Embodiment 1

[0021] Take burdock fruit, crush it into coarse powder, add 6 times the amount of petroleum ether to soak overnight, extract under reflux for 3 hours to degrease, and filter. Add 5 times the amount of 30% ethanol to the filter residue, extract twice at 90°C, each time for 1h, filter, combine the filtrates, concentrate to a relative density of 1.00 (measured at 60°C), and spray dry (inlet air temperature is 185°C, outlet air temperature is 80°C) ℃, the atomization pressure is 0.4Mpa, the extract flow rate is 2.5L / h), and the burdock fruit extract dry powder with a water content of less than 5% is obtained.

[0022] The implementation effect is to obtain a powdery solid with a slightly bitter taste, brown color, and a yield of 10%, and there is no clogging of the nozzle and the phenomenon of powder sticking into blocks during spray drying. The extract contains arctiin, arctigenin, and pogrosin , LappaolA, Lappaol C, Lappaol F, Lappaol H, Arctignan E, β-sitosterol and carotene 10...

Embodiment 2

[0024] Take burdock fruit, crush it into coarse powder, add 6 times the amount of n-hexane to soak overnight, reflux extraction for 4 hours to degrease, and filter. Add 8 times the amount of 65% ethanol to the filter residue, extract 3 times at 90°C, each time for 2h, filter, combine the filtrates, concentrate to a relative density of 1.15 (measured at 60°C), and spray dry (inlet air temperature is 235°C, outlet air temperature is 90°C) ℃, the atomization pressure is 0.3Mpa, and the flow rate of the extract is 1.8L / h), and the dry powder of the burdock fruit extract with a water content of less than 5% is obtained.

[0025] The effect of the implementation is to obtain a powdery solid with a slightly bitter taste, brown color and a yield of 25%, and there is no clogging of the nozzle and the phenomenon of powder sticking into blocks during spray drying. The extract contains arctiin, arctigenin, and pogrosin , LappaolA, Lappaol C, Lappaol F, Lappaol H, Arctignan E, β-sitosterol...

Embodiment 3

[0027] Take burdock fruit, crush it into a coarse powder, add 7 times the amount of cyclohexane to soak overnight, extract under reflux for 6 hours to degrease, and filter. Add 10 times the amount of 95% ethanol to the filter residue, extract twice at 75°C for 3 hours each time, filter, combine the filtrates, concentrate to a relative density of 1.10 (measured at 60°C), and spray dry (inlet air temperature is 210°C, outlet air temperature is 100°C) ℃, the atomization pressure is 0.2Mpa, the extract flow rate is 1.0L / h), and the burdock fruit extract dry powder with a water content of less than 5% is obtained.

[0028] The implementation effect is to obtain a powdery solid with a slightly bitter taste, brown color, and a yield of 18%, and there is no blocking of the nozzle and the phenomenon of powder agglomeration during spray drying. The extract contains arctiin, arctigenin, and pogrosin , LappaolA, Lappaol C, Lappaol F, Lappaol H, Arctignan E, β-sitosterol and carotene 10 co...

Description

technical field [0001] The invention relates to a preparation method of the extract, in particular to a preparation method of the burdock fruit extract with hypoglycemic effect. It is used in the technical field of traditional Chinese medicine preparation. Background technique [0002] Burdock Fructus is a traditional Chinese medicine recorded in the 2000 edition of the "Chinese Pharmacopoeia". For measles, rubella, sore throat, mumps erysipelas, carbuncle sores, the dosage is 6-12g. [0003] With the improvement of living standards and the aging of the population, diabetes has become a frequently-occurring and common disease, and the incidence rate is increasing year by year. The incidence of diabetes is increasing rapidly in both developed and developing countries. Diabetes has become the third disease that seriously threatens human health after tumors and cardiovascular diseases, and is listed by WHO as one of the world's three major chronic diseases. At present, ther...
