Embodiment 1

[0054] Remove the skin of the young fruit of Shatian pomelo, dry the skin at 60°C, pulverize with a pulverizer, and pass through a 40-mesh sieve to obtain a crude pomelo peel powder with a size below 40 mesh. Weigh 100.3g of crude pomelo peel powder, add 601mL of petroleum ether, stir evenly, let it stand for 24 hours, filter to remove petroleum ether, and evaporate the powder to dry petroleum ether for later use.

[0055] The aqueous solution of sodium lauryl sulfate is added in the flask that pomelo peel powder is housed, wherein, the massfraction of sodium lauryl sulfate in the aqueous solution of sodium lauryl sulfate is 0.2%, sodium lauryl sulfate The mass ratio of aqueous solution and pomelo peel powder is 2:1, forms solid-liquid mixture, soaks 2h, adds water to mix afterwards and transfers the flask that this solid-liquid mixture is housed in the ultrasonic cleaning machine, and connects distillation unit, ultrasonic cleaning machine The ultrasonic power is 400W, and th...

Abstract

The invention relates to an extraction technology of naringin. The extraction technology comprises the following steps: drying, crushing and sieving shaddock peels, so as to obtain a crude product, putting the crude product into a solvent to soak the crude product, and preserving solid after solid-liquid separation is performed, so as to obtain shaddock peel powder; feeding the shaddock peel powder into a water solution containing a surfactant, performing distillation extraction after the shaddock peel powder is sufficiently soaked, meanwhile performing ultrasonic treatment through ultrasonicwave, and then performing solid-liquid separation and preserving filtrate; evaporating and concentrating the filtrate, so as to obtain a naringin concentrated solution; performing sample loading and elution on the naringin concentrated solution, and preserving target effluent; and performing evaporating and concentrating, cooling crystallization and separation on the target effluent, so as to obtain crystalline solid naringin. The technology adopts an extraction method of the combination of the ultrasonic wave and the surfactant, effectively improves the extraction rate and purity of naringin,and is simple in processes, and environmentally-friendly and pollution-free.

Description

technical field [0001] The invention relates to a method for purifying natural products, in particular to a process for extracting naringin. Background technique [0002] Naringin is a natural pigment extracted by modern biotechnology from the peels and fruits of pomelo, grapefruit, lime and its varieties. In addition, it is also the main active ingredient of Chinese herbal medicine Rhizoma Drynariae, Fructus Aurantium, Fructus Aurantium, and Tangerine. As a dihydroflavonoid compound, since there is no conjugation between the A ring and the B ring, naringin has a strong ultraviolet absorption peak at 282nm, which makes naringin display various biological activities and pharmacological effects, such as Including anti-inflammation, reducing the formation of thrombus, improving local microcirculation and nutrient supply, etc. [0003] The method of extracting naringin in the traditional technology is mostly organic solvent extraction method, promptly extracts naringin with et...
