Problems solved by technology

However, the active ingredients in tangerine peel are almost surrounded by plant cell walls, and the traditional extraction methods cannot break the cell walls surrounding hesperidin, and there is a huge mass transfer resistance, so that the extraction effect is greatly limited, and the extraction rate is low. The effect is not ideal, resulting in a serious waste of resources

Embodiment 1

[0038] The present invention provides a specific embodiment for preparing dried tangerine peel extract, the steps are as follows:

[0039] Crush the tangerine peel, accurately weigh a certain amount of tangerine peel powder and pour it into the extraction container, add water according to the ratio of solid to liquid 1:10; put steam into the jacket of the extraction container to maintain the temperature of the extraction liquid at 50-60 °C; add prepared hydrochloric acid or sodium hydroxide to the extraction container to adjust the pH of the extract to 3.0-3.5; add 0.5% cellulase and 2.0% pectinase to the extract respectively, and stir for extraction for 3 hours.

[0040] Add the measured ethanol solution after the enzymolysis reaction, so that the extraction conditions at this time are solid-to-liquid ratio 1:30, ethanol concentration 65%, the extraction container is heated up until the temperature of the extract reaches 80°C, and the extraction is continued for 3 hours with s...

Embodiment 2

[0043] Crush the tangerine peel, accurately weigh a certain amount of tangerine peel powder and pour it into the extraction container, add water according to the ratio of solid to liquid 1:9; put steam into the jacket of the extraction container to maintain the temperature of the extraction liquid at 50-60 °C; add prepared hydrochloric acid or sodium hydroxide to the extraction container to adjust the pH of the extract to 3.0-3.5; add 1% cellulase and 3% pectinase to the extract, and stir for 2 hours.

[0044] Add the measured ethanol solution after the enzymolysis reaction, so that the extraction conditions at this time are solid-to-liquid ratio 1:35, ethanol concentration 70%, the extraction container is heated up to the temperature of the extraction solution reaches 85 ° C, and the extraction is continued for 2 hours with stirring; after the extraction is completed The extract is filtered through a duplex filter; the filtered extract is concentrated under reduced pressure in...

Embodiment 3

[0047] Crush the tangerine peel, accurately weigh a certain amount of tangerine peel powder and pour it into the extraction container, add water according to the ratio of solid to liquid 1:8; put steam into the jacket of the extraction container to maintain the temperature of the extraction liquid at 50-60 °C; add prepared hydrochloric acid or sodium hydroxide to the extraction container to adjust the pH of the extract to 3.0-3.5; add 1% cellulase and 2% pectinase to the extract, and stir for 3 hours.

[0048] Add the measured ethanol solution after the enzymolysis reaction, so that the extraction conditions at this time are solid-to-liquid ratio 1:40, ethanol concentration 70%, the temperature of the extraction container is raised to 90°C, and the extraction is continued for 3 hours with stirring; The extract is filtered through a duplex filter; the filtered extract is concentrated under reduced pressure in a concentration system until it has no alcohol smell; the concentrate ...

Abstract

The invention discloses a dried tangerine peel extract preparation method, wherein the dried tangerine peel extract is prepared by using dried tangerine peel as a raw material through cellulase and pectinase combined enzymolysis. The invention further discloses the dried tangerine peel extract prepared by using the method and applications of the dried tangerine peel extract. According to the present invention, by using the cellulase and pectinase combined enzymolysis method, the characteristics of high efficiency, simple and convenient operation, mild reaction condition and the like can be provided; after the enzymolysis reaction, ethanol is used as a solvent to extract; and the method has advantages of high yield, safety, effectiveness and solvent recovery, and is suitable for industrial production.

Description

technical field [0001] The invention belongs to the technical field of natural product separation, and relates to a method for preparing tangerine peel extract, tangerine peel extract and application thereof. Background technique [0002] Dried orange peel is the dried and mature pericarp of Rutaceae plant tangerine and its cultivars. "Guang Chen Pi" is the dried and mature peel of Chazhi Tangerine, which is mainly produced in Xinhui, Guangdong, and is one of the top ten authentic medicinal materials in Guangdong. The active ingredients of dried tangerine peel include volatile oil and flavonoids (hesperidin is the main one), and the content of hesperidin is generally used as a quality index for evaluating tangerine peel. Hesperidin belongs to dihydroflavone glycosides and is one of the main components of tangerine peel. Studies have found that hesperidin has various pharmacological activities such as anti-inflammation, anti-oxidation, anti-bacterial, anti-cancer, immune re...
