Comparison of Effective Components Contents of Lysimachia clethroides Duby with Three Extraction Methods

摘要

[Objective] The differences in effective components contents of Lysimachia clethroides Duby were compared using three extraction methods. [Method]L. clethroides was extracted by three methods,including water extraction,water extraction-alcohol precipitation and 75% ethanol extraction,to determine the effective components of extracts,and contents of calcium,phosphorus and VCwere calculated. [Result]L. clethroides contained calcium salt,chlorine,VB1,VB2,VC and phosphate,but did not contain citrate,sulfate,carbonate or bicarbonate,acetate,lactate,VA,VDand VE; the contents of calcium and phosphorus in water extract were 150 and 3. 34 mg / g,respectively,greatly exceeding their contents in water extraction-alcohol precipitation and ethanol extraction,while the difference in VCcontent was not significant. [Conclusion] The paper provides a reference for practical application of L. clethroides as an additive.
