TH22589Y - The process of extracting substances from kratom leaves using ultrasonic waves or microwaves. - Google Patents

Abstract

The extraction process from kratom leaves using ultrasonic or microwave waves involves extraction with an appropriate ratio of water and ethanol, followed by the use of ultrasonic or microwave waves at suitable intensity and duration. The extract is then filtered, and the concentration is increased using a vacuum evaporator. This method aims to develop extraction techniques for kratom leaves to obtain the alkaloids, phenolic compounds, and tannins, the main active compounds, for medical applications, as ingredients in pharmaceuticals, cosmetics, and health products.

Claims (8)

1. The process of extracting substances from kratom leaves using ultrasonic or microwave waves consists of: a. Preparing kratom powder: Wash and air-dry kratom leaves, then dry them in an oven at 50°C for 24 hours. Grind into a fine powder and pass through a 10-20 mesh sieve. b. Extraction process: 1) Add a solvent to the kratom powder. 2) Extraction method: 2.1) Ultrasonic wave extraction: Immerse the ultrasonic probe in the center of the container in the mixture from step 1 (water-to-ethanol ratio). Use an extraction intensity of 40-80 amps. 2.2) Microwave extraction: Use a microwave-based microwave with adjustable wattage (450-900 watts). 3) Filtration: Filter the extract. The remaining residue is then subjected to two more extraction steps to ensure complete extraction. Combine the extracted substances and evaporate them using a vacuum rotary distillation system. 2. The method for extracting substances from kratom leaves using ultrasonic or microwave waves, as per claim 1, involves adding a solvent to kratom leaf powder at a ratio of 1:20. 3. Extraction method from kratom leaves using ultrasonic or microwave waves, as per patent 1 or 2, where the solvent can be selected from water or ethanol, or the optimal water-to-ethanol ratio is 1-2:1-2, mixed thoroughly. 4. A method for extracting substances from kratom leaves using ultrasonic or microwave waves, as per any one of claims 1 to 3, where the extraction can be selected using either ultrasonic or microwave waves. 5. The method for extracting substances from kratom leaves using ultrasonic waves, according to patent 4, where the optimal ratio between water and ethanol is 2:1. 6. The extraction process from kratom leaves using ultrasonic waves, as per patent 4 or 5, allows for either continuous or paused extraction. The optimal method involves 15 pauses, each extracting for 1 minute and pausing for 15-30 minutes. 7. The method for extracting substances from kratom leaves using microwave radiation, according to claim 4, where the optimal ratio between water and ethanol is 1:1. 8. The extraction process from kratom leaves using ultrasonic waves, as per patent 4 or 7, allows for either continuous or paused extraction. The optimal method involves 20 paused extraction cycles, each lasting 1 minute with a 1-minute pause, for a total duration of 20-40 minutes.
