摘要: Phytochemical study of the n-BuOH extract of Ilex asprella resulted in the discovery of ten new pentacyclic triterpenoid glycosides, comprising nine ursane-type glycosides (1-9) and one oleanane-type glycoside (10), along with seven known compounds (11-17). Compound 1 is the first reported 19,22-epoxy ursane triterpenoid glycoside, whereas 4 and 5 are rare examples of ursane triterpenoid glycosides containing a 28,19-lactone group. The structural characterization of these compounds was achieved using spectroscopic and chemical techniques, as well as single-crystal X-ray analysis. Compounds 7, 12, 15, and 17 exhibited moderate cytotoxic activities against H1975 and HCC827 cancer cells.
