Abstract

Four triterpenoids named (9__β__,31__R__)‐9,25‐cyclo‐30‐propylhopan‐31‐ol (1), (3__β__)‐3‐hydroxy‐30‐propylhopan‐31‐one (2), (3__β__)‐oleanan‐3‐ol (3), and (3__β__,9__β__)‐9,25‐cycloolean‐12‐en‐3‐yl β‐D‐glucofuranoside (4), a steroid named (3__β__,9__β__,14__β__)‐14‐hydroxy‐9,19‐cyclocholan‐3‐yl β‐D‐glucopyranoside (5), and an anthraquinone named 6‐hydroxy‐5,7,8‐trimethoxy‐9,10‐dioxo‐9,10‐dihydroanthracen‐2‐yl acetate (6) have been isolated from the fruits and bark of Celtis australis (Ulmaceae), along with apigenin, quercetin, and its glucoside. Their structures were elucidated by means of chemical and spectral analysis including COSY, NOESY, and HMBC experiments.
