Optimization of Ultrasonic Pretreatment and Analysis of Chlorogenic Acid in Potato Leaves

Researchers now recognize ultrasonic pretreatment as a crucial method for extracting bioactive chemicals from plant materials. This study investigates the enhancement of ultrasonic pretreatment, specifically for determining chlorogenic acid in potato leaves.

An Overview of Ultrasonic Pretreatment:

Ultrasonic pretreatment utilizes high-frequency sound waves to break cell structures and improve the desired chemical extraction from plants. Ultrasonic waves induce the formation of cavitation bubbles, which subsequently collapse, releasing high levels of heat and pressure. This phenomenon aids in cell wall disintegration and improves mass transfer efficiency.

In comparison to traditional approaches, the use of ultrasonic pretreatment has become increasingly popular because of its efficacy in enhancing extraction yields and decreasing processing time. This technology has diverse uses in industries such as medicine, food, and cosmetics.

Chlorogenic acid serves a function in potato leaves:

Chlorogenic acid is a significant polyphenolic chemical that is present in a variety of plants, including potato leaves. It belongs to the hydroxycinnamic acid family and is known for its antioxidant properties. Chlorogenic acid has shown promise in promoting health by exhibiting anti-inflammatory, anti-diabetic, and cardiovascular protective properties.
Chlorogenic acid in potato leaves aids in the plant’s defense against environmental stresses. It functions as a phytochemical barrier, safeguarding the plant against diseases and UV radiation.
