- Abstract
Seven triterpene saponins were isolated from Lysimachia christinae and identified as lysichriside A (1), lysichriside B (2), primulanin (3), lysikokianoside 1 (4), anagallisin C (5), ardisiacrispin A (6), and ardisicrenoside B (7). Compounds 1 and 2 are new triterpene saponins, compounds 3, 5, and 7 were isolated from this genus, and compounds 4 and 6 were isolated from this species for the first time. Their structures were elucidated by means of 1D and 2D NMR experiments.
