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.

Abstract

The invention discloses a wild honeysuckle flower extracting method. The method is characterized by cutting dry wild honeysuckle flowers to segments with the dimension being about 2cm, adding the segments to an extraction solvent to be impregnated and then carrying out reflux extraction; merging filtrates after filtering the extracts; and then carrying out vacuum concentration on the filtrates and drying the concentrated solution, thus obtaining the wild honeysuckle flower extract, wherein the liquid-material ratio of the wild honeysuckle flowers to the extraction solvent is 1:(10-15), the reflux extraction temperature is 55-95 DEG C, the extraction frequency is 2-3 times and each extraction lasts for 0.5-2 hours. The method has the beneficial effects that preference is given to the technological parameters of water extraction and alcohol extraction, thus improving the yield of extracts extracted from the wild honeysuckle flowers and increasing the content of chlorogenic acids in the extracts; the technological conditions are simple, the method is easy to realize industrialization, the production quality is easy to control and the cost is low; and the method is simple and is good in using effect.

Description

technical field [0001] The invention relates to an extraction process, in particular to an extraction method of Flos Japonica. Background technique [0002] Mountain silver flower is the dry flower bud of Lonicera Flos Lonicerae Confusae in the family Caprifoliaceae. It is a commonly used medicine in traditional Chinese medicine. Thousands of years of traditional experience as well as modern pharmacological experiments and clinical applications have proved that the mountain silver flower has a strong antibacterial effect and a good therapeutic effect on various germs. [0003] The previous pharmacopoeia believed that the "nature, flavor and meridian distribution", "function and indications" and "usage and dosage" of mountain silver flower and honeysuckle are exactly the same. In this regard, relevant experts believe that "the two kinds of Yinhua can be substituted for each other in clinical application" and "the national "Pharmacopia" treats the two kinds of Yinhua equally,...
