Embodiment 1
[0210] Embodiment 1 of the present invention: Japonica japonicus extraction method, dry japonicus japonicus is cut into the segment of 2cm, selects distilled water as extraction solvent, japonicus japonicus is added in the extraction solvent and soaked for 0.5h, then carries out reflux extraction; Extraction temperature is 75°C, the number of extractions is 2 times, each extraction time is 1 hour, the solid-liquid ratio of the first reflux extraction is 1:15, and the solid-liquid ratio of the second reflux extraction is 1:10; After filtering, the filtrates are combined; the filtrate is then concentrated under reduced pressure, and the concentrated solution is vacuum microwave dried to obtain the Japonica Flos Japonica extract.
Embodiment 2
[0211] Embodiment 2 of the present invention: Japonica japonicus extraction method, dry japonicus japonicus is cut into the segment of 1cm, selects distilled water as extraction solvent, japonicus japonicus is added in the extraction solvent and soaked for 0.5h, then carries out reflux extraction; Extraction temperature is 95°C, the number of extractions is 2 times, each extraction time is 1.5 hours, the solid-liquid ratio of the first reflux extraction is 1:13, and the solid-liquid ratio of the second reflux extraction is 1:10; After filtering, the filtrates are combined; the filtrate is then concentrated under reduced pressure, and the concentrated solution is freeze-dried to obtain the Jasmine Japonica extract.
Embodiment 3
[0212] Embodiment 3 of the present invention: the method for extracting the japonicum japonicus, cutting the dried japonicus japonicus into 3cm sections, using ethanol with a mass percentage of 70% as the extraction solvent, adding the japonicus japonicus to the extraction solvent and soaking for 0.5h, and then carrying out Reflux extraction, the temperature of reflux extraction is 80°C, the number of extractions is 2 times, each extraction time is 2 hours, the ratio of solid to liquid for the first reflux extraction is 1:15, and the ratio of solid to liquid for the second reflux extraction is 1 : 10; after the extract is filtered, the filtrate is combined; then the filtrate is concentrated under reduced pressure, and the concentrated solution is vacuum-dried to obtain the Flos Japonica extract.
