Embodiment 1

[0018] Crush the non-mildew and dry Pang Hai into powder of 40-50 mesh size; condense and reflux in petroleum ether at 50°C for 2.5 hours, repeat twice for degreasing, and dry the material; dry the degreased dry material at 80 Condensate and reflux in % ethanol for 2.5h, repeat twice to remove small molecular substances such as monosaccharides, polyphenols, oligosaccharides and glycosides and passivate endogenous enzymes, evaporate the solvent on the raw materials; add 75 times the weight of water Soak the pretreated raw materials, select ultrasonic power of 60W, and ultrasonically treat the material for 15 minutes; heat the above-mentioned liquid to 65°C, stir and extract continuously for 1.5 hours, centrifuge at 3500 rpm for 10 minutes in a centrifuge, and the supernatant Suspended swollen gums in the liquid are suction-filtered with 200-mesh nylon cloth, and the sediment and insoluble matter are added with water 25 times the weight of the raw material, extracted in a 65°C wa...

Embodiment 2

[0020] Condensate and reflux Pandahai powder in petroleum ether at 60°C for 2 hours, repeat twice to degrease, and dry the material; condense and reflux the dried material after degreasing in 85% ethanol for 2 hours, repeat twice, and evaporate the solvent on the raw material ; Add 70 times the weight of water to soak the pretreated raw materials, select a power of 50W ultrasonic, and ultrasonically treat the material for 15 minutes; heat the above-mentioned material liquid to 60 ° C, continuously stir and extract for 2.0 hours, and pass it through a centrifuge at 3500 rpm Centrifuge for 10 minutes under the same conditions, and the swollen glue suspended in the supernatant is filtered with 200-mesh nylon cloth. The sediment and insoluble matter are added with water 25 times the weight of the raw material, and extracted in a water bath at 60°C for 1.5 hours, similar to the first time. Centrifugal filtration and nylon cloth suction filtration, combined two suction filtrates; Con...

Embodiment 3

[0022]Condensate Pandahai powder in petroleum ether at 30°C for 3 hours, repeat twice to degrease, and dry the material; condense the dried material after degreasing in 80% ethanol for 3 hours, repeat twice, and evaporate the solvent on the raw material ; Add 80 times the weight of water to soak the pretreated raw materials, select a power of 60W ultrasonic, and ultrasonically treat the material for 10 minutes; heat the above-mentioned material liquid to 55 ° C, continuously stir and extract for 2.0 hours, and pass it through a centrifuge at 3500 rpm Centrifuge for 10 minutes under the same conditions, and the swollen glue suspended in the supernatant is filtered with 200-mesh nylon cloth. The sediment and insoluble matter are added with water 25 times the weight of the raw material, extracted in a water bath at 55°C for 1.5 hours, and carried out similarly to the first The centrifugal filtration and nylon cloth suction filtration, combined the two suction filtrates; concentrat...

Abstract

The invention discloses a Pangdahai polyoses and a preparation method thereof. The method comprises Pangdahai materials which are degreased and pretreated by ethanol are added with water to be treated by ultrasonication, and then is heated up to 55-65 DEG C to be extracted; after that the extracting solution is concentrated, processed by ethanol precipitation and purified according to the conventional method. By adopting ultrasonication and water bath extraction with lower temperature, the obtained Pangdahai water soluble polyoses has higher yield and purity as well as better anti-inflammation activity.

Description

technical field [0001] The invention relates to the field of purification of traditional Chinese medicines, in particular to a sea polysaccharide and its preparation method and application. Background technique [0002] Semen Sterculiae Lychnophera (Semen Sterculiae Lychnophera) is the dry and mature seed of Sterculiae Lychnophera. It is a traditional Chinese medicinal material for clearing and moisturizing the throat. Traditional Chinese medicine believes that it has the effects of clearing away heat and nourishing the lungs, relieving throat and detoxification, moistening the intestines and laxative. Hoarseness and heat knot constipation embolism. Plastid sea polysaccharide is one of the main ingredients in puffy sea. Chen Jianmin et al. (Chen Jianmin, Cao Peirang, Song Hongtao. Purification and properties of polysaccharide PPIII from Panghaihaimae [J]. Chinese Journal of Traditional Chinese Medicine, 1996, 21 (1): 39-41) reported the use of boiling water (100 ° C) to ex...
