Embodiment 1

[0030] A method for extracting hesperidin from navel orange fallen fruit and navel orange peel, such as Figure 1-Figure 3 as shown,

[0031] The steps are as follows:

[0032] (1) Drying and powdering: Put the fallen navel orange fruit and peel in a dryer to dry, and then crush them into powder with a pulverizer to prepare navel orange fallen fruit and navel orange peel powder. The navel orange fallen fruit and navel orange peel are air-dried at 80°C way to dry.

[0033] (2) Soxhlet extraction: Add 250mL petroleum ether in a 500mL round bottom flask, install a Soxhlet extractor, weigh 10 grams of step (1) sample (the content of hesperidin in the sample is 2.8%) powder and put it into the filter paper tube , put the filter paper tube into the Soxhlet extractor, and finally install the condenser tube, pass water and heat; during the process, it can be observed that the petroleum ether is volatilized by heating until the condenser tube is cooled and dripped into the Soxhlet ex...

Abstract

The invention belongs to the field of chemical and pharmaceutical engineering, and relates to a method for extracting hesperidin from navel orange fruits and navel orange peels. A lot of navel orange fruits and navel orange peels are abandoned, so that resource is waste. The method is used for extracting hesperidin from navel orange fruits and navel orange peels, which comprises the following steps: The method comprises the following steps: 1) drying and grinding; 2) Soxhlet extraction; 3) rotary evaporation; 4) suction filtration and extraction of crude hesperidin; 5) column chromatography isolation; and 6) extraction of fine hesperidin. The method has the advantages that 1) navel orange fruits and navel orange peels are comprehensively used and the valuable components are recovered, resource waste is reduced, resource utilization rate is increased; 2) the hesperidin recovery rate is high, crude hesperidin recovery rate is 89.3%, and the fine hesperidin recovery rate is 93.6%; and 3) by recovering the hesperidin in the navel orange fruits and navel orange peels, economic benefit of the navel orange industry is increased.

Description

technical field [0001] The invention belongs to the field of chemical industry and pharmacy, and in particular relates to a method for extracting hesperidin from navel orange fruit drop and navel orange peel. Background technique [0002] The structural formula of hesperidin: [0003] [0004] Hesperidin (Hesperidin), molecular formula C 28 h 34 o 15 , a dihydroflavonoid compound, mainly exists in the peel of citrus, sweet orange and lemon, accounting for about 3% of the weight of the peel. The pure product is light yellow crystalline powder. Hesperidin has pharmacological activities such as anti-inflammation, anti-oxidation, and anti-cancer. It is widely used in chemical, pharmaceutical, food and other fields, and has extremely wide development and application value. [0005] Navel oranges are easy to form flowers, but the fruit setting rate of fruit trees is low, generally about 5%, and the young navel oranges fall due to physiological reasons. There are two obviou...
