In our continuing effort to discover more new cytotoxic sesquiterpenoids from Solanum lyratum, one new eudesmane-type sesquiterpenoid (1, 3-keto-eudesm-9β,11-diol, named lyratol G), together with one known eudesmane-type sesquiterpenoid (2, 1β-hydroxy-1,2-dihydro-α-santonin), was obtained. The
One new eudesmane-type (1, named solajiangxin A) and two new eudesmane-related sesquiterpenoids (2-3, named solajiangxins B-C) were isolated from the whole plant of Solanum lyratum. Their structures were elucidated on the basis of integrated spectroscopic techniques. In vitro, three new
Eleven sesquiterpenoids including four new eudesmane sesquiterpenoids, solanoids A-D (1-4), and seven known compounds (5-11) were isolated from the herbs of Solanum lyratum. By analyzing the UV, MS and NMR data, the gross structures of all isolates were established. The absolute configurations of
Two new sesquiterpenoid derivatives, attributable to eudesmane-type (1-2, named septemlobin D and 11,12-O-isopropylidenesolajiangxin F), were isolated from the whole plant of Solanum septemlobum. Their structures were elucidated on the basis of integrated spectroscopic techniques, mainly HR-FAB-MS,
