The extraction and isolation of xanthorrhizol from its crude essential oil. The designated peak (xanthorrhizol) is the most abundance component, which accounted for 46.3% of the total component in the extracted essential oil of C. xanthorrhizza (A). Xanthorrhizol was detected via chromogenic reagent spray (0.5% vanillin/sulfuric acid) and UV (254 nm) visualization in TLC profile as compare to the authentic reference substance (B and C). Final isolation process produced compound 1 at 100% abundance (D) and the NMR spectral identified the compound 1 as xanthorrhizol (E).
