The invention discloses a fluorescent probe for identifying cysteine and glutathione. The structure of the probe is a chemical formula: the formula is shown in the description. The preparation methodof the fluorescent probe for identifying the cysteine and the glutathione comprises the following steps: S1, performing reaction by taking 3-carboxyl-4-chlorine-7-diethylamine coumarin and 3-hydroxyl-N-(2-ethyl morpholine)benzamide as raw materials to obtain an intermediate; and S2, performing reaction by taking the intermediate and p-nitrophenol as raw materials to obtain a probe. The fluorescentprobe can identify the cysteine and the glutathione from various kinds of amino acid and some common substances, has a lysosome targeted function at the same time, can directionally detect the cysteine and the glutathione in the lysosome, has good selectivity and high sensitivity on the cysteine and the glutathione, and has a good application prospect in detection and analysis of the cysteine andthe glutathione in environments or biological samples.
