Problems solved by technology

[0005] Based on the increasing consumption of orange juice in the domestic and foreign markets, there is nowhere to place discarded orange peels. Although there are reports on the extraction and component identification of essential oils and hesperidin in orange peels, there are few reports on how to fully use them in the industry. Using this resource, what recycling method can be used to maximize economic benefits

Embodiment 1

[0041] Such as Figure 7 Shown, the continuous extraction method of volatile oil and flavonoid glycosides composition in a kind of navel orange peel, comprises the following steps:

[0042] Extraction of volatile oil from navel orange peel: take 400g of washed fresh navel orange peel (remove the inner orange network of the peel), make several streaks on the cortex with a blade, and then cut into small pieces (about 0.5cm 2 ), put it into a 5000mL round-bottom flask, add 1000mL of distilled water according to the ratio of solid to liquid of 1:2.5, and extract the volatile oil components according to the Chinese Pharmacopoeia Appendix XD A method, and the heating temperature should not be too high to ensure sufficient condensation effect. Extract for 5 hours until the amount of volatile oil no longer increases, then stop heating, and after standing for 30 minutes, open the valve, slowly release the water layer, then add 2 mL of ether to the volatile oil extractor, shake well, re...

Embodiment 2

[0091] A continuous extraction method of volatile oil and flavonoid glycosides in navel orange peel, comprising the following steps:

[0092] Extraction of volatile oil from navel orange peel: take 400g of washed fresh navel orange peel (remove the inner orange network of the peel), make several streaks on the cortex with a blade, and then cut into small pieces (about 0.5cm 2 ), put it into a 5000mL round-bottom flask, add 1000mL of distilled water according to the ratio of solid to liquid of 1:2.5, and extract the volatile oil components according to the Chinese Pharmacopoeia Appendix XD A method, and the heating temperature should not be too high to ensure sufficient condensation effect. Extract for 5 hours until the amount of volatile oil no longer increases, then stop heating, and after standing for 30 minutes, open the valve, slowly release the water layer, then add 2 mL of ether to the volatile oil extractor, shake well, release the oil layer, evaporate the ether, and obt...

Embodiment 3

[0095] A method for continuous extraction of volatile oil and flavonoid glycosides in navel orange peel, comprising the following steps: extraction of navel orange peel volatile oil: get 400g of washed fresh navel orange peel (remove the inner orange network of the peel), and use a blade to make several streaks in the cortex Then cut into small pieces (about 0.4cm 2 ), put it into a 5000mL round bottom flask, add 400mL of distilled water according to the ratio of solid to liquid of 1:1, and extract the volatile oil components according to the Chinese Pharmacopoeia Appendix XD A method. The heating temperature should not be too high to ensure sufficient condensation effect. Extract for 4 hours until the amount of volatile oil no longer increases, then stop heating, after standing for 40 minutes, open the valve, slowly release the water layer, then add 4mL ethyl acetate to the volatile oil extractor, shake well, release the oil layer, evaporate the ethyl acetate, Crude volatile ...

Abstract

The invention discloses an extraction and detection method for benzene and flavonoid glycoside ingredients in navel orange peel. The method comprises the following steps that: firstly, extracting thebenzene in the navel orange peel by a water vapor distillation method, and then, continuously extracting the flavonoid glycoside ingredients in residues by 60% ethyl alcohol. By use of the detection method, essential oil extraction and flavonoid glycoside extraction are artfully combined, the technology is simple, and industrial production requirements are met; in addition, in virtue of GC-MS (GasChromatography-Mass Spectrometer) and UPLC (Ultra Performance Liquid Chromatography)-Q / TOF (Quadrupole Time of Flight) technologies, ingredients prepared by separation are independently subjected toqualitative analysis, the most important ingredient, i.e., hesperidin, is subjected to HPLC-DAD (Diode Array Detector) content measurement, main ingredients and contents in the navel orange peel can be made clear, and a research direction and a technological base are provided for the development of the navel orange peel.

Description

technical field [0001] The invention relates to a method for continuous extraction, detection and analysis of volatile oil and flavonoid glycosides in navel orange peel, and belongs to the technical field of extraction and analysis of natural product effective components. Background technique [0002] Navel orange, formerly known as: sweet orange. Alias: orange, orange, sweet orange. Belonging to the citrus plant of Rutaceae, the ripe fruit of sweet orange (Citrussinensis (L.) Osbeck). Orange is mild in nature and sweet in taste. It is mainly used to treat loss of appetite, abdominal distension, loose stool or diarrhea. China's navel orange industry is mainly based on the sale of fresh navel oranges and making orange juice. Because navel orange has a strong fragrance and attractive color, and because it contains rich nutrients, such as flavonoids, vitamin C, carotenoids, etc., orange juice has become one of the most popular fruit juices in the domestic and foreign markets...
