[0012] Preparation of the water extract of Amaranth amaranthus: crush the dried pieces of Amaranth amaranth into coarse powder, add 10 times the amount of distilled water, decoct twice, each time for 1 hour, combine the decoction liquid, concentrate under reduced pressure in a rotary evaporator, and finally A concentrate of 1 g crude drug / ml was obtained.
Embodiment 2
[0013] Example 2 Therapeutic effect of water extract of amaranth on diarrhea, blood in stool, weight loss and colonic morphological changes in UC model rats.
[0014] 1. Animals: 60 clean-grade, healthy male SD rats, weighing 180g-200g, purchased from Shanghai Experimental Animal Center, Chinese Academy of Sciences, animal certificate number: [SYXK (Shanghai) 2002-0026]. Sixty rats were randomly divided into 6 groups, 10 rats in each group, one of which was used as the normal control group, and the remaining 5 groups were used for modeling.
[0015] 2. Preparation of UC animal model: Morris method (Morris GP, Beck PL, Herridge MS, et al. Hapten-induced model of chronic inflammation and ulceration in the rat colon. Gastroenterology1989, 96(3), 795-803.) To make the model, take the above-mentioned healthy male SD rats, fasting for 24 hours, injecting 2% pentobarbital sodium into the abdominal cavity for light anesthesia, and gently inserting a latex tube with a diameter of 2 mm ...
Embodiment 3
[0038] Example 3 Antioxidation and Anti-NO Free Radical Effects of Amaranth Water Extract
[0039] 1. Animals: healthy male SD rats, weighing 180--200g
[0040] 2. Drugs: Amaranth water extract is the test drug; SASP is the treatment control drug
[0041] 3. Animal grouping and administration: the animals were randomly divided into four groups, with 10 animals in each group. One group was randomly selected as the normal control group, and the other three groups were modeled with TNBS (the same method as before).
[0042] Group 1 is the normal control group: intragastric administration of normal saline every day.
[0043] The second group is the model control group: intragastric administration of normal saline every day.
[0044] The third group is the middle dose group of the water extract of amaranth: 6.5 g crude drug / kg body weight of the water extract of amaranth is gavaged every day.
