Abstract: An antibacterial natural green dye, and a method for extracting the natural green dye are provided to improve the stability of a green dye and the reproducibility of extraction. A natural green dye comprises a green dye extracted the leaves of bamboo. The natural green dye is prepared by (110) pretreating the leaves of bamboo; (120) stabilizing the pretreated leaves of bamboo; and (130, 140) extracting a green dye from the stabilized one. Preferably the pretreated leaves of bamboo is stabilized by using any one selected from a copper sulfate solution, a copper hydrochloric acid solution, a sulfate, and a copper phosphate solution. Preferably the green dye is extracted by using sodium hydroxide.
