摘要:

本文主要研究了连翘中双四氢呋喃木脂素类化学成分的13C NMR和CD谱的特征。通过大孔吸附树脂、硅胶、Sephadex LH-20、反相HPLC等多种色谱手段对连翘的50%乙醇提物中的木脂素类成分进行分离纯化,并根据理化性质和波谱数据鉴定其结构,最终分离得到了7个双四氢呋喃木脂素类化合物,分别为(+)-8-hydroxyepipinoresinol-4-O-β-D-glucopyranoside(1)、(+)-8-hydroxyepipinoresinol-4′-O-β-D-glucopyranoside(2)、(+)-松脂素-4-O-β-D-葡萄糖苷(3)、(+)-表松脂素-4-O-β-D-葡萄糖苷(4)、(+)-表松脂素-4′-O-β-D-葡萄糖苷(5)、(+)-phyllrin(6)和(+)-pinoresinol(7)。对这7个双四氢呋喃木脂素类化合物的13C NMR和CD特点进行了总结。

Abstract:

The 13C NMR and CD spectral characteristics of tetrahydrofuran lignans from Forsythia suspensa had been studied.Seven lignans were isolated from the 50% EtOH extract of F.suspensa by a combination of various chromatographic techniques including column chromatography over macroporous resin,silica gel,Sephadex LH-20 and reversed-phase HPLC.Their structures were identified as (+)-8-hydroxyepipinoresinol-4-O-β-D-glucopyranoside (1),(+)-8-hydroxyepipinore-sinol-4′-O-β-D-glucopyranoside (2),(+)-pinoresinol-4-O-β-D-glucopyranoside (3),(+)-epipinoresi-nol-4-O-β-D-glucopyranoside (4),(+)-epipinoresinol-4′-O-β-D-glucopyranoside (5),(+)-phyllrin (6) and (+)-pinoresinol (7) on the basis of chemical and spectral analysis.The 13C NMR and CD characteristics of the configuration of tetrahydrofuran lignans were summarized in this paper.
