Embodiment 1

[0051] A, extract extraction: Pueraria lobata is pulverized to 20 orders, and is extracted 2 times with solvent ultrasound, and the quality of each extraction solvent used is 3 times of Radix Pueraria mass, each time 30 minutes, merges extract and filters, and filtrate is concentrated under reduced pressure to It was observed with the naked eye that there was just a precipitate, and it was left to stand for 2 hours, and the precipitate was filtered off, and then the obtained filtrate was concentrated into an extract;

[0052] B. Silica gel column chromatography: the extract is first dissolved with acetone or methanol with 1.5 times the weight of the extract, then mixed with 80 mesh silica gel with 0.8 times the weight of the extract, and then loaded for column chromatography. The silica gel is 160 mesh, and the weight of the silica gel used is 6 times the weight of the extract; the organic solvent is mixed with chloroform and acetone with a volume ratio of 1:0, 9:1, 8:2, 7:3, 1...

Embodiment 2

[0056] A, medicinal extract extraction: Pueraria lobata root is pulverized to 40 orders, is extracted 5 times with solvent ultrasound, the quality of extraction solvent used at every turn is 5 times of Radix Puerariae quality, each time 60 minutes, merges extract and filters, and filtrate is concentrated under reduced pressure to It was observed with the naked eye that there was just a precipitate, and it was left to stand for 5 hours, and the precipitate was filtered off, and then the obtained filtrate was concentrated into an extract;

[0057] B. Silica gel column chromatography: the extract is first dissolved with acetone or methanol that is 3 times the weight of the extract, then mixed with 100 mesh silica gel that is 1.2 times the weight of the extract, and then loaded for column chromatography. The silica gel is 200 mesh, and the weight of the silica gel used is 10 times the weight of the extract; the organic solvent is mixed with chloroform and acetone with a volume rati...

Embodiment 3

[0061] A, extract extraction: Pueraria root is pulverized to 30 order, extracts 4 times with solvent ultrasound, the quality of extraction solvent used at every turn is 4 times of Radix Pueraria mass, 45 minutes each time, merges extract and filters, and filtrate is concentrated under reduced pressure to It was observed with the naked eye that there was just a precipitate, and it was left to stand for 3 hours, and the precipitate was filtered off, and then the obtained filtrate was concentrated into an extract;

[0062] B. Silica gel column chromatography: the extract is first dissolved with acetone or methanol twice the weight of the extract, then mixed with 90-mesh silica gel that is twice the weight of the extract, and then loaded for column chromatography. The silica gel is 180 mesh, and the weight of the silica gel used is 8 times the weight of the extract; the organic solvent is mixed with chloroform and acetone with a volume ratio of 1:0, 9:1, 8:2, 7:3, 1:1, 3:7 For gra...

Abstract

The invention relates to an isoflavone compound capable of prolonging the quality guarantee period of tobacco absolute oil as well as a preparation method for the isoflavone compound and application of the isoflavone compound, and belongs to the technical field of plant chemical technology. The isoflavone compound is separated from traditional Chinese medicine radix pueraiae which is medicinal and edible plant, the compound is named as 4'-hodraxy-7-hydroxymethyl-6-methoxy-isoflavone, a molecular formula of the compound is C17H14O5, and a structural formula of the compound as shown in formula (I): the formula (I) is described in the description. A preparation method for the isoflavone compound comprises the following steps: performing extract extraction, performing column chromatography on silica gel and performing efficient liquid-phase chromatographic separation. Anti-oxidation active screening is performed on the compound, and the experimental results are that the compound displays relatively strong oxidization resistance, and has good effect of prolonging the quality guarantee period of the tobacco absolute oil. According to cigarette sensory evaluation results, the added compound does not affect cigarette suction quality, and is an ideal tobacco absolute oil anti-oxidant.

Description

technical field [0001] The invention belongs to the technical field of phytochemistry, and specifically relates to an isoflavone compound extracted for the first time from Pueraria root, a traditional medicine and food homologous plant, and an extraction method thereof. At the same time, the compound of the invention has good antioxidant activity and can be used as tobacco The antioxidant of the absolute can significantly prolong the shelf life of the tobacco absolute. Background technique [0002] Pueraria lobata is the root tuber of the leguminous plant Pueraria mirifica or Pueraria vine. It is distributed in most parts of the country except Xinjiang and Tibet. Pueraria vine is cultivated or wild in mountain shrubs and sparse forests. It is distributed in Guangdong, Guangxi, Hunan, Jiangxi and other places. Pueraria lobata is a kind of commonly eaten vegetable in some provinces and regions in southern my country. It tastes sweet, cool and delicious. It is often used for s...
