摘要:

利用大孔树脂、MCI柱色谱、制备液相等对续断化学成分进行研究,通过NMR、HR-ESI-MS等波谱方法鉴定分离得到的化合物结构。从续断药材中分离得到13个化合物,分别鉴定为5个三萜皂苷:川续断皂苷Ⅵ(1)、威严仙皂苷A(2)、续断皂苷A(3)、3-O-(2-O-乙酰基)-α-L-吡喃阿拉伯糖常春藤皂苷元-28-O-β-D-吡喃葡萄糖-(1→6)-β-D-吡喃葡萄糖酯苷(4)、3-O-(4-O-乙酰基)-α-L-吡喃阿拉伯糖常春藤皂苷元-28-O-β-D-吡喃葡萄糖-(1→6)-β-D-吡喃葡萄糖酯苷(5),6个环烯醚萜苷:马钱苷酸(6)、马钱子苷(7)、当药苷(8)、续断苷A(9)、续断苷B(10)、林生续断苷I(11),以及2个其他类成分:5-羟甲基-2-呋喃甲醛(12)、α-亚麻酸(13),其中化合物4、12、13为首次从续断药材中分离得到,也是首次从川续断属植物中分离得到。该研究进一步丰富了续断药材化学成分组成,对于建立以质量标志物为药材优劣评价依据的续断药材质量标准提供了物质基础,同时为进一步阐释续断“发汗”加工前后化学成分及其含量的变化、化学成分转化机制研究提供了更丰富的化学物质基础。

Abstract:

The chemical composition of Radix Dipsaci was separated by D101 macroporous adsorption resin, MCI column chromatography, and preparative high-performance liquid chromatography, and the structures of the isolates were identified based on NMR, HR-ESI-MS, and other spectral methods. Thirteen compounds were isolated and obtained from the 70% ethanol extract of Radix Dipsaci, including five triterpenoid saponins: asperosaponin Ⅵ (1), cauloside A (2), dipsacus saponin A (3), 3-O-(2-O-acetyl)-α-L-arabinopyranosyl-hederagenin-28-O-β-D-glucopyranosyl-(1→6)-β-D-glucopyranoside(4),3-O-(4-O-acetyl)-α-L-arabinopyranosyl-hederagenin-28-O-β-D-glucopyranosyl-(1→6)-β-D-glucopyranoside (5), six iridoid glycosides: loganic acid (6) loganin (7), sweroside (8), dipsanoside A (9), dipsanoside B (10), sylvestroside I (11) and two other compounds: 5-hydroxymethyl-2-furfural (12) and α-linolenic acid (13), in which compounds 4, 12, 13 were isolated from the genus of Dipsacus Linn. for the first time. The chemical composition of Radix Dipsaci was further enriched in this study that provides the material basis for establishing quality standards for Radix Dipsaci based on Q-markers as the basis for evaluating the quality of Chinese materia medica. This further provides the chemical material basis for further explaining the chemical composition and content changes before and after the processing of “sweating” and the research of the chemical composition transformation mechanism of Radix Dipsaci.

Key words: Radix Dipsaci, chemical composition, identification, triterpenoid saponins, iridoid glycosides
