Abstract

Abstract: Various NMR spectra (including NOE, SD, BB, INEPT, SR, COSY, and NOESY etc.) were used in the study and identification of the chemical structure of a new glycyrrizic triterpenoid lactone which was extracted from Glycyrrhiza uralensis Fisch collected in Inner Mongolia. This new component was named Glyuranolide (3,22-dihydroxy-11-oxo-12-oleanene-14-methoxycarbonyl-29-dioic acid-22-lactone).

Key words: Glycyrriza uralensis Fisch, Glycyrrizic triterpenoid lacton, Glyuranolide, COSY (Correlated 2D spectroscopy), NOESY (Nuclear Overhauser effect spectroscopy), INEPT (Insensitive nuclei enhancement of polarization transfer), ¹³C-NMR, NOE
