【摘要】综合运用各种色谱分离技术对党参的水提取物进行化学成分研究,利用各种波谱技术确定化合物的结构。该研究从党参中分离得到8个单体成分,分别鉴定为:(-)-(7R,8S,7'E)-3',4-dihydroxy-3-methoxy-8,4'-oxyneoligna-7'-ene-7,9,9'-triol(1)、9-(tetrahydropyran-2-yl)-nona-trans,trans-2,8-diene-4,6-diyn-1-ol(2)、9-(tetrahydropyran-2-yl)-trans-non-8-ene-4,6-diyn-1-ol(3)、党参炔苷元(4)、党参炔苷(5)、去氢双松柏醇(6)、5-羟甲基-糠醛(7)、4,4'-dihydroxy-3,3'-dimethoxy-trans-stilbene(8)。其中,化合物1为新的木脂素类化合物,2,3为首次从党参属中分离得到。

【Abstract】A new neolignan, (−)-(7R, 8S, 7'E)-3', 4-dihydroxy-3-methoxy-8, 4'-oxyneoligna-7'-ene-7, 9, 9'-triol (1), and seven known compounds, 9-(tetrahydropyran-2-yl)-nona-trans, trans-2, 8-diene-4, 6-diyn-1-ol (2), 9-(tetrahydropyran-2-yl)-trans-non-8-ene-4, 6-diyn-1-ol (3), lobetyol (4), lobetyolin(5), dehydrodieoniferyl alcohol (6), 5-hydroxymethylfurfural (7), and 4, 4'-dihydroxy-3, 3'-dimethoxy-trans-stilbene (8), were isolated from the H2O extract of Codonopsis pilosula. The structures of 1-8 were elucidated by spectroscopic methods including NMR, HR-ESI-MS, and CD. In addition, compounds 2 and 3 were isolated from the genus Codonopsis for the first time.
