A new triterpenoid glycoside from the roots of Ilex asprella

AimTo study the chemical constituents of the roots of Ilex asprella Champ. ex Benth.MethodsCompounds were isolated by silica gel, ODS, and Sephadex LH-20 column chromatography, and their structures were elucidated on the basis of physicochemical properties and spectroscopic analysis.ResultsFour triterpenoid glycosides were isolated and identified as (3β)-19-hydroxy-28-oxours-12-en-3-yl β-D-glucopyranosiduronic acid n-butyl ester (1), ilexasoside A (2), monepaloside F (3), and ilexoside A (4).ConclusionCompound 1 is a new triterpenoid glycoside, and compounds 3 and 4 were isolated from this plant for the first time.
