Problems solved by technology

Due to the relatively concentrated listing, backward storage and transportation conditions and insufficient storage and preservation technology, only some longans are directly consumed as fruits, and a large amount of longan is used for processing longan meat, canned longan syrup and longan paste, etc., while the remaining fruit cores are directly used as waste. throw away

Embodiment 1

[0024] (1), extraction: collect the discarded fruit stones of longan processing in the longan fruit field, dry naturally, and pulverize through a 20-mesh sieve to obtain longan fruit stone powder. Take 100g of longan fruit core powder in a 2000mL three-neck flask, add 1500mL of anhydrous acetone, install a stirring device with a seal, plug the other two ports tightly, stir at room temperature for 1 hour, let stand for 1 hour, and pour out the upper layer as much as possible (basically clear, another For treatment), discard the upper layer; add 1500mL 60% acetone for the second time, stir at room temperature for 6h, then stand still for 1h, pour out the upper layer as much as possible and filter; add 1500mL 60% acetone for the third time, stir at room temperature for 4h, stand still 1h, filter; combine the second and third filtrates, recover acetone by atmospheric pressure rotary evaporation to obtain polyphenols, and dilute the obtained polyphenols with water until the concentr...

Embodiment 2

[0031] (1), extraction: collect the discarded fruit stones of longan processing in the longan fruit field, dry naturally, and pulverize through a 20-mesh sieve to obtain longan fruit stone powder. Take 100g of longan fruit core powder in a 2000mL three-necked flask, add 1200mL of anhydrous acetone, install a stirring device with a seal, plug the other two ports tightly, stir at room temperature for 2 hours, let stand for 1 hour, pour out the upper layer as much as possible (basically clear, another For treatment), discard the upper layer; add 1500mL 55% acetone for the second time, stir at room temperature for 5h, then stand still for 1h, pour out the upper layer as much as possible and filter; add 1000mL 55% acetone for the third time, stir at room temperature for 4h, stand still 1h, filter; combine the second and third filtrates, recover acetone by atmospheric pressure rotary evaporation to obtain polyphenols, and dilute the obtained polyphenols with water to a polyphenol con...

Embodiment 3

[0036] (1), extraction: collect the discarded fruit stones of longan processing in the longan fruit field, dry naturally, and pulverize through a 20-mesh sieve to obtain longan fruit stone powder. Take 100g of longan fruit core powder in a 2000mL three-neck flask, add 1000mL of anhydrous acetone, install a stirring device with a seal, plug the other two ports tightly, stir at room temperature for 1h, let stand for 1h, pour out the upper layer as much as possible (basically clear, another For treatment), discard the upper layer; add 1000mL 50% acetone for the second time, stir at room temperature for 4h, then stand still for 1h, pour out the upper layer as much as possible and filter; add 1000mL 50% acetone for the third time, stir at room temperature for 6h, stand still 1h, filter; combine the second and third filtrates, recover acetone by rotary evaporation under normal pressure to obtain polyphenols, dilute the obtained polyphenols with water to a polyphenol concentration of ...

Abstract

The invention discloses a longan fruit stone polyphenol extraction and purification method and its application in preparing polyphenol whitening cosmetics. The longan fruit stone powder is treated three times with anhydrous acetone and 50-70% acetone aqueous solution respectively, the filtrates of the second and third times are combined, and the acetone is recovered to obtain polyphenols; the extracted polyphenols are purified by macroporous adsorption resin, Concentration to dryness in vacuo yielded purified polyphenol. The method of the present invention has a high extraction rate, the organic solvent used is easy to recycle, the water in the extraction liquid does not need to be heated and evaporated, the room temperature or low temperature treatment is beneficial to protect the product and save energy, and the product solubility becomes better after purification, which is convenient for compounding products. Moreover, it provides a brand-new use for longan fruit stones, and develops four kinds of cosmetics with great market prospects: polyphenol whitening nutrition facial cleanser, polyphenol whitening nutrition water, polyphenol whitening nutrition milk, polyphenol whitening nutrition cream, also for The comprehensive application development of longan fruit stone provides a way with broad prospects.

Description

Technical field: [0001] The invention belongs to the field of biomedicine, and in particular relates to a method for extracting and purifying longan fruit stone polyphenols and its application in preparing polyphenol whitening cosmetics. Background technique: [0002] Longan (Dimocarpus longan Lour.) is an evergreen fruit tree of the genus Dimocarpus Lour. in the family Sapindaceae. It is grown as a cash crop in many countries such as China, Thailand, India and Vietnam. my country is distributed in Fujian, Taiwan, Guangxi, Guangdong, Hainan, Sichuan, Guizhou, Yunnan and other provinces and regions, and there are large-scale plantings in Fujian, Guangdong, and Guangxi. The common name of longan is longan, also known as longan, bimu, lychee slave, puzzle, sub-lychee, round eye, Sichuan marble, Lizhu, swallow egg, honey spleen, shark tear, wood bomb, embroidered wood group, etc. Famous fruit, its pulp is milky white or pale white, with crispy and sweet flesh. As a nourishing...
