- The roots of Achyranthes japonica Nakai were extracted with 100% aqueous and concentrated subfraction was separated with ultra-performance liquid chromatography-based activity profiling. Three compounds were isolated from the subfraction 5 through the repeated prep- high performance liquid chromatography column chromatography. According to the results of physico-chemical and spectroscopic data including NMR and MS, the chemical structures of the compounds were determined as ecdysterone (1), 25S-inokosterone (2), and 25R-inokosterone (3). Three phytoecdysones were showed weak inhibitory activity for thymus and activation-regulated chemokine expression levels in tumor necrosis factor (TNF)-α plus IFN-γ induced HaCaT cells, respectively. However, those compounds 1-3 were exhibited the most potent inhibition (80？95% at 200 μg/mL) against TNF-α expression levels in A23187 plus phorbol-myrisrate acetate-induced RBL-2H3 cells. As result, 100% aqueous extract of A. japonica has an excellent anti-atopy activity. It could be used to a large range of functional anti-atopy cosmetics.
