Abstract: Objective: This paper presents to study on the best extraction technology of chlorogenic acid in maize (Zea mays L.) leaves. Methods: The content of chlorogenic acid was determined by an ultraviolet- visible spectrophotometric method. The ultrasonic-assisted extraction of chlorogenic acid in maize leaves was optimized by a single factor test and an orthogonal experiment. Results: Chlorogenic acid extraction rate in maize leaves was 2.153%; the optimal extraction conditions were as follows: ultrasonic irradiation time was 100 min, volume fraction of ethanol was 70%, ultrasonic power was 80 W, liquid and material ratio (mass:volume) was 1:20, respectively. Conclusion: Chlorogenic acid content in maize leaves is high, and can be used as one of the sources of chlorogenic acid.
