Abstract

The rhizome of Alisma orientale (sam.) Juz. is used in clinics for eliminating dampness, reducing edema, and promoting diuresis. This study aimed to elucidate the compounds and investigate their nuclear factor-kappa inhibitory activities in human embryonic kidney 293 cells. A new triterpene, alismaketone B (1); a new natural nortriterpene, noralisolic acid A (2); and 13 known protostane-type triterpenes were isolated from the rhizome of A. orientale. The new structures and their absolute configurations were established using HRESIMS, NMR, and electronic circular dichroism experiments. All isolated compounds were evaluated for their inhibitory activity on NF-κB. The compounds 8, 9, 10, and 14 showed moderate NF-κB inhibitory activities with their IC50 values being 64.7, 32.3, 47.3, and 37.3 μM, respectively.
