Eudesmane sesquiterpenoids with inhibitory effects on NO production from Artemisia princeps.

Five undescribed eudesmane methyl esters (1-5), three undescribed eudesmane-12,6-olides (6-8), and 21 known analogues (9-29) were isolated from the aerial part of Artemisia princeps Pamp. Their structures were established by detailed analysis of the NMR and HRESIMS data. The absolute configurations of 1-8 were determined based on single-crystal X-ray diffraction analysis and ECD calculations.

Three new phenylpropanoid glucosides and a new tyramine-type alkamide from .

Three new phenylpropanoid glycosides, piperpubelide (), 1-propionyl-3-hydroxy-phenyl-4-O-β-D-glucopyranoside (), and 1-propionyl-4-hydroxy-phenyl-3-O-β-D-glucopyranoside (), a new tyramine-type alkamide, puberulumine L (), together with thirteen known compounds (-) were isolated from (Benth.) Maxim. Their structures were elucidated by analysis of spectroscopic data involving NMR, IR, UV, and HRESIMS data.
