Abstract

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
