Embodiment 1

[0025] Dry the stems and leaves of fresh Lissandra japonica, take 5kg of dried leaves, crush to obtain 100-mesh Lissandra japonica granules, soak the granules with 5L of water, and use a microwave countercurrent extractor to carry out microwave radiation treatment for 10 minutes, with a power of 900W, filter, and repeat Extract three times, combine and heat the filtrate to 40°C, pass through a ceramic membrane with a pore size of 0.5 μm while hot, collect the filtrate, and pass through an ultrafiltration membrane of 8,000 Daltons while maintaining the temperature, concentrate, extract and crystallize the filtrate to obtain Mountain Silver Flower Organic acids, flavonoids and saponins. The retentate that failed to filter through the ultrafiltration membrane was collected to prepare polysaccharides from Lily japonicus.

Embodiment 2

[0027] Dry the stems and leaves of fresh Lissandra japonica, take 5kg of dried leaves, crush them to obtain 90 mesh Lissandra japonica granules, soak the granules in 40L of ethanol, and use a microwave countercurrent extractor for microwave radiation treatment for 3 minutes, with a power of 900W, filter, and repeat the extraction Three times, the filtrates were combined and heated to 45°C, passed through a ceramic membrane with a pore size of 1.0 μm while hot, collected the filtrate, and passed through a 9000 Dalton ultrafiltration membrane while maintaining the temperature, the filtrate was concentrated, extracted, and crystallized to obtain the organic acids, flavonoids and saponins. The retentate that failed to filter through the ultrafiltration membrane was collected to prepare polysaccharides from Lily japonicus.

Embodiment 3

[0029] Dry the stems and leaves of fresh Lissandra japonica, take 5kg of dried leaves, crush to obtain 90-mesh Lissandra japonica granules, soak the granules in 100L of water, and use a microwave countercurrent extractor for microwave radiation treatment for 5 minutes, with a power of 900W, filter, and repeat the extraction Three times, the filtrates were combined and heated to 50°C, passed through a ceramic membrane with a pore size of 5.0 μm while hot, collected the filtrate, and passed through a 10,000 Dalton ultrafiltration membrane while maintaining the temperature, the filtrate was concentrated, extracted, and crystallized to obtain the organic acids, flavonoids and saponins. The retentate that failed to filter through the ultrafiltration membrane was collected to prepare polysaccharides from Lily japonicus.

Abstract

The invention relates to an extraction method for flos lonicerae active materials. The extraction method comprises the following steps: drying and crushing steams and leaves of flos lonicerae to prepare flos lonicerae particles; soaking the obtained flos lonicerae particles into an extraction solvent, and then carrying out microwave countercurrent extraction; collecting an extraction solution, heating and filtering the extraction solution by a ceramic membrane an then collecting filtrate A and retentate A; and filtering the obtained filtrate A with an ultra-filtration membrane, collecting filtrate B and concentrating, extracting and crystallizing the filtrate B to prepare flos lonicerae organic acid, flavonoid and saponin. The method is simple in process and convenient to operate; the extraction rate of the organic acid, the flavonoid and the saponin reaches 68.5%; and the purity reaches 83%.

Description

technical field [0001] The invention relates to a method for extracting active substances from Jasmine Japonica, in particular to a method for extracting polysaccharides, organic acids, flavonoids and saponins from Jasmine Jasmine, and belongs to the field of traditional Chinese medicine extraction. Background technique [0002] Mountain silver flower grows in wild forests in South China. Woody vines, 2-5m long. Bark yellowish brown gradually turning white, pubescent when young. Opposite leaves, oval to elliptic, 4-8cm long, 3.5-5cm wide, green above, sparsely hairy on main veins, off-white below, densely white pubescent; corolla tubular, 1.6-2cm long, Slightly pilose, white when first blooming, later turning yellow. The flowering period is from June to September, and the fruiting period is from October to November. The gray felted honeysuckle is rod-shaped and bent, 3-4.5cm long, 2mm in diameter at the upper part, 1mm in diameter at the lower part, and the surface is gr...
