Triterpenes and triterpenoid saponins from the leaves of Ilex kudincha.

One new triterpene, kudinchalactone A (1), and four new triterpenoid saponins, ilekudinchosides A-D (2- 5), were isolated from the leaves of Ilex kudincha C. J. Tseng along with eight known triterpenoids. These new compounds were elucidated by spectroscopic methods including 1D and 2D NMR, HR-TOF-MS, and CD spectra. Compounds 2, 3, 12, and 13 showed antibacterial activities against Staphylococcus aureus (SA) and methicillin-resistant Staphylococcus aureus (MRSA).

Structure elucidation and NMR assignments of an unusual triterpene saponin derivative from Ilex kudincha.

One unusual triterpenoid derivative, ilekudinchoside E (1), was isolated from the leaves of Ilex kudincha. The structure was established by various spectroscopic techniques, including one- and two-dimensional NMR, HRTOFMS and CD spectra.
