Abstract

Abstract: In this phytochemical study, a novel arborinane-type triterpenoid glycoside (1 ) and three known megastigmanes (2 –4 ) were isolated from the dried roots of Cyathula officinalis K.C.Kuan. The structures of these compounds were elucidated using NMR spectroscopy. This is the first report of arborinane-type triterpenoids in the Amaranthaceae family. Among these known megastigmanes, compound 3 was isolated from the Amaranthaceae family for the first time, while compounds 2 and 4 were first reported from the Cyathula genus. The chemotaxonomic significance of these compounds is discussed. Graphical abstract: Image 1 Highlights: A novel arborinane-type triterpenoid glycoside (1 ) was isolated from Cyathula officinalis.
