摘要
目的对一年蓬的化学成分进行分离和结构鉴定。方法运用Diaion HP-20、Toyopearl HW-40、Sephadex LH-20、硅胶、制备液相等多种柱色谱技术进行分离纯化,并根据化合物的光谱数据和理化性质进行结构鉴定。结果分离得到20个化合物,分别为香草酸(1),阿魏酸(2),对羟基苯乙酮(3),二氢松柏醇(4),黑麦草内酯(5),4-羟基-3-甲氧基苯丙-8-烯-4-O-β-D-吡喃木糖基-(1→6)-β-D-吡喃葡萄糖苷(6),吲哚-3-甲醛(7),5,7-二羟基色原酮(8),焦袂康酸(9),erigeside D(10),3,5-二甲氧基-4—O-(β-D-吡喃葡萄糖基)-苯甲酸甲酯(11),二氢去氢二愈创木基醇4'-O-β-D-葡萄糖苷(12),高圣草素(13),二氢高良姜醇(14),白杨素(15),高车前素(16),金圣草素(17),环桑皮素(18),蓟黄素(19)和柚皮素(20)。结论化合物1~8、11~19为首次从该植物中分到。
OBJECTIVE To study the chemical constituents of Erigeron annuus ( L. ) Pers.. METHODS The compounds were isolated and purified by Diaion HP -20, Toyopearl HW -40, Sephadex LH -20, MCI Gel CHP -20, silica gel column chromatography, and preparative HPLC, and their structures were elucidated on the basis of spectral data and physiochemical properties. RESULTS Twenty compounds were elucidated as vanillic acid( 1 ) , ferulic acid(2), 4-hydroxyacetophenone(3 ) , dihydroconiferylalcohol (4), loliolide ( 5 ), 4-hydroxy-3-methoxyphenylprop-8-ene 4-O-/3-D-xylopyraosyl- ( 1 →6 ) -β-D-glucopyranoside ( 6 ), 1H-indole-3- carbaldehyde (7), 5,7-dihydroxychromone ( 8 ), pyromeconic acid ( 9 ), erigeside D ( 10 ), methyl syringate 4-O-β-D-glucopyranoside ( 11 ), ( 7 S, 8R) -urolignoside ( 12 ), homoeriodictyol ( 13 ), pinobaksin ( 14 ), chrysin ( 15 ), hispidulin ( 16 ), chryseriol ( 17 ), cyclomorusin(18) , cirsimaritin( 19), and naringenin(20) , respectively. CONCLUSION Compounds 1 - 8 and 11 - 19 is isolated from this plant for the first time.
