Two humulane-type sesquiterpenoids, namely (+)-alashanoid I () and (-)-alashanoid I (), were isolated as a pair of enantiomers from the peeled stems of . Their structures were elucidated by extensive spectroscopic data (1 D and 2 D NMR, UV, and IR), and the absolute configurations were resolved by X-ray diffraction and experimental and calculated ECD data analysis.
