Embodiment Construction

[0029] The present invention will be further described in detail below through the specific examples, the following examples are only descriptive, not restrictive, and cannot limit the protection scope of the present invention with this.

[0030] An extraction and concentration process of total flavonoids of hawthorn, which is composed of an extraction process of total flavonoids of hawthorn and an evaporation concentration process of total flavonoids of hawthorn, the innovations of which are:

[0031] The extraction process steps of hawthorn total flavonoids are:

[0032] a. Select hawthorn and dry it in an oven. Set the temperature of the oven to 80°C, the humidity to 50%, and the drying time to 1h;

[0033] b. Grind the dried hawthorn, and take a 60-mesh sieve to filter out the hawthorn powder as the experimental material;

[0034] c. Put 10g hawthorn powder and 20 times 70% ethanol into the preheating tank, soak for 25 minutes;

[0035] d. Fill water into the water tank ...

Abstract

The invention relates to a process for extracting and concentrating total flavone in hawthorn. The process comprises a process for extracting total flavone in hawthorn and a process for evaporating and concentrating total flavone in hawthorn. The process is characterized in that the process for extracting total flavone in hawthorn and the process for evaporating and concentrating total flavone in hawthorn are respectively completed in integrated ultrasonic extraction, evaporation and concentration equipment. The process is scientific and reasonable in design, has the advantages of simplicity in operation, short extraction and concentration time, high concentration degree, uniformity in extraction, high circulation speed, good solution property, small possibility of scaling, convenience in equipment washing and repair and simplicity, and is relatively high in innovativeness.

Description

technical field [0001] The invention belongs to the field of extraction and evaporation concentration, in particular to an extraction and concentration process of hawthorn total flavonoids. Background technique [0002] Ultrasound has been widely used in the fields of food, medical and health, and home appliances since its generation, manifested in ultrasonic extraction, ultrasonic sterilization, ultrasonic filtration, ultrasonic cleaning, etc. In recent years, the application of ultrasonic technology in the extraction process of traditional Chinese medicine preparations has attracted the attention and research of scholars at home and abroad. The research content is mainly the study of ultrasonic extraction process in small-scale laboratories. [0003] In the current extraction process of phytochemical components, especially the extraction process of hawthorn total flavonoids, it is generally still in the stage of electric heating extraction, and the local temperature rises,...
