Abstract:
OBJECTIVE:To study the extraction rate and speciation of antivitiligo-related elements in Opercalina turperthum by water extraction and semi-bionic extraction. METHODS:Water extraction and semi-bionic extraction were respectively used. Wa-ter-soluble state and suspension state in extract of O. turperthum were separated by microporous filtering film;organic and inorgan-ic trace elements in water-soluble state were separated by macroporous resin. The contents of Cu,Zn,Fe,Ca,Mg,Mn and Sr were detected by flame atomic adsorption spectrophotometry,and speciation analysis was conducted. RESULTS:After water extrac-tion,extraction rates of 7 trace elements were 40.47%-72.49%;ratio of suspended particles was 3.69%-8.78%;ratio of organic state/inorganic state was 104.36% in water-soluble state of Sr and 3.94%-48.39% in water-soluble state of Cu,Zn,Fe,Ca,Mg, Mn. After semi-bionic extraction,except for Mn,extraction rates of trace elements were higher than water extraction,extraction rates of Cu,Zn,Fe,Ca,Mg,Sr were 77.69%-90.19%;ratio of suspended particles was 0.39%-8.57%;the ratio of organic state/inorganic state was 72.74%-180.79% in water-soluble state of elements. CONCLUSIONS:Cu,Zn,Fe,Ca,Mg,Mn and Sr in O. turperthum are dissolved easily,mainly existing in the form of inorganic state. After semi-bionic extraction,except for Mn,the dis-solution rate of other elements and the proportion of organic trace elements after dissolution increase significantly. Both dissolution and effective utilization rate of trace elements by semi-bionic extraction are higher than water extraction.
