摘要:

橙皮素A是从中药北沙参(Glehnia littoralis Fr. Schmidt ex Miquel)的正丁醇萃 取物中分离得到的一种8-O-4′-型异木脂素苷类化合物. 通过化学方法和波谱分析鉴 定了该 化合物的结构. 采用2D NMR技术对其NMR信号进行了全归属. DMSO-d6代替CD3OD作为溶剂,并利用重水交换,能准确读出偶合常数J7,8值. 

关键词: 橙皮素A, 北沙参, 2D NMR, 归属

Abstract:

A 8-O-4′neolignan glycoside, citrusin A, was isolated from the BuOH-sol uble fra ction of the ethanol extract of Glehnia littoralis. In addition to conventio nal 1D NMR methods, 2D NMR techniques (COSY, HMQC and HMBC) wer e used for the proton and carbon signals assignments. The difficulty in determining J7, 8 value s could be overcomed by using DMSO-d6 and D2O instead of CD3OD as a solvent.

Key words: citrusin A, Glehnia littoralis, 2D NMR, assignment
