Abstract

The invention discloses a preparation method for extracting hesperidin from citrus aurantium, comprising the following steps: (1) preparing the raw material, i.e. citrus citrus fine powder, and pouring it into an extraction tank; (2) preparing an alkali solution to soak the material in the tank After the treatment, empty the liquid and turn over the material; (3) configure the alkali solution to heat the tank material; (4) configure the alkali solution to perform the first percolation treatment on the tank material, then drain the liquid and turn over the material; (5) Alkali solution is prepared to carry out the second diafiltration treatment on the material in the tank, and then the liquid is emptied and then turned over; (6) pumping in the extract to extract hesperidin; (7) isolating hesperidin crystallization; (8) treating hesperidin Glycoside crystals were filtered and dried. The invention has the beneficial effects of simple process, low cost and high purity of the extracted hesperidin.

Description

technical field [0001] The invention relates to a preparation method for extracting hesperidin from Citrus aurantium. Background technique [0002] Citrus aurantium, recorded in the 2005 edition of the Chinese Pharmacopoeia, page 172, is the dried young fruit of the Rutaceae plant sour orange and its cultivars or sweet orange. It is a commonly used folk Chinese herbal medicine. and other effects. [0003] Citrus aurantium is one of the raw materials for extracting hesperidin. Hesperidin is a yellow-brown fine powder. It is too complicated and expensive, and the purity is not too high. Contents of the invention [0004] In order to overcome the deficiencies of the prior art, a preparation method for extracting hesperidin from Fructus Citrifolia is provided, the preparation method has simple process, low cost, and the extracted hesperidin has high purity. [0005] The present invention is achieved through the following technical solutions: a preparation method for extract...
