Problems solved by technology

[0002] At present, biflavones are widely used in the field of medicine and chemical industry, and the demand is huge. In the current work of extracting natural biflavones from plants, arborvitae is mainly used as the main raw material. In the operation of extracting biflavonoids, the main materials are the leaves and branches of arborvitae. Although they can meet the needs of use, the requirements for raw materials are relatively strict, resulting in relatively high raw material costs. At the same time, there is often a lack of effective The method for improving the working efficiency and purity of the active ingredient extraction of Thuja arborvitae, so that the currently prepared biflavones tend to contain impurities, or directly lead to a large amount of waste of raw materials, which further affects the working efficiency, output and quality of the biflavone extraction operations. cost, so in response to this problem, it is urgent to develop a new method for extracting biflavonoids based on orientalis to meet the needs of practical work

Embodiment 1

[0019] Such as figure 1 Shown, a kind of preparation method of high-efficiency cypress biflavone comprises the following steps:

[0020] The first step is to prepare the extraction matrix, intercept vigorously growing leaves and semi-lignified branches of arborvitae without pests and diseases, and then dry and store the intercepted plant tissues at -10°C to prepare the extraction matrix;

[0021] The second step is to crush the extraction matrix. After the first step is completed, the temperature of the obtained extraction matrix is ​​lowered to -10°C within 10 minutes and kept warm, and then the cooled extraction matrix is ​​placed in a pulverizer for pulverization to prepare 150 A powdery extraction matrix, wherein during the crushing process, the temperature of the extraction matrix is ​​-10°C, and then the pulverized powdery extraction matrix is ​​naturally heated to -5°C and then kept warm for later use;

[0022] In the third step, impregnation, the powdered extraction m...

Embodiment 2

[0031] Such as figure 1 Shown, a kind of preparation method of high-efficiency cypress biflavone comprises the following steps:

[0032] The first step is to prepare the extraction matrix, intercept vigorously growing leaves and semi-lignified branches of arborvitae without pests and diseases, and then dry and store the intercepted plant tissues at 0°C to prepare the extraction matrix;

[0033] The second step is to crush the extraction matrix. After the first step is completed, the temperature of the obtained extraction matrix is ​​lowered to 10°C within 5 minutes and kept warm, and then the cooled extraction matrix is ​​placed in a pulverizer for pulverization to prepare a 100-mesh Powdered extraction matrix, wherein during the pulverization process, the temperature of the extraction matrix is ​​-5°C, and then the pulverized powdery extraction matrix is ​​naturally heated to 0°C and then kept warm for later use;

[0034]In the third step, impregnation, the powdered extracti...

Abstract

The invention relates to a preparation method of efficient hinokiflavone. The preparation method comprises seven steps of preparing an extraction matrix, crushing the extraction matrix, steeping, filtering, carrying out extraction, concentrating, and carrying out eluting. The preparation method is simple in process, simple and convenient to operate and high in operation efficiency; on one hand, the effective availability of platycladus orientalis can be effectively increased, and the raw material acquiring way is increased, so that the raw material cost is lowered, and the raw material source is broadened; and on the other hand, the accuracy and efficiency of the extraction of effective components of platycladus orientalis can be effectively improved, so that the working efficiency of the extraction of biflavone is improved, and the purity of biflavone is increased.
