通过研究芹菜叶色素的提取工艺及稳定性，确定其提取的较佳工艺及稳定性的条件．采用乙醇溶剂振荡萃取法，在5l0nm波长下，通过单因素试验，确定该色素的较佳提取工艺；研究了不同情况下芹菜叶色素的稳定性．结果表明：该色素较佳提取工艺为体积分数85％乙醇溶液，料液比1：10，30℃，振荡30min．该色素耐光、耐热性较差；一些食品添加剂以及Zn^2＋、Ca^2＋、Mg^2＋、Na^＋对色素稳定性基本无影响，但Sn^2＋、Fe^3＋、Cu^2＋、Al^3＋会降低色素稳定性，加工使用过程中应避免与铜、铁、铝、锡容器接触．

The extraction craft and stability of pigment from celery leaves are studied in this paper. The optimum craft conditions are determined by single-factor tests through ethanol solvent oscillation extraction method under the wavelength of 510nm. The results indicate, the optimum craft conditions are to oscillate 30min under 30℃ in the ethanol solvent of 85% volume fraction and solid/liquid ratio 1 ： 10. The pigment has low thermal stability and light resistance. The degeneration rate under the lights is faster than in dark. Some food additives and Zn2＋, Ca2＋ , Mg2＋, Na ＋ have little influence on the pigment,but Sn2＋, Fe3＋ , Cue＋, AI3＋ can reduce the stability of the pigment. Thus, Fe, AI, Cu and Sn vessels should not be utilized in the processing procedure of pigment.
