Problems solved by technology

Although there are some techniques for extracting flavonoids from hawthorn leaves at present, for example (Research on Extracting Total Flavonoids from Hawthorn Leaves by Polymerase Method, Food Industry Science and Technology 2002) discloses a process for enzymatic separation and extraction of total flavonoids from hawthorn leaves. The method needs to use enzyme preparation, the cost is high, and the purity of the product is low

Embodiment 1

[0017] The extraction process of the total flavonoids of Hawthorn leaves comprises the following steps:

[0018] Step 1) Select fresh hawthorn leaves, soak them in 5wt% sucrose solution for 30 minutes, take out the hawthorn leaves, and place them in a cool and ventilated place to dry;

[0019] Step 2) Crush the material obtained in step 1) into powder, spread it into a flat layer with a thickness of 3mm, and then irradiate it under ultraviolet light for 30 minutes, and the ultraviolet intensity is 2500mW / cm 2 ;

[0020] Step 3) The material obtained in step 2) was reflux extracted three times with ethanol with a volume fraction of 75%, each time for 30 minutes, the ratio of solid to liquid was 1g:15ml, combined the extracts, filtered, and collected the filtrate;

[0021] Step 4) Add 0.8wt% flocculant to the filtrate of step 3), stir evenly, then let it stand for 40 minutes, filter to remove the precipitate, and collect the supernatant;

[0022] Step 5) Concentrate the supern...

Embodiment 2

[0026] Take the embodiment 1 process as an example to detect the impact of each parameter and condition on the extraction efficiency:

[0027] Groups: control group 1, control group 2, embodiment 1 group;

[0028] Control group 1: do not use sucrose soaking and ultraviolet irradiation, other is the same as embodiment 1;

[0029] Control group 2: treated with activated carbon instead of flocculant, and the others are the same as in Example 1.

[0030] The determination of total flavonoids in the sediment is shown in Table 1:

Abstract

The invention belongs to the technical field of plant extraction and discloses a Chinese hawthorn leaf total flavone extracting process. The Chinese hawthorn leaf total flavone extracting process comprises the steps of cane sugar soaking, ultraviolet irradiation, flocculation and impurity removing, alcohol extraction, extraction, drying and the like. The process is simple, feasible, low in cost and high in product purity.

Description

technical field [0001] The invention belongs to the technical field of plant extraction, and in particular relates to an extraction process of total flavonoids from hawthorn leaves. Background technique [0002] Hawthorn leaves, the name of traditional Chinese medicine. Rosaceae Rosaceae or Hawthorn Grataegus pinnati fida Dried leaves of Bge. Harvest in summer and autumn and dry. Distributed in Northeast and North China. It has the effects of promoting blood circulation and removing blood stasis, regulating qi and dredging channels, reducing turbidity and reducing fat. For qi stagnation and blood stasis, chest obstruction and heartache, chest tightness and suffocation, palpitation and forgetfulness, dizziness and tinnitus, hyperlipidemia. Hawthorn flavonoids are medicinal ingredients extracted from hawthorn leaves, in the form of brown-red powder, and the plant source is the ripe fruit of the Rosaceae plant hawthorn. It is produced in most parts of northern my country...
