Embodiment 1

[0039] A method for preparing high-purity naringin by using Huajuhong:

[0040] A. The preparation of Huajuhong: pick the immature fresh Zhengmao Huazhou Juhong young fruit in June, wash, dry, and dry at 65°C for 50 hours on low heat, and dry the water.

[0041] B. Extraction of naringin: steam for 10 minutes to soften, slice into 5 mm, and extract naringin by ethanol reflux. The extraction conditions are as follows: ultrasonic power 80W, extraction time 120 minutes, ethanol volume fraction 60%, extraction temperature 60°C, solid-liquid ratio 1g:180ml.

[0042] C. Preparation of high-purity naringin: spin-steam and concentrate the ethanol extract to prepare the extract, recycle ethanol, dry the extract, add 6 times the quality of distilled water, let it stand until the yellow precipitate precipitates, filter, and dry. The obtained yellow powder was characterized by infrared, electron microscope and liquid phase. The purity of naringin was measured by liquid phase to be over 9...

Embodiment 2

[0044] A method for preparing high-purity naringin by using Huajuhong:

[0045] A. Preparation of Huajuhong: Pick the whole immature fresh Zhengmao Huazhou Juhong young fruit in May, wash, dry in the air, and dry at 75°C for 40 hours on low heat, and dry the water.

[0046] B. Extraction of naringin: steam for 8 minutes to soften, slice into 3 mm, and extract naringin by ethanol reflux. The extraction conditions are as follows: ultrasonic power 80W, extraction time 30 minutes, ethanol volume fraction 30%, extraction temperature 30°C, solid-liquid ratio 1g:60ml.

[0047] C. Preparation of high-purity naringin: spin-steam and concentrate the ethanol extract to prepare the extract, recycle ethanol, dry the extract, add 4 times the quality of distilled water, let it stand until the yellow precipitate precipitates, filter, and dry. The obtained yellow powder was characterized by infrared, electron microscopy and liquid mass, and the purity of naringin was measured by liquid phase ...

Embodiment 3

[0049] A method for preparing high-purity naringin by using Huajuhong:

[0050] A. Preparation of Huajuhong: Pick the whole fruit of Zhengmao Huazhou Juhong young fruit produced in the local orchard of Huazhou, a prefecture-level city in Maoming City, at the end of May and early June, and dry at 70°C for 45 hours to dry out the water.

[0051] B. Extraction of naringin: steamed for 9 minutes to soften, sliced ​​into 4 mm, then crushed to 50 mesh, and refluxed with ethanol to extract flavonoids. The extraction conditions are as follows: ultrasonic power 80W, extraction time 80 minutes, ethanol volume fraction 45%, extraction temperature 45°C, solid-liquid ratio 1g:120ml.

[0052] C. Preparation of high-purity naringin: Rotary steaming and concentrating the ethanol extract of Huajuhong to prepare the extract, reclaiming ethanol, and drying the extract (every 500g of Huajuhong obtains about 195-205g of extract), add 5 times the quality of Distilled water, adjust the density of t...

Abstract

The invention provides a method for preparing naringin by using exocarpium, and belongs to the technical field of preparation of natural products. The method comprises the following steps: (1) puttingthe exocarpium into ethanol water with the volume fraction of 30-60%, and extracting at 30-60 DEG C, so as to obtain an exocarpium ethanol extract; (2) evaporating in a rotary way and concentrating the exocarpium ethanol extract to obtain an extractum; (3) mixing the extractum with water, wherein the mass ratio of the extractum to the water is 1 to 4-6; standing for 5-8 hours at 5-15 DEG C, precipitating a yellow precipitate, carrying out solid-liquid separation, so as to obtain the naringin. The naringin prepared according the method provided by the invention is simple in process, the purityof a naringin product is more than 95%, and the yield is higher than 9.0%.

Description

technical field [0001] The invention belongs to the technical field of natural product preparation, and in particular relates to a method for preparing naringin by using tangerine. Background technique [0002] Huajuhong belongs to the Rutaceae citrus genus pomelo variety Huazhou pomelo. The medicinal ingredient is immature or nearly mature dry outer epidermis. It is clinically used to treat wind-cold cough, phlegm and qi reversal, food accumulation and heat, and nausea. It is a famous and precious specialty medicinal material in Guangdong. Naringin is one of the main active ingredients of Tangerine. In addition to its biological activities such as decomposing sugar in the liver, lowering lipids, anti-oxidation, anti-virus, anti-bacterial, and treating pneumonia, it also has biological activities such as treating HIV, sun protection, and treating osteoporosis. , treating intervertebral disc degeneration and treating ovarian cancer, etc., and can also synthesize a new type o...
