Embodiment Construction

[0019] Such as figure 1 Shown, a kind of method extracting hesperidin from Fructus Fructus Aurantii, comprises the steps:

[0020] 1) Obtain the raw materials, among which, ultrasonic methanol extraction is used for 1 hour of raw material content detection, and the extract is directly detected. The raw material content requires hesperidin ≥ 25% and synephrine ≥ 0.9%;

[0021] 2) After soaking the raw materials, crush them until they can pass through a 20-mesh sieve;

[0022] 3) The raw materials are boiled to remove impurities for 1 hour, and the boiled liquid is drained;

[0023] 4) Use 0.8% and 0.5% sodium carbonate solution to remove impurities, discard the removal solution, and wash with water until neutral;

[0024] 5) Extract twice with sodium hydroxide and calcium hydroxide aqueous solution. During the extraction process, sodium hydroxide or calcium hydroxide can be supplemented appropriately to ensure that the pH of the extract is 13-14, and the extracts are combined...

Abstract

The invention belongs to the technical field of natural medicine extraction and particularly relates to a method for obtaining hesperidin. According to the method, the rutaceous plant fructus aurantii immaturus serves as the raw material, impurities are removed with a cold-maceration method, coarse crystals are separated out with an alkali dissolution and acid deposition method, secondary crystallization is carried out with alkali sodium alkoxide, and hesperidin is obtained. By means of the method, waste of the raw material can be fully reduced, environment pollution is reduced, hesperidin in fructus aurantii immaturus can be efficiently extracted and separated, and a very good technical effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of natural medicine extraction, and specifically relates to a method for obtaining hesperidin by using citrus citrus fruit as a raw material, removing impurities by cold soaking, and separating coarse crystals by alkali extraction and acid precipitation, and secondary crystallization by sodium alkali alcohol. Background technique [0002] Hesperidin is a class of flavonoids present in citrus plants of Rutaceae (Rutaceae), which has a flavone oxyglycoside structure and is weakly acidic. The pure product is white needle-like crystal, which is the main component of vitamin P. Studies in recent years have shown that hesperidin has the functions of maintaining osmotic pressure, enhancing capillary toughness, shortening bleeding time, and lowering cholesterol. Drugs are one of the main raw materials of the patent medicine "Main Tong". It can be used as a natural antioxidant in the food industry and also in the c...
