Abstract: A new triterpene and three new triterpenoid glycosides were isolated from Ilex kudincha.Their chemical structures were determined by 2D NMR spectra.The whole assignment of proton and carbon NMR spectra is given for the first time.

Key words: Ilex kudincha, Aquifoliaceae, α-kudinlactone, Triterpene, Glycoside, 2D NMR
