摘要
目的研究黑龙江省榛(平榛)Corylusheterophylla的鞣质成分。方法利用大孔树脂柱色谱分离纯化技术反复分离纯化,通过1H-NMR、13C-NMR、FAB-MS、1H-1HCOSY等光谱手段及化学方法对得到的单体成分进行结构鉴定。结果从该植物叶中分离得到3个鞣质成分榛叶鞣质D(Ⅰ)、刺梨素A(Ⅱ)、玫瑰素F(Ⅲ)。结论榛叶鞣质D(Ⅰ)为一新的二聚体鞣质成分。
Objective To study tannins of Corylus heterophylla from Heilongjiang Province. Methods The constituents were separated and purified repeatedly by macroporons resin chromatography methods and their structures were identified by 1H-NMR, 13C-NMR, FAB-MS, and 1H-1HCOSY spectra, and chemical methods as well. Results Three tannins were obtained from C. heterophylla. They were heterophylliin D (Ⅰ), roxbin A ( Ⅱ ), and rugosin F ( Ⅲ ). Conclusion Heterophylliin D ( Ⅰ ) is isolated from the extract of C. heterophylla leaves as a new dimmer tannin firstly.
