  • Title: Preparative isolation and purification of sinomenine from Sinomenium acutum by centrifugal partition chromatography.
    Author: Cheong JH, Kim CY, Kim J.
    Journal: J Sep Sci; 2007 Aug; 30(13):2105-8. PubMed ID: 17654620.
    Abstract:
    Preparative centrifugal partition chromatography (CPC) was successfully carried out for the separation of sinomenine from the methanolic extract of Sinomenium acutum stems and rhizomes. The optimum two-phase solvent system of CPC was composed of n-hexane/ethyl acetate/methanol/water at a volume ratio of 1:6:2:8 (v/v/v/v) with 0.1% triethylamine (TEA). Preparative CPC yielded 44.3 mg of sinomenine from 400 mg of MeOH extract with a purity of 96.9%.
