Abstract

Nine novel quinone-methide triterpenoids: 20-hydroxytingenone, 20,22beta-dihydroxytingenone, 20,22beta-dihydroxy-20-epi-tingenone, 20,21alpha-dihydroxy-22-oxo-21-desoxotingenone, 20-hydroxy-22-oxotingenone, 20-hydroxy-22-oxo-20-epi-tingenone, 21alpha-hydroxy-20,22-dioxo-30(20-->21)abeo-21-desoxotingenone, 20-oxo-20,21-seco-tingen-21-oic acid and 20-oxo-21-nor-20,21-seco-tingen-22-al, were isolated from the stem bark of Glyptopetalum sclerocarpum. Their structures were determined on the basis of spectroscopic evidence.
