Abstract
Four new eremophilane-type sesquiterpenes, culcitiolides A-D, were isolated from the stem of Senecio culcitioides Sch. Bip (Asteraceae). Their structures were established by detailed 2D NMR spectroscopic and single-crystal X-ray experiments. These compounds were assessed for inhibitory activity against nuclear factor κB (NF-κB). Culcitiolides C and D at 20 μM showed 97 and 100% inhibition of NF-κB activity, respectively.

Abstract
Biological process-free ("Bio-free") treatment of swine wastewater (pH 8.5 or above) for the removal of nitrogen and phosphorus was examined. In this study centrifugal separation of solids and liquids was followed by iron electrolysis, which enables removal of nitrogen and phosphorus when iron is set as the cathode and anode, respectively. The manner in which the treatment efficiency varies according to the current ratio of iron anode to iron cathode (Rac) was investigated. Nitrogen was removed to a level below 60 mg l(-1) in a 3-h treatment when Rac was above 75% and phosphorus was removed to a level below 8 mg l(-1) in the same period, irrespective of Rac. Nitrogen removal efficiency was 60 kWh kg-N(-1) , which is 6 times higher than that of the same electrolytic treatment when used after aerobic biological treatment ("Post-bio").

Abstract
Microbiol biotransformation of shiromodiol diacetate from Neolitsea serisea koids, and of myli-4(15)-en-9-one and myliol from the liverwort Mylia taylorii, were carried out with Aspergillus niger IFO 4407. A. niger hydroxylated the allyl position (C-2) of shiromodiol diacetate, and one of the geminal dimethyl groups of myli-4(15)-en-9-one and myliol regioselectively. The structures of these transformants were elucidated by spectral analysis and confirmed by X-ray analysis.
