Problems solved by technology

The present invention first aims at the problems of low active components of raw materials obtained by different drying methods and low extraction process efficiency. Fresh camellias and leaves are used as raw materials, and crushing extraction technology is used to achieve sufficient and rapid extraction while retaining active substances as much as possible; at the same time, using a certain Concentrated ethanol aqueous solution is the extraction solvent, which has the effect of sterilizing and inhibiting enzymes, so it can be regarded as a green chemical preservation treatment, with less solvent consumption, suitable for large quantities of long-term storage

Embodiment 1

[0032] Get freshly picked camellias, wash with clear water, drain and cut into shreds to obtain fresh filaments. The moisture content measured by the oven method (105° C.) is 87.2%. Get 25g of filigree and put it into a blade-type crushing device, add 100g of ethanol aqueous solution with a volume fraction of 60%, turn on the device, and crush at a speed of 8000 rpm for 1 minute to obtain a flower particle dispersion. The resulting feed liquid was transferred to a beaker, and 100 g of ethanol aqueous solution with a volume fraction of 60% was added, and ultrasonically extracted at 50° C. with a power of 420 W for 1.5 hours. After the extraction was completed, the clarified filtrate and filter residue were obtained by suction filtration under reduced pressure. The filter residue was collected, and then 200 g of ethanol aqueous solution with a volume fraction of 60% was added. Ultrasonic extraction was performed at 50°C with a power of 420W for 1.5 hours. Filtrate under reduced ...

Embodiment 2

[0034] Get freshly picked camellia leaves, wash with clear water, drain and cut into shreds to obtain fresh shredded leaves. The moisture content measured by the oven method (105° C.) is 52.2%. Get 30g shredded leaves and put them into the blade-type crushing equipment, add 120g volume fraction of 60% ethanol aqueous solution, turn on the equipment, crush for 5 minutes at a speed of 8000 rpm, and obtain the fresh leaf particle dispersion. The resulting feed liquid was transferred to a beaker, and 120 g of ethanol aqueous solution with a volume fraction of 60% was added, and ultrasonically extracted at 50° C. with a power of 420 W for 1.5 hours. After the extraction was completed, the clarified filtrate and filter residue were obtained by suction filtration under reduced pressure. The filter residue was collected, and then 240 g of 60% ethanol aqueous solution was added, and ultrasonic extraction was performed at 50° C. with a power of 420 W for 1.5 hours. Filtrate under reduce...

Embodiment 3

[0036] Get 47.1g of the same fresh filaments as in Example 1, and prepare the flower particle dispersion with the same crushing condition; the weight of the 60% ethanol aqueous solution added in the crushing process is 188.4g.

[0037] Get 12.9g of fresh shredded leaves identical to Example 2, and prepare fresh leaf particle dispersions with the same crushing conditions. The weight of the 60% ethanol aqueous solution added during the crushing process was 51.6 g.

[0038]The above two dispersions were combined, and 240 g of ethanol aqueous solution with a volume fraction of 60% was added, and ultrasonically extracted at 50° C. with a power of 420 W for 1.5 hours. After the extraction was completed, the clarified filtrate and filter residue were obtained by suction filtration under reduced pressure. The filter residue was collected, and then 480 g of 60% ethanol aqueous solution was added, and ultrasonic extraction was performed at 50°C with a power of 420W for 1.5 hours. Sucti...

Abstract

The invention discloses a preparation method of a camellia flower/leaf extract. The preparation method comprises the following steps: taking fresh camellia flowers and/or camellia leaves as raw materials, carrying out cleaning, crushing, ultrasonic-assisted extraction, concentrating, refining and the like to obtain the extract. Compared with the conventional extraction method, the preparation method disclosed by the invention is simple, convenient and rapid, controllable in cost and easy for realizing batch production, the yield of flavone and polyphenol in the obtained extract is obviously improved, and the oxidation resistance is enhanced.

Description

technical field [0001] The invention belongs to the technical field of natural product extraction, and in particular relates to a preparation method of camellia flower / leaf extract. Background technique [0002] Camellia is a plant of the genus Camellia in the family Theaceae, an evergreen broad-leaved forest woody plant, also known as camellia, camellia, and winter resistance, and is one of the top ten famous flowers in China; camellia is widely distributed and is mainly produced in Zhejiang, Yunnan, Jiangxi, and Sichuan in my country and so on. Camellia seed is a pure natural high-grade oil plant unique to my country. At present, the research and utilization of camellia are mainly concentrated on camellia seed, camellia seed meal, and camellia seed shell, while the research and utilization of camellia flower and leaves are relatively few. Camellia, as the reproductive organ of the camellia tree, concentrates the nutrients in the camellia, rich in protein, amino acid, reduc...
