Benefits of technology

This patented process involves creating new plant material called melon seeds that have enhanced levels of flavonoids like quercetone or caffeine due to their unique structure. These materials are extracted by various methods such as liquid nitrogen coolant immersion for 3 hours at room temperature followed by filtrate drying. By doing this they provide valuable health benefits when taken through these treatments over time.

Problems solved by technology

This patented technical problem addressed in this patent relates to developing new methods for studying plant biomarkers related to various degenerations caused by oxidized stressors like nitrogen monoxytrasonicsulfonium ion(NMTS)/dihydroxynitransferase/transglutaminase complexes (DNTF)) and chemotherapy agents targeted at different stages of neuronal injury due to amputation associated with brain tissue loss. Current techniques involve collecting samples containing pure products obtained from plants grown under specific conditions over time, but current separating and purifying processes require expensive equipment and consume significant amounts of organismsolvant resources.

Abstract

The invention provides a phenethyl alcohol glycoside-containing callicarpa kochiana extractive. The main component of the attractive is phenethyl alcohol glycosides compound. The preparation method of the extractive comprises the steps of: extracting the stem leaf of callicarpa kochiana to obtain extracting solution by reflowing water or 50-75% (v/v) alcohol; and purifying the extracting solution with macroporous resin to the extractive, wherein the extractive comprises 40-55% (w/w) forsythoside A and 10-30% (w/w) verbascoside. The animal experiment shows that the extractive can strengthen or improve the learning and memory functions to normal mice and various model animals with damaged memory, and can be used for preparing the medicine for curing the senile dementia and particularly preparing the medicine for curing vascular dementia (VD).
