Abstract:
Objective: To study the effects of clarificant chitosan on contents of zinc,manganese,calcium and heavy metal lead in the water extraction liquid of chinese herbal medicines. Methods: The contents of these elements were determined by atomic absorption spectrophotometry.Results: The results indicated that the chitosan clarification could raise the transfer rate of some inorganic elements such as zinc,manganese and calcium as compared with water extraction and alcohol precipitation method,And it could also reduce the amount of heavy metal lead.Conclusion: chitosan as a clarificant is promising in the field of refining water extraction liquid of chinese herbal medicines.
