Abstract
[Objective] To compare different extracting liquids on the extraction efficiency of chlorophyll in Euonymus japonicus,and explore the chlorophyll stability.[Method] Euonymus japonicus was used as the investigate object.The effects of three different extracting liquids,namly,95% ethanol,80% acetone and 95% acetone/ethanol mixed liquor(V∶V=1∶2) on the extraction efficiency of chlorophyll in Euonymus japonicus and the effects of light,pH value,heat,oxidant,heavy metal ions and ultraviolet light on its chlorophyll stability were studied.[Result] The results showed that 95% acetone/ethanol mixed liquor(V∶V=1∶2) was the best extracting liquid,and the chlorophyll of Euonymus japonicus had a poor photostability.It was relatively stable in the neutral condition,with a certain degree of heat resistance and anti-oxidant capacity.The copper ions can increase the stability of chlorophyll,while other heavy metal ions reduced the stability of chlorophyll.Ultraviolet light can reduce the stability of chlorophyll.[Conclusion] 95% acetone/ethanol mixed liquor(V∶V=1∶2) has the best extraction efficiency of chlorophyll.The extracting liquid should keep in dark,neutral condition without heavy metal ions.
