Embodiment 1
[0052] The extraction of total flavonoids of sunflower disc of embodiment 1
[0053] 1. Drawing of standard curve
[0054] Accurately weigh 5.0 mg of standard rutin that was dried at 105°C to a constant mass, place it in a small beaker for ultrasonic dissolution, and make 10 mL of rutin standard stock solution (0.5 mg / mL). After diluting the rutin standard stock solution into the rutin standard application solution of different mass concentrations, according to the NaNO 2 -Al(NO 3 ) 3 method, adding 5% (mass fraction) NaNO 2 Solution 1.0mL, let stand for 6min, then add 10% (mass fraction) Al(NO 3 ) 3Solution 1.0mL, mix well, let stand for 6min. Add 8.0 mL of 4% (mass fraction) NaOH solution and let stand for 15 min. Add distilled water to make up to volume, and mix thoroughly to obtain rutin standard control solutions with different mass concentrations. Measure the optical density value of each concentration standard substance under the absorption wavelength of 510nm, ...
Embodiment 2
[0075] Example 2 Therapeutic effect of total flavonoids from sunflower discs on gouty arthritis
[0076] 1. Experimental animal grouping method
[0077] The experimental animals were 80 clean-grade male Wister rats, weighing 180±20 g, purchased from Changchun Yisi Experimental Animal Technology Co., Ltd., animal certificate number SCKX (Ji)-2016-0003. Adaptive culture was carried out in the first week, and then they were randomly divided into 4 groups (20 rats in each group), and the treatment was as follows:
[0078] Normal control group: continuous intragastric administration of normal saline from the second week to the third week (once a day, the volume of a single intragastric administration is 12 mL of normal saline per kilogram of body weight). Inject sterile normal saline (injection dose: 0.2mL sterile normal saline per mouse).
[0079] Model group: From the 2nd week to the 3rd week, the normal saline was administered continuously (the method was the same as that of t...
Embodiment 3
[0100] The analgesic effect of embodiment 3 total flavonoids of sunflower disc
[0101] 1. The effect of total flavonoids of sunflower disc on the writhing response of mice induced by acetic acid
[0102] The experimental animals were 80 clean-grade male mice, weighing 20±2g, purchased from Changchun Yisi Experimental Animal Technology Co., Ltd., animal certificate number SCKX (Ji)-2016-0003. Adaptive culture was carried out in the first week, and then they were randomly divided into 4 groups (20 rats in each group), and the treatment was as follows:
[0103] Normal control group: intragastric administration of normal saline for 7 consecutive days in the second week (once a day, the volume of a single intragastric administration was 12 mL of normal saline per kilogram of body weight), and 1 hour after the last administration, the mice were intraperitoneally injected with normal saline ( The injection dose is: 0.1 mL of normal saline per 10 g of body weight).
