Abstract
A new disaccharide glycoside, franchoside A (1), and 17 known compounds were isolated from the tubers of Arisaema franchetianum Engler. The chemical structure of the previously undescribed compound 1 was elucidated on the basis of detailed spectroscopic analyses. Compounds 1, 2, 6, 10, 14 and 18 showed significant cytotoxic activities at varying IC50 values in the range of 4.0–10.6 μM against five cancer cell lines. Compounds 8, 10, 13 and 17 (10 μM) exhibited moderate anti-inflammatory activities by inhibiting the NF-κB signaling pathway and the release of NO from RAW264.7 macrophages induced by lipopolysaccharide (LPS), while compounds 1, 9, 14, 15 and 16 showed weak anti-inflammatory activities.
