摘要：

The structure of 20-hydroxytingenone was revised to be 20-hydroxy-20-epi-tingenone, based on the results from extensive NMR studies (COSY, ROESY, HMQC, HMBC and selective INEPT experiments). Examination of the HMQC and HMBC spectra of 22beta-hydroxytingenone led to the revision of its previous C-13 NMR assignments.
