Ultrasonic extraction device utilises high-frequency ultrasound (20/28kHz) to generate cavitation effects (microbubble implosion), which accelerates solvent penetration and dissolution of target compounds in natural materials such as plants and microorganisms. Compared with conventional methods (e.g., Soxhlet extraction or heat reflux), it offers significant advantages including reduced extraction time, lower solvent consumption, higher extraction yields, and improved energy efficiency.

1. Extraction of tea polyphenols from green tea leaves

Tea polyphenols, the primary active constituents in tea leaves, possess antioxidant and anti-inflammatory properties, making them widely applicable in industries such as cosmetics.

2. Extraction of capsaicin from chilli peppers

Capsaicin, the pungent compound in chillies, finds applications in pharmaceuticals (e.g., analgesic patches) and defensive sprays.

3. Extraction of flavonoids from ginkgo biloba leaves

Ginkgo flavonoids (e.g., quercetin and kaempferol) demonstrate cardiovascular health benefits and are commonly used in nutraceuticals and medicinal products.

4. Extraction of peppermint essential oil

Peppermint oil (primarily composed of menthol) is used in pharmaceuticals and personal care products. Traditional steam distillation methods are time-consuming and risk losing volatile components. In contrast, ultrasonic-assisted extraction improves efficiency by 5-20% compared to conventional methods while effectively preserving thermosensitive compounds (e.g., vitamins and polyphenols).
