Two new triterpenoid saponins from the leaves of Ilex kudingcha.
J Asian Nat Prod Res. 2012; 14(4):308-13.JA

Abstract

Two new triterpene saponins, ilekudinchosides F (1) and G (2), along with three known saponins were isolated from the leaves of Ilex kudingcha C. J. Tseng. The new compounds were characterized as 3β,19α-dihydroxy-12α-ethoxy-urs-13(18)-ene-28,20β-lactone-3-O-[β-D-glucopyranosyl(1 → 3)]-[α-L-rhamnopyranosyl(1 → 2)]-α-L-arabinopyranoside (1) and 3β,19α-dihydroxy-12α-methoxy-urs-13(18)-ene-28,20β-lactone-3-O-[α-L-rhamnopyranosyl(1 → 2)]-α-L-arabinopyranoside (2). The new structures were elucidated by spectroscopic methods including 1D and 2D NMR, HR-TOF-MS, and CD spectrometry, and the known compounds were identified by the comparison of their NMR and HR-TOF-MS data with those reported in the literature.
