Die Struktur einiger Triterpensaponine ausAnagallis arvensis

Abstract
5 new triterpene saponines, named anagalloside A, B, C, and desglucoanagalloside A and B, were isolated from the herb of Anagallis arvensis L. (Primulaceae). The structures of the saponines were elucidated by 1H-, 13C-NMR spectroscopy, FAB-MS, and the methylating and combined methylating-ethylating analysis methods.
