Abstract

The invention provides a novel process method for extracting hesperidin. The novel process method comprises the following steps: crushing dried immature bitter oranges, carrying out pretreating with asodium citrate solution, carrying out extracting with an alkali liquor, adding acid for crystallization, and carrying out filtering and drying. The core of the application is the pretreatment processwith the sodium citrate solution; in the pretreatment process, a raw material can be washed; meanwhile, isomers of the hesperidin in part of raw material components can be removed. The concentrationof the sodium citrate solution is strictly controlled, so impurities in a hesperidin product can be effectively reduced, and the content of the hesperidin is increased. During crystallization, the pHvalue of an extracting solution is adjusted to be 4.5-6.5 by using the acid.

Description

technical field

[0001] The invention relates to the technical field of plant extraction, in particular to a new process for extracting hesperidin. Background technique

[0002] Chinese aliases of hesperidin: hesperidin, nobiletin, nobiletin, dihydroflavone glycoside. Hesperidin is the main active ingredient of tangerine peel, molecular formula C28H34O15. Studies have shown that hesperidin has physiological functions such as anti-oxidation, anti-allergy, antibacterial and anti-inflammatory, anti-virus and anti-cancer, prevention of cardiovascular diseases, lowering blood pressure, lowering low-density cholesterol, etc., and has high medicinal value. In addition, it is used as a natural oxidizing agent in the food and cosmetic industries.

[0003] At present, the sources of extracting hesperidin mainly include young orange fruits and young orange fruits. The extraction techniques mainly include Soxhlet extraction, alkali extraction and acid precipitation, microwave extracti...
