Abstract

OCR 10KL (08 / 07 / 2569) This invention concerns a process for converting mitragynine into 7-hydroxymitragynine. Genine from kratom leaves was extracted using liquid-phase plasma technology with an advanced oxidation process. Including by-product chemical substances from drug reactions and other processes. This occurs during plasma formation, where it reacts with the mitragynine structure to form 7-. 7-hydroxymitragynine exhibits beneficial pharmacological effects. It has been improved, becoming a more effective painkiller with a lower risk of addiction than morphine, due to the processing methods. The conversion of mitragynine to 7-hydroxymitragynine from kratom leaves was performed using plasma technology. This liquid phase has a simple process, is environmentally friendly, and can be easily operated. It does not require expert intervention, and is beneficial in medical and pharmaceutical fields. It can also be applied in the functional food industry, as well as other related fields.
