From the aerial part of Laggera alata, a novel eremophilanoid (1) as well as two new eudesmanoids (2-3) were isolated. Their structures were elucidated by 2D-NMR technique and X-ray diffraction studies. The cytotox...From the aerial part of Laggera alata, a novel eremophilanoid (1) as well as two new eudesmanoids (2-3) were isolated.

Two new eremophilanolides, tsoongianolide E and F, were isolated from Senecio tsoongianus. Their structures were elucidated on the basis of NMR and MS spectra. Both of these two compounds showed in vitro cytotoxicity ...Two new eremophilanolides, tsoongianolide E and F, were isolated from Senecio tsoongianus. Their structures were elucidated on the basis of NMR and MS spectra. Both of these two compounds showed in vitro cytotoxicity to cultured KB and A-549 cancer cell lines.展开更多
