    Phytoecdysones from the Roots of Achyranthes japonica Nakai and their Anti-atopy Activity[Reference: WebLink]
    The roots of Achyranthes japonica Nakai were extracted with 100% aqueous and concentrated subfraction was separated with ultra-performance liquid chromatography-based activity profiling.
    METHODS AND RESULTS:
    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.
    CONCLUSIONS:
    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.

    High performance liquid chromatography used for quality control of Achyranthis Radix[Pubmed: 22941488]
    Abstract To establish a standard of quality control and to identify reliable Achyranthis Radix, three phytoecdysones including ecdysterone (1), 25R-inokosterone (2) and 25S-inokosterone (3) were determined by quantitative HPLC/UV analysis. Three phytoecdysones were separated with an YMC J'sphere ODS C(18) column (250 mm × 4.6 mm, 4 μm) by isocratic elution using 0.1% formic acid in water and acetonitrile (85:15, v/v%) as the mobile phase. The flow rate was 1.0 mL/min and the UV detector wavelength was set at 245 nm. The standards were quantified by HPLC/UV from Achyranthes bidentata Blume and Achyranthes japonica Nakai, as well as Cyathula capitata Moq. and Cyathula officinalis Kuan, which are of a different genus but are comparative herbs. The method was successfully used in the analysis of Achyranthis Radix of different geographical origin or genera with relatively simple conditions and procedures, and the assay results were satisfactory for linearity, recovery, precision, accuracy, stability and robustness. The HPLC analytical method for pattern recognition analysis was validated by repeated analysis of eighteen A. bidentata Blume samples and ten A. japonica Nakai samples. The results indicate that the established HPLC/UV method is suitable for quantitation and pattern recognition analyses for quality evaluation of Achyranthis Radix.
