What is Lychee Polyphenols?

Litchi is the fruit of Sapindaceae plant Litchi, which originates in southern my country and is most cultivated in Guangdong, Guangxi, Fujian, Sichuan, Taiwan, Yunnan and other places. Litchi has high nutritional value and is rich in sugar and VC. The medicinal value of lychee is also high. It is a statutory dual-purpose plant for medicine and food announced by the Ministry of Health. It is warm in nature, sweet and sour. , Nourish the liver, regulate qi, and benefit blood; while lychee core has the effect of warming the middle, regulating qi and relieving pain.

Litchi contains a large amount of Lychee Polyphenols, mainly polyphenols. Polyphenols refer to a group of chemical elements in plants, named after having multiple phenolic groups. Polyphenols have a strong antioxidant effect. Oriental tea and western red wine contain polyphenols. Polyphenols can prevent the aging of the human body and brain, and have anti-cancer activity, which has high economic value.

Lychee Polyphenols are typically used in anti-aging solutions as they aid reduce the aging process as well as offer the skin with a lot of dampness while recovering its flexibility as well as natural luster. It likewise has anti-acne residential or commercial properties such as anti-inflammatory, antioxidant, as well as anti-bacterial, which efficiently combat acne-causing microorganisms, therefore minimizing swelling and also acne scarring.

Preparation of Lychee Polyphenols

Extraction process: Transfer all the crushed lychees to a beaker, add 1:8g/ml distilled water to fully immerse the lychee skin under the liquid surface; boil and keep soaking at 100°C for 0.5h, then lower the temperature to After soaking at 70°C for 4 hours, filter and collect the filtrate; wash the filter residue with warm water, repeat 3 times, and collect the filtrate obtained each time; Soak for 8 hours at ℃, filter again and collect the filtrate, finally combine all the filtrates and dry to obtain the crude extract of Lychee Polyphenols;

Purification process: after dissolving the crude extract of Lychee Polyphenols with a 20% ethanol solution with a material-to-liquid ratio of 1:10g/ml, add ethyl acetate equal to the ethanol solution and let it stand for about 10 minutes, place it at room temperature, and separate the liquids. After separation with a separatory funnel, an ethyl acetate layer and an ethanol layer were obtained respectively; the ethanol layer was extracted with 10 ml of ethyl acetate, and after separation, the ethanol layer was evaporated to dryness to obtain a dry purified intermediate product.

According to the ratio of purified intermediate product: resin wet weight about 1:4, add the purified intermediate product into the beaker with the treated resin ADS-7, shake it every 5min for 10s for 2h; then let it stand for 24h to make it When saturated adsorption is reached, the eluent is poured out, and then the macroporous resin is eluted with 20% ethanol and distilled water for about 3-4 times respectively, and the water extract of Lychee Polyphenols is obtained by filtration and dried. Experimental results: The crude polyphenol contents are: litchi skin 213.96ug/g, litchi core 209.33ug/g.

 

Detection Method of Lychee Polyphenols

Litchi polyphenol sample preparation: Weigh 10g of litchi skin and litchi core for crushing, add distilled water to the crushed material according to the material-liquid ratio of 1:8g/ml, boil for 0.5h, soak in 70°C water for 4h, filter and separate to obtain The first filtrate and the first residue, and finally dry the residue, add 50% acetone to the residue according to the solid-liquid ratio of 1:6g/ml, soak at 60°C for 8h, and then filter and separate to obtain the second filtrate and the second Residue, soak the secondary residue in hot water, filter and collect the third filtrate, combine the primary filtrate, the second filtrate and the third filtrate and dry it to obtain the crude extract, transfer the crude extract to a 25ml volumetric flask, add distilled water Dilute to the mark to prepare litchi polyphenol samples.

Detection of polyphenols in lychee:

Accurately measure 2.0, 4.0, 6.0, 8.0, 1.0, 1.2, 1.4 ml of gallic acid reference solution with a concentration of 0.004 mg/ml, put them in 10 ml brown measuring bottles, and then add 0.5 ml of 0.1 mol/L FeCl3 solution, 0.5ml of K3Fe(CN)6 solution with a concentration of 0.0008 mol/L, and 0.5ml of HCl solution with a concentration of 0.1000 mol/L were all dilute to 10 mL and shaken well, and left for more than 10 minutes. Blank, measure the absorbance value at a wavelength of 670nm, draw the standard curve with the concentration of gallic acid reference substance solution as the abscissa, and the absorbance value as the ordinate, and the regression equation is y=0.009x+0.1563, r=0.9923.

Sample detection: Take 3ml of lychee polyphenol sample and add it to a 10ml volumetric flask, then add 0.5ml FeCl3 solution with a concentration of 0.1 mol/L, 0.5ml K3Fe(CN)6 solution with a concentration of 0.0008 mol/L, and 0.5ml concentration Make a 0.1000 mol/L HCl solution and set the volume to 10 ml, place it for more than 10 min to measure the absorbance value at a wavelength of 670nm, and calculate the content based on the standard curve.

In a preferred embodiment, before measuring the absorbance value, the gallic acid reference substance solution needs to be placed for 15min after adding FeCl3, K3Fe(CN)6 and HCl solution to constant volume, and then measure the absorbance value; the litchi polyphenol sample is After adding FeCl3, K3Fe(CN)6 and HCl solution to constant volume, it needs to stand for 15min, and then measure the absorbance value.

The utilization of polyphenols in litchi, the development of a new plant polyphenol resource, and the application research in the fields of cosmetics, food, medicine, etc., will have a positive effect on the comprehensive utilization of litchi resources in my country and the development of post-harvest deep processing technology of litchi. significance. Usually people will throw away the shell and core after eating litchi. This paper uses litchi waste (shell and core) as raw material to extract the polyphenols, and then determine the content of litchi polyphenols by targeted detection methods. The components in litchi were quantitatively analyzed, and the data of polyphenols in litchi were collected, which is beneficial to the subsequent comprehensive development of litchi.
