Chin J Nat Med. 2013 Jul;11(4):415-8. doi: 10.1016/S1875-5364(13)60062-X.

Abstract

Aim: To study the chemical constituents of the roots of Ilex asprella Champ. ex Benth.

Methods: Compounds 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.

Results: Four 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).

Conclusion: Compound 1 is a new triterpenoid glycoside, and compounds 3 and 4 were isolated from this plant for the first time.

Keywords: Ilex asprella; Treterpenoids; Triterpenoid glycosides.
