Problems solved by technology

[0003]Modern pharmacological studies have shown that polyphenols have strong analgesic activity (Ghannadi A, J Med Food. 2005, 8(4):488-93; V Hajhashemi, Research in Pharmaceutical Science, 2007, 92-98), and Trigonum contains polyphenols such as phenylpropanoids, ketones, flavonoids, such as: ferulic acid and its glycoside derivatives, kaempferol phenol, rutin, formononetin, flavonols, trigonal diphenylide, 2,7-dihydroxyxanthone, triangular tolanin, etc. (Dong Xue et al. Qilu Pharmaceutical Affairs, 2005, 24 (10 ), 612; Dong Xue et al., Acta Pharmaceutica Sinica, 2008, 43(1):63-66; Kong Lijuan et al., Chinese Herbal Medicine, 2011,42(3):440-4442). However, the preparation method and Its analgesic activity has not been reported

Embodiment 1

[0016] Get triangular 5Kg, pulverize it, cross 40 mesh sieves, put in the extraction tank, add volume V: triangular powder weight Kg is 50% ethanol of 5:1, soak for 12 hours; The dipped triangular reflux extracts 2 times, extracting for 1 hour each time, filtering, combining the extracts, concentrating, and drying to obtain the triangular ethanol extract; dry the triangular ethanol extract onto a polyamide column, and first elute with water and 5% ethanol , then eluted with 40% ethanol, detected by polyamide thin-layer chromatography, collected the fractions eluted with 40% ethanol, concentrated, and dried under reduced pressure to obtain total trigonal phenols with a content of 50.3%.

Embodiment 2

[0018] Take 5Kg of triangular, pulverize it, pass through a 60 mesh sieve, put in the extraction tank, add volume V: triangular powder weight Kg is 50% ethanol of 5:1, soak for 12 hours; the dipped triangular reflux extracts 2 times, extracting for 1 hour each time, filtering, combining the extracts, concentrating, and drying to obtain the triangular ethanol extract; dry the triangular ethanol extract onto a polyamide column, and first elute with water and 5% ethanol , then eluted with 40% ethanol, detected by polyamide thin-layer chromatography, collected the fractions eluted with 40% ethanol, concentrated, and dried under reduced pressure to obtain the total trigonal phenols with a content of 57.8%.

Embodiment 3

[0020] Get triangular 5Kg, pulverize it, cross 80 mesh sieves, put in the extraction tank, add volume V: triangular powder weight Kg is 50% ethanol of 5:1, soak for 12 hours; The dipped triangular reflux extracts 2 times, extracting for 1 hour each time, filtering, combining the extracts, concentrating, and drying to obtain the triangular ethanol extract; dry the triangular ethanol extract onto a polyamide column, and first elute with water and 5% ethanol , and then eluted with 40% ethanol, and detected by polyamide thin-layer chromatography. The fraction eluted with 40% ethanol was collected, concentrated, and dried under reduced pressure to obtain the total trigonal phenols with a content of 53.2%.

Abstract

The invention discloses a preparation method of sparganium stoloniferum total phenols with analgesic activity. The method comprises the following steps of: grinding sparganium stoloniferum, screening with a 40 / 80-mesh screen, putting into an extraction tank, adding ethanol with the concentration between 50 percent and 95 percent, and soaking for 12 hours, wherein the ratio of the volume dose V of the ethanol to the weight Kg of the sparganium stoloniferum powder is 5-10:1; performing reflux extraction on the soaked sparganium stoloniferum 2-4 times, lasting for 1-3 hours every time, filtering, combining extracting solutions, concentrating and drying to obtain an alcohol extract of the sparganium stoloniferum; and loading the alcohol extract of the sparganium stoloniferum on a polyamide column with a dry method, eluting with water and ethanol with the concentration 5 percent respectively, eluting with ethanol with the concentration between 40 percent and 65 percent, detecting and identifying with thin layer chromatography, collecting fractions eluted with the ethanol with the concentration between 40 percent and 65 percent, concentrating and drying at reduced pressure to obtain sparganium stoloniferum total phenols, wherein the content of the total phenols is between 50 percent and 99 percent. As proved by a result of an analgesic activity test on the obtained sparganium stoloniferum total phenols with an acetic acid writhing reflex, sparganium stoloniferum total phenols have a remarkable analgesic function.

Description

Technical field [0001] The present invention belongs to the field of pharmaceuticals, involving a method of preparing a total phenol with analgesic activity from the three edges of Chinese medicine. technical background [0002] The three -edge of Chinese medicine is black triangular plants black triangular ( Sparganium Stoloniferum BUCH. — HMA.) The tubers were began to be used in the Tang Dynasty's "Materia Medica Pickling" and used it to this day. Its medicinal value has been widely affirmed.Its sexuality, flat, liver and spleen meridian have functions such as breaking blood and qi, eliminating accumulation and analgesic, which are traditional Chinese medicine.Three -edge clinical application is widely used. It is commonly used to treat tumors, hepatoboli, pain rib pain, postpartum blood stasis, pelvic inflammatory disease and other certificates.The analgesic activity of the triangular edge is obvious. With Kunming mice as the experiment, the acetic acid twisting method and th...
