Improving on technique of preparing sodium copper chlorophyllin from silkworm faeces
Using silkworm faeces as material,the traditional technique to prepare sodium copper chlorophyllin was improved.Chlorophyll was reacted with copper sulphate when it was being extracted.Chlorophyll,which is not endurable with heat and light,was transformed to copper chlorophyll.Comparing the two methods,the middle product was more stable,the quality and the yield of product were higher than traditional method.Besides,the reasons of the difference were discussed primarily.Other unsteady medicament from plants could be extracted according this way.
