Extraction of chlorophyll from silkworm excrement and preparation of sodium copper chlorophyll

The methods of extracting chlorophyll from silkworm excrement and preparing sodium copper chlorophyll were studied.The causes of unstability for chlorophyll were analysized and the properties of sodium copper chlorophyll were described.The results obtained show that the temperature suitable for soaking silkworm excrement with acetone is 30～35℃,and concentration CuSO 4 solation is 1%.
