specific Embodiment approach 1
[0014] Wash, peel and slice the fresh platycodon root, dry it to constant weight at 60°C, crush it through a 100-mesh sieve, and carry out microwave-assisted treatment with a solid-liquid ratio of 1:30, an ethanol concentration of 50%, and a microwave power of 210w. Microwave for 60s, filter the extract, extract the filter residue once more under this condition, combine the two filtrates, and complete the entire extraction process of bellflower polyphenols, and the filtrate is rotary evaporated and vacuum freeze-dried to obtain bellflower polyphenols.
specific Embodiment approach 2
[0015] Wash, peel and slice the fresh platycodon root, dry at 60°C to constant weight, crush through a 100-mesh sieve, and carry out microwave-assisted treatment with a solid-liquid ratio of 1:25, an ethanol concentration of 50%, and a microwave power of 210w. Microwave for 60s, filter the extract, extract the filter residue once more under this condition, combine the two filtrates, and complete the entire extraction process of bellflower polyphenols, and the filtrate is rotary evaporated and vacuum freeze-dried to obtain bellflower polyphenols.
specific Embodiment approach 3
[0016] Wash, peel and slice the fresh platycodon root, dry it to constant weight at 60°C, crush it through a 100-mesh sieve, and carry out microwave-assisted treatment. The ratio of solid to liquid is 1:30, the concentration of ethanol is 60%, and the wave power is 210w. Microwave for 60s, filter the extract, extract the filter residue once more under this condition, combine the two filtrates, and complete the entire extraction process of bellflower polyphenols, and the filtrate is rotary evaporated and vacuum freeze-dried to obtain bellflower polyphenols.

Abstract
The invention discloses a microwave-assisted method for extracting polyphenol from platycodon grandiflorum roots and belongs to the technical field of extraction of effective products in agriculturalproducts. The microwave-assisted method comprises the following specific steps: after washing, peeling and slicing fresh platycodon grandiflorum roots, drying at 60 DEG C until the weight is constant;crushing and sieving by a sieve with the size of 100 meshes; carrying out microwave-assisted treatment, wherein the material / liquid ratio is 1 to 30, the ethanol concentration is 50 percent, the microwave powder is 210w and the microwave time is 60s; filtering an extracting solution and extracting filter dreg at the same condition for 1 time; combining filtrate of two times to finish a whole extraction process of platycodon grandiflorum polyphenol; and carrying out rotary evaporation and vacuum freezing and drying on filtrate to obtain the platycodon grandiflorum polyphenol with the concenteation of 6.49mg / g. The platycodon grandiflorum polyphenol is prepared by adopting the method, and the method has the advantages of simple technological operation, low production cost, time saving and labor saving, high extraction rate and good quality.
Description
technical field [0001] A method for microwave-assisted extraction of polyphenols in platycodon root, belonging to the technical field of extraction of active ingredients of agricultural products, specifically relates to a microwave extraction of polyphenols processing technology, the final extraction rate of polyphenols is 6.49mg / g, which is polyphenols The extraction method of the compound provides the basis. Background technique [0002] Platycodon grandiflora is a herbaceous plant of Campanulaceae family Campanulaceae, also known as burden flower, bell flower, mitral flower and so on. It is distributed in most provinces and autonomous regions of my country, and also in North Korea, Japan, and the Russian Far East. Platycodon grandiflorum is a dual-purpose resource for medicine and food, with a history of hundreds of years of application. Modern research shows that Bellflower has various pharmacological activities such as anti-inflammation, expectorant, immune regulation...
