Embodiment Construction

[0009] Weigh rosmarinic acid in a volumetric flask, dissolve and dilute in 50% ethanol, and shake well; weigh the mint phenolic acid extract, put it in a volumetric flask, dissolve and dilute in 50% ethanol, and shake well; absorb rosmarinic acid solution , put it in a volumetric flask, add 50% ethanol, 0.1-0.3% SDS solution, and mixed developer in sequence, shake well, and let it stand in the dark for 5 minutes; add 0.1 mol·L -1 Dilute with hydrochloric acid solution, shake well, and stand for 60 minutes; take mint medicinal materials, add 16 times the amount of 30% ethanol to extract 3 times, each time for 1.5 hours, combine the ethanol extracts, and recover the solvent under reduced pressure to obtain the extract.

[0010] The mixed developer is prepared by volume ratio of 0.6% potassium ferricyanide solution and 0.9% ferric chloride solution.

[0011] The addition amount of described SDS solution is 0.2%.

[0012] The present invention can be accomplished using the fol...

Abstract

The invention relates to a macroporous adsorption resin purification process for total phenolic acid of mint, belonging to the technical field of purification processes. The purification process provided by the invention has the advantages of a good purification effect, simple operation and good repeatability. According to a technical scheme in the invention, the process comprises the following steps: weighing rosmarinic acid, putting rosmarinic acid into a volumetric flask, dissolving rosmarinic acid with 50% ethanol and carrying out dilution and shaking up; weighing a mint phenolic acid extract, putting the mint phenolic acid extract into another volumetric flask, dissolving the mint phenolic acid extract with 50% ethanol and carrying out dilution and shaking up; sucking up the rosmarinic acid solution, putting the rosmarinic acid solution into a volumetric flask, successively adding 50% ethanol, 0.1 to 0.3% SDS solution and a mixed color developing agent, carrying out shaking up and standing an obtained mixture in the dark for 5 min; adding a hydrochloride solution with a concentration of 0.1 mol / L for dilution, carrying out shaking up and carrying out standing for 60 min; and taking herbal mint, adding 16 times volume of 30% alcohol, carrying out extraction 3 times, each time lasting 1.5 h, combining ethanol extracts and carrying out pressure reduction to recover a solvent so as to obtain the extract.

Description

technical field [0001] The invention belongs to the technical field of purification process, and in particular relates to a purification process of mint total phenolic acid macroporous adsorption resin. Background technique [0002] Mint is the dry aerial part of the Lamiaceae plant. It is a traditional pungent and cool-relieving medicine. It has a pungent taste and a cool nature. Peppermint mainly contains chemical components such as volatile oil, flavonoids, terpenoids, and phenolic acids, among which phenolic acids include caffeic acid, rosmarinic acid, cis salvianolic acid, trans salvianolic acid J, shikonian acid, Salvianolic acid B, danshensu, syringic acid, vanillic acid, protocatechuic acid and other components are important medicinal ingredients in peppermint, which have good anti-respiratory syncytial virus (RSV) effect. Due to its advantages of high reusability, low price, and various types, macroporous adsorption resins are often used in the purification and pre...
