Abstract
The invention discloses a method for extracting general flavone from soybean leaves. The method comprises the following steps: extracting the soybean leaves by virtue of an ethanol solution to obtain an extracting solution, putting the extracting solution on a column by virtue of macroporous resin absorption, eluting to obtain an eluent, collecting the eluent, concentrating the eluent, and drying, thereby obtaining the product. The method disclosed by the invention has the beneficial effects that 1, the ethanol solution serves as the extracting solution and the eluent and is free of pollution to the environment and products, and green, and the product quality is high; 2, the steps are simple, the operating time is short, the investment is low, and the cost is low; and 3, the content of the general flavone in the obtained extract is high, the yield is high, and the economic benefits are good.
Description
Technical field
The present invention relates to the preparation method of a Plant Extracts, be specifically related to a kind of method extracting total flavones from Soybean Leaves.
Background technology
Total flavones is a kind of important active ingredient contained in Soybean Leaves, has protection cardiovascular system, blood pressure lowering and antiinflammatory, antioxidation, can be used for disease such as treatment hypertension, diabetes etc.In the past is mostly that Bian methanol extraction or water extraction obtain extractive of general flavone from Soybean Leaves, on this basis can also in conjunction with additional physical field strengthening effects such as ultrasonic, microwaves, the shortcomings such as but these extracting method often exist, and yield is low, energy consumption is high, operation is many, toxicity greatly, is easily gone mouldy, mostly containing plurality of impurities in the total flavones crude extract obtained, cause its quality to decline, reduce its medical value.Therefore adopting effective extracting method, extract highly purified extractive of general flavone from Soybean Leaves, is the main direction of studying of this area.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of method extracting total flavones from Soybean Leaves, has the advantage of science environmental protection, extract quality better.
In order to solve the problems of the technologies described above, the present invention by the following technical solutions:
From Soybean Leaves, extract a method for total flavones, be by Soybean Leaves after alcoholic solution extracts, with macroporous resin adsorption by extracting solution through upper prop, eluting, collection eluent, eluent is concentrated, obtain product after drying.
In technique scheme:
Described Soybean Leaves volumetric concentration is the alcoholic solution extraction of 30% ~ 80%, and altogether extract three times, the mass ratio of each Soybean Leaves and alcoholic solution is 1:3 ~ 10, extracts 0.1 ~ 1 hour at every turn; Further, the concentration of alcoholic solution is preferably 55%, and the mass ratio of Soybean Leaves and alcoholic solution is preferably 1:5, and each time of extracting is preferably 0.5 hour.
Described macroporous resin is any one in AB-8, HZ818, HPD-100 and D101;
The flow velocity that described extracting solution flows through macroporous resin is 1 ~ 3mL/min, is preferably 2mL/min;
During described eluting, selective body volume concentrations is the alcoholic solution of 50% ~ 95% is eluant, and elution flow rate is 1 ~ 4mL/min; Further, the concentration of alcoholic solution is preferably 75%, and elution flow rate is preferably 2.5mL/min.
The invention has the beneficial effects as follows:
1, the present invention take alcoholic solution as extracting solution and eluent, to environment and product pollution-free, environmental protection, product quality is high;
2, step of the present invention is simple, and the operating time is short, small investment, and cost is low;
3, the extractive of general flavone of the present invention's acquisition, general flavone content can reach more than 40%, and yield is high, good in economic efficiency.
