Abstract

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.

期刊介绍： Natural Products and Bioprospecting serves as an international forum for essential research on natural products and focuses on, but is not limited to, the following aspects: Natural products: isolation and structure elucidation Natural products: synthesis Biological evaluation of biologically active natural products Bioorganic and medicinal chemistry Biosynthesis and microbiological transformation Fermentation and plant tissue cultures Bioprospecting of natural products from natural resources All research articles published in this journal have undergone rigorous peer review. In addition to original research articles, Natural Products and Bioprospecting publishes reviews and short communications, aiming to rapidly disseminate the research results of timely interest, and comprehensive reviews of emerging topics in all the areas of natural products. It is also an open access journal, which provides free access to its articles to anyone, anywhere.
