Using a medium pressure liquid chromatographic system, a new triterpene lactone named glyuranolide [3 beta, 22 alpha-dihydroxy-11-oxo-delta 12-oleanene-27 alpha-methoxy carbonyl-29-oic acid (29, 22 alpha-) lactone.] was isolated from the crude sapogenins of Glycyrrhiza uralensis Fisch. Its structure was elucidated by IR, UV, FAB-MS, and various NMR spectra (including NOE, BBD, INEPT, SR, COSY, NOESY etc.).
