The structures of the metabolites were determined by a combination of spectroscopic analysis and chemical degradation. The aglycone of 6 has the new isoxestovanane triterpenoid carbon skeleton. Compounds 7, 8, and 11 are the first X. vanilla triterpenoid glycosides known to contain three monosaccharide subunits.}, keywords = {C-13 ASSIGNMENTS, GLYCOSIDE, H-1, NMR, SPONGE, SUGARS, TRITERPENOID, XESTOSPONGIA}, isbn = {0008-4042}, url = {://A1991GH86100003}, author = {Morris, S.
