Embodiment 1

[0025] Example 1 Extraction of flavonoids in Saussurea bractosa

[0026] 1.1 Alcoholic extraction of snow lotus medicinal materials

[0027] Take 6 snow lotus medicinal materials and weigh them before and after powdering as follows: No. 1: 28.5g, 28.3g; No. 2: 16.3g, 16.5g; No. 3: 13.3g, 13.5g; : 23.1g, 23.2g; No. 6: 14.6g, 14.7g. The total powder: 111.9g, 10 times the amount of 70% ethanol was heated and refluxed for 3 times, each time for 1h, filtered through 8 layers of gauze, and the extracts were combined.

[0028] 1.2 Preparation of sample solution

[0029] The solvent was recovered from the extract under reduced pressure to obtain about 70 mL of the sample solution.

[0030] 2 refinement

[0031] 2.1 Use AB-8 macroporous resin (soaked in 95% ethanol for 24 hours). The inner diameter of the column is about 2.5cm, and the ratio of diameter to height is 1:10. Soak the macroporous resin in absolute ethanol for 24 hours and then wet-pack the column. Before loading the c...

Embodiment 3

[0051] Components and compatibility of embodiment 3 snow lotus flavonoids composition

[0052] It can be obtained from the analysis and identification of Example 2 that the purified snow lotus obtained by the extraction method of the present invention mainly contains 4 kinds of flavonoids, which are respectively: rutin: myristicin: isoquercitrin: luteolin-7-o -glucoside, and the weight ratio between them is 30:1:2:7.

[0053] The drug efficacy test (analgesic effect) of the flavonoid composition of embodiment 4 embodiment 3

[0054] Objective: through the therapeutic effect of the flavonoid composition of embodiment 3 on acetic acid-induced mouse pain model, evaluate the pharmacodynamics of the flavonoid composition of embodiment 3.

[0055] Method: mice are divided into 5 groups at random, are respectively model control group (7), positive drug control group, the flavonoid composition high-dose group of embodiment 3, the flavonoid composition middle-dose group of embodiment ...

Embodiment 6

[0123] In order to further prove the effect of the Saussurea flavonoids composition of the present invention, on the basis of the compatibility of the components obtained in Example 3, in Example 6, four commercially available compounds were used to compound the composition of this application, and then the efficacy test was carried out. Test process is consistent with the test process of embodiment 4 and embodiment 5, repeats no more at this, compound ratio and test result are as shown in the following table:

Abstract

The invention relates to a saussurea involucrata flavonoid composition, which is prepared from the following four components: rutin, myristyl ether, isoquercitrin and luteolin-7-o-glucoside. A large number of animal experiments prove the pharmacodynamic activity of the flavonoid composition provided by the invention, the flavonoid composition can be used for preparing various clinically applied pain relieving and pain easing medicines and arthritis treatment medicines, and compared with a Chinese patent medicine preparation prepared by directly applying saussurea involucrata, the composition has the effects of high pharmacodynamic activity, small clinical dosage, quick response, low side effect and the like. The dosage form of the medicine can be conventional tablets or capsules, and some new dosage forms of the medicine with higher absorptivity or better storability can be prepared according to the characteristics of the medicine components.

Description

technical field [0001] The invention relates to the technical field of compositions for medical use, in particular to a composition of Saussurea flavonoids and its application. Background technique [0002] Saussurea involucrata (scientific name: Saussurea involucrata (Kar. et Kir.) Sch.-Bip.), because its top is shaped like a lotus, it is named Saussurea involucrata, referred to as Saussurea involucrata. It is a perennial herb of the genus Asteraceae and Zephyr, 15-35 cm high. Rhizome thick, neck covered with many brown leaf remnants. Stem stout, glabrous. The leaves are dense, the basal leaves and stem leaves are sessile, and the leaves are elliptic or ovate-elliptic; the uppermost leaf bracts are leaf-like, membranous, light yellow, surrounding the total inflorescence, with sharp teeth on the edge. There are 10-20 inflorescence heads, densely forming a spherical total inflorescence at the top of the stem. Involucre hemispherical, 1 cm in diameter; involucre 3-4 layers...
