Embodiment 1

[0033] The extraction method of phenolamide I is characterized in that comprising the steps:

[0034] (1) take the dry persistent calyx and I fruit (4.5kg) of pseudophysalis as raw materials, add a volume fraction of 12 mass times of raw materials and be 70% ethanol aqueous solution, reflux extraction 2 times, extract 2 hours each time, merge to obtain the extract, Recover solvent under reduced pressure, obtain total extract (550g) after concentrating;

[0035] (2) Disperse the total extract into 5 times by mass of water, extract with sherwood oil and ethyl acetate successively, and recover the solvent under reduced pressure from the ethyl acetate extract to obtain the ethyl acetate layer extract (102g);

[0036] (3) The extract from the ethyl acetate layer was separated by silica gel column chromatography, and the dichloride dichlorides with volume ratios of 100:1, 100:2, 100:5, 100:10, 5:1, 2:1 and 1:1 were respectively Gradient elution with methane-methanol as the eluent t...

Embodiment 2

[0049] The extraction method of phenolamide I comprises the steps:

[0050] (1) Use the dried calyx and fruit of Physalis pseudophysalis as raw materials, add 80% ethanol aqueous solution with a volume fraction of 8 mass times of the raw materials, reflux extraction twice, extract for 2 hours each time, combine to obtain the extract, and recover the solvent under reduced pressure, Obtain the total extract after concentration;

[0051] (2) Disperse the total extract into water of 5 times by mass, extract with equal volumes of petroleum ether and ethyl acetate successively, and recover the solvent under reduced pressure from the ethyl acetate extract to obtain the ethyl acetate layer extract;

[0052] (3)-(6) are the same as embodiment 1(3)-(6).

Embodiment 3

[0054] The extraction method of phenolamide I comprises the steps:

[0055] (1) Use the dried calyx and fruit of Physalis pseudophysalis as raw materials, add 10 mass times of raw materials with a volume fraction of 60% ethanol aqueous solution, reflux extraction for 3 times, extract for 2 hours each time, combine to obtain the extract, and recover the solvent under reduced pressure, Obtain the total extract after concentration;

[0056] (2) Disperse the total extract into 10 mass times of water, extract with equal volumes of petroleum ether and ethyl acetate successively, and recover the solvent under reduced pressure from the ethyl acetate extract to obtain the ethyl acetate layer extract;

[0057] (3)-(6) are the same as embodiment 1(3)-(6).

Description

technical field [0001] The invention relates to the field of traditional Chinese medicine extraction, and relates to a phenolamide I, an extraction method and application thereof. Background technique [0002] Nicandra physaloides (Nicandra physaloides) is an annual herbaceous plant belonging to the family Solanaceae. It is native to Peru. In my country, it is mainly distributed in Yunnan, Guangxi and other places, and it is also cultivated in Guizhou. Pseudophysalis is a kind of Chinese herbal medicine with both medicinal and edible properties. The whole plant has sedative, expectorant, heat-clearing, detoxifying, and cough-relieving effects, and can treat mental illness, rabies, colds, rheumatism, scabies and other diseases. The seeds are used as medicine, called pseudophysalis seeds, which have the effects of clearing heat and annealing, diuretic, expelling wind, and anti-inflammatory, and can treat fever, rheumatoid arthritis, sores, carbuncles, swelling and pain. The ...
