol 3-O-α-L-rhamnopyranosyl-( 1→2 ) - [ α-L-rhamnopyranosyl-( 1→6 ) ] -β-D-galactopyranside-7-O-α-L-rhamnopyranoside ( 8 ), quercetin 3-O-α-L-rhamnopyranosyl- ( 1→6 )-β-D-glucopyranoside-7-O-α-L-rhamnopyranoside ( 9 ), kaempferol 3-O-[β-D-glucopyranosyl- ( 1→3 ) -( 4-0-trans-p-coumaroyl) ]-α-L-rhamnopyranosyl-( 1→6 ) -β-D-galactopyranside-7-O-α-L-rhamnopyranoside ( 10 ), quercetin 3-O-[ β-D-gluco-pyranosyl-( 1→3 )-( 4-O-trans-p-coumaroyl ) ]-α-L-rhamnopyranosyl-( 1→6 )-β-D-galactopyranoside-7-O-α-L-rhamnopyranoside ( 11 ), salidroside ( 12 ), 2-(3,4-dihydroxyphenyl) ethanol 1-O-β-D-glucopyranoside ( 13 ), ( 7S, 8R)-dehydrodiconiferyl alcohol-9'-O-β-D-glu-copyranoside ( 14 ), citrusin B ( 15 ), heteratisine ( 16 ), tanaconitine ( 17), shanzhiside methyl ester ( 18 ) and icariside B1 ( 19 ). Except compounds 4,13,16 and 17 ,the other compounds were separated from the species for the first time.
