Abstract
The invention provides a method for extracting flavones from roses. Roses are naturally air-dried and ground into powder, petroleum ether is adopted to soak and degrease the powder, then the powder is naturally air-dried, the air-dried powder is put into ethanol solution with concentration being 65% to be soaked and extraction is carried out. The method is characterized in that the extraction time is 30-40 minutes; and the extraction temperature is gradually raised. By adopting the method, the extraction time can be shortened and the polysaccharide extraction rate can be improved, and the method has the characteristics of time saving and high efficiency.
Description
Technical field
The present invention relates to a kind of method of extracting flavone from Flos Rosae Rugosae, platymiscium extracts the field.
Technical background
The Flos Rosae Rugosae pattern is vivid, has medical value, often is used as a kind of ornamental plant or industrial crops.Contain abundant flavone compound in the Flos Rosae Rugosae, these compositions have various physiologic functions, can regulate the performance of body each side, improve immunity of organisms.
The extracting method of flavone mainly contains solvent extraction method, water extraction, microwave extraction method, enzymatic isolation method etc. at present.Flavone compound is because the functional group of containing is different, and its polarity also is not quite similar, and can select different solvents or the solvent of variable concentrations according to its polarity and dissolubility.But solvent extraction method is more consuming time in the prior art, and extraction ratio is not high.The present invention improves existing solvent extraction method, can shorten extraction time, improves extraction ratio, has the characteristics of time-saving and efficiency.
Summary of the invention
The purpose of this invention is to provide a kind of method of extracting flavone from Flos Rosae Rugosae, the method can shorten extraction time, improves extraction ratio, has the characteristics of time-saving and efficiency.
For realizing above purpose, a kind of method of from Flos Rosae Rugosae, extracting flavone of the present invention, with the Flos Rosae Rugosae natural air drying, be ground into powder, adopt petroleum ether to soak grease removal, then naturally dry, put into concentration and be 65% alcoholic solution and soak and extract, the Flos Rosae Rugosas pollen after the grease removal and the mass ratio of alcoholic solution are 1:15-1:20, extraction time is 30-40min, and improves gradually in 50 ℃-70 ℃ extraction temperature range and extract temperature.
Preferably, extraction time is 40min, and every 20min arranges and extracts temperature is 50 ℃, 70 ℃.
Preferably, extraction time is 30min, and every 10min arranges and extracts temperature is 50 ℃, 60 ℃, 70 ℃.
The method of extracting flavone from Flos Rosae Rugosae of the present invention is the preferred experiment parameter that obtains behind many experiments, and each step all can effectively improve the flavone extraction ratio.
In the prior art, in the certain situation of other conditions, the ul-trasonic irradiation time, along with the prolongation of extraction time, the extraction ratio of flavone was the highest when being 60-90min, because extraction time in short-term, the Flos Rosae Rugosae flavone fails fully to be dissolved in the extracting solution, and extraction ratio is relatively low, but overlong time, other chemical compounds that can be dissolved in the ethanol may also be extracted in the Flos Rosae Rugosae, cause the extraction ratio of flavone to descend.The present invention along with the variation of concentration in the solution, increases at set intervals and extracts temperature in extracting the flavone process, extraction time can be reduced to 40-60min, and extraction ratio also increases.
In the prior art, in the certain situation of other conditions, when the mass ratio of Flos Rosae Rugosas pollen and alcoholic solution was 1:30, the extraction ratio of pyrite was the highest, because when the extraction solvent that uses is less, solid-state Flos Rosae Rugosae powder can not fully be immersed in the solvent, cause the flavone in the Flos Rosae Rugosae fully not dissolve, cause extraction ratio lower, and the flavones content in the Flos Rosae Rugosae is certain, after flavone fully dissolves, increase solvent load and can't improve extraction ratio.The present invention is in extracting the flavone process, variation along with concentration in the solution, increase at set intervals and extract temperature, can increase and increase gradually the dissolubility of flavone in ethanol, be conducive to flavone and from the Flos Rosae Rugosae cell of high concentration, in the alcoholic solution of low concentration, shift, therefore can reduce the consumption of alcoholic solution.
