Embodiment 1

[0032] The extraction steps of the present invention are as follows:

[0033] 1. Collect fresh peony leaves, wash them with water, drain the water, sprinkle sodium chloride evenly on the peony leaves according to the mass ratio of peony leaves: sodium chloride 1:0.6, and knead the peony leaves after sprinkling 10-15min, so that sodium chloride penetrates into the peony leaves;

[0034] 2. After kneading, dry the peony leaves with microwave, the microwave power is 10kw, the drying temperature is 45°C, and dry until the water content of the peony leaves is lower than 10%;

[0035] 3. After drying, freeze the peony leaves at -15°C for 8 minutes, and then at -5°C for 25 minutes;

[0036] 4. Put the frozen peony leaves directly into a heating container (reaction kettle) with a condenser and an oil-water separator, and compact them so that the peony leaves are tightly placed in the heating container. After pressing the peony leaves, add water until they are submerged Peony leaves ...

[0039] The extraction steps of the present invention are as follows:

[0040] 1. Collect fresh peony leaves, wash them with water, drain the water, sprinkle sodium chloride evenly on the peony leaves according to the mass ratio of peony leaves: sodium chloride 1:0.5, and knead the peony leaves after sprinkling 10-15min, so that sodium chloride penetrates into the peony leaves;

[0041] 2. After kneading, dry the peony leaves with microwave, the microwave power is 15kw, the drying temperature is 50°C, and the peony leaves are dried until the water content of the peony leaves is lower than 10%;

[0042] 3. After drying, freeze the peony leaves at -15°C for 10 minutes, and then at -5°C for 20 minutes;

[0043] 4. Put the frozen peony leaves directly into a heating container (reaction kettle) with a condenser and an oil-water separator, and compact them so that the peony leaves are tightly placed in the heating container. After pressing the peony leaves, add water until they are ...

Embodiment 3

[0046] The extraction steps of the present invention are as follows:

[0047] 1. Collect fresh peony leaves, wash them with water, drain the water, sprinkle sodium chloride evenly on the peony leaves according to the mass ratio of peony leaves: sodium chloride 1:0.8, and knead the peony leaves after sprinkling 10-15min, so that sodium chloride penetrates into the peony leaves;

[0048] 2. After kneading, dry the peony leaves with microwave, the microwave power is 5kw, the drying temperature is 40°C, and dry until the water content of the peony leaves is lower than 10%;

[0049] 3. After drying, freeze the peony leaves at -15°C for 5 minutes, and then at -5°C for 30 minutes;

[0050]4. Put the frozen peony leaves directly into a heating container (reaction kettle) with a condenser and an oil-water separator, and compact them so that the peony leaves are tightly placed in the heating container. After pressing the peony leaves, add water until they are submerged Peony leaves 10...

Abstract

The invention discloses an extracting method for effective components of peony leaves and obtained products. The method comprises the steps that the peony leaves are washed and then kneaded by adding salt; microwave drying is performed at 40 DEG C-50 DEG C after kneading is finished until the water content is lower than 10 percent; after drying is finished, freezing is firstly performed for 5-10 min at minus 15 DEG C and then performed for 20-30 min at minus 5 DEG C; the frozen peony leaves are put into a heating container and then compressed, heat preservation is performed for 0.5-1 h at the temperature of 50 DEG C-60 DEG C, and then heating is performed until boiling is achieved to collect distilled components, namely, peony leaf aqueous extracts. The extracting method is simple and easy to operate and efficient in cleaning, the pretreatment means of salt adding and kneading, microwave drying and low-temperature freezing is adopted, and therefore more effective components can be extracted; tests prove that the obtained peony leaf aqueous extracts have the good anti-bacterial and anti-inflammatory effects and can serve as raw materials of anti-inflammatory drugs.

Description

technical field [0001] The invention relates to a method for extracting effective components of peony leaves, in particular to a method for extracting water-soluble effective components of peony leaves and the extracted peony leaf extract, belonging to the technical field of plant effective component extraction. Background technique [0002] Peony (Latin name: Paeonia suffruticosa Andr.) is a plant of the family Ranunculaceae and the genus Paeoniae. It is a small perennial deciduous shrub. Peony has a wide range of uses. In addition to its ornamental value, its root bark can be used as medicine. Peony contains volatile oils, terpenes, hydrocarbons, flavonoids, higher fatty acids (palmitic acid, linoleic acid, linolenic acid, etc.), proteins, polyphenols, mineral elements, vitamins, etc. Arteriosclerosis, inhibition of tumor metastasis, sedation, refreshing, improving memory, regulating endocrine, improving immunity, etc., is a very good health care substance. Peony leaves...
