This research was completed by a research scholar at Gansu Radio and Television University to discuss the optimization of ultrasonic-microwave synergistic extraction of chlorogenic acid in peach blossoms. It was published in the important journal .

Exploring the best extraction process of chlorogenic acid in peach blossom under ultrasonic-microwave synergy. Methods: Single factor test and orthogonal test method were used to optimize the optimal process for extracting chlorogenic acid from peach blossom under ultrasonic-microwave synergy. Results: The optimal extraction conditions for chlorogenic acid in peach blossom were: microwave irradiation power 300 W, ratio of material to liquid 1:25, ethanol volume fraction 70%, microwave irradiation time 60 min. Conclusion: Peach flower has rich chlorogenic acid content, and the ultrasonic-microwave synergistic extraction process is simple, easy to operate and high in extraction efficiency.

Accurately weigh 1.00 g Peach flower samples, soak for 30 min according to a certain ratio of material to liquid (1:25) and ethanol (70%). After ultrasonic-microwave synergistic radiation for a certain period of time, leaching and filtration; the slag is further leached once under the same conditions, and the filtrate is combined twice, and the filtrate is concentrated and dried under reduced pressure at 60 ° C to obtain crude chlorogenic acid extract. . The crude chlorogenic acid extract was dissolved in 70% ethanol and made up to 100 mL to obtain a chlorogenic acid sample solution.
