Embodiment 1

[0019] The active ingredient flavonoids extracted from the fruit of Copperhammer japonica, which is prepared by the following method:

[0020] S1: Wash and dry the collected scalloped scalloped grass fruit, fix them at 105°C for 10 minutes, and then dry them in a drying oven at 65°C to constant weight, then crush them and pass through a 60-mesh sieve to obtain scalloped scalloped scalloped fruit powder ;

[0021] S2: Accurately weigh 1.00g of the fruit powder of Cucumis japonica, add 50% ethanol at a ratio of 1:15 and let it stand overnight;

[0022] S3: reflux extraction of the drug treated in step S2 at a temperature of 50° C. for 20 minutes;

[0023] S4: Collect the filtrate and place it in a volumetric flask to obtain an extract of the effective components of Scallopedia japonica.

[0024] After taking a certain volume of sample solution and diluting it properly, measure its absorbance according to the sodium nitrite-aluminum nitrate-sodium hydroxide colorimetric method....

Abstract

The invention relates to a pratia nummularia extract effective component extraction process. The pratia nummularia extract effective component extraction process mainly comprises: S1, washing collected pratia nummularia fruits, airing, carrying out fixation for 10 min at a temperature of 105 DEG C, drying in a drying box at a temperature of 65 DEG C to a constant weight, and crushing into powder; S2, adding the powder prepared in the step S1 into ethanol with the concentration of 50-70% according to the ratio of 1: 15-1: 25, and standing overnight; S3, performing reflux extraction on the medicine treated in the step S2 at the temperature of 50-70 DEG C for 20-80 min; and S4, collecting the filtrate, and placing the filtrate in a volumetric flask to obtain an extract of effective components of the pratia nummularia. The flavone in the pratia nummularia fruits can be effectively prepared through the steps.

Description

technical field [0001] The invention relates to an extraction process of a medicinal plant A. japonica, in particular to an extraction process of active components of the extract of A. japonica. Background technique [0002] Copper Hammer Jade Ribbon ( Pratia begoniifolia (Wall.) Lindl.), belonging to Campanulaceae (Campanulaceae), also known as ground eggplant grass, small copper hammer, born on the edge of a damp field, or in the shade of a mountain forest [1] . The whole herb is used for expelling wind and dampness, promoting blood circulation and detoxification, has good anti-inflammatory and analgesic effects, and can be used to treat rheumatic pain, bruises, mastitis, and unknown swelling. [0003] "Research on the Edible Development of Tongchui Yudai Grass" carried out research on the development of its fruit in the food field, "Extraction and Stability Research on the Pigment of Tonghammer Yudai Peel" carried out extraction and stability research on the pigment of ...
