Abstract: The extraction technique of chlorophyll from zingiber leaves was studied,and the sodium copper chlorophyllin was prepared and its stabilities were analyzed tentatively. The results showed that the optimal extraction of chlorophyll conditions are determined as follows: using the mixture of acetone and 95﹪ alcohol with 2:1 ratio as extraction solvent,ratio of material to solvent 1:30,extraction temperature 60℃ and extraction time 5 h. The product of sodium copper chlorophyllin prepared according to the technics of saponifyication at first and then copper substitution shows some acid stability and thermal stability below 90℃.

Key words: Zingiber officinale-leaves, chlorophyll, extraction, sodium copper chlorophyllin, preparation
