| Abstract: | Under the condition of weakly alkaline (pH≈8), green-pingment was extracted from fresh reed-leaf using 65% eatable alcohol.The stability of the green-pigment was studied under different conditions. It proves that the green-pigment in alkalescent media is stable to heat,light and most metalions. |
