title: Two new eudesmane-type sesquiterpenoids from Olanum lyratum.
abstract: Two new eudesmane-type sesquiterpenoids, lyratol A-B (1 and 2), were isolated from the whole plant of Olanum lyratum Thunb and their structures were elucidated by extensive spectroscopic analyses. In addition, two new compounds were found to show significant cytotoxicity against selected cancer cells in vitro, including P-388 and HT-29.
