Abstract
The six new dihydro‐β‐agarofuranoid sesquiterpenes 1–6 and three known compounds were isolated from the whole plant of Celastrus paniculatus. The structures including relative configurations were elucidated by means of spectroscopic analyses. Compounds 1–6 were evaluated for cytotoxicity against a panel of three human‐tumor cell lines.
