Embodiment 1
[0022] Example 1: Extraction and Preparation of Jingdongshan Orange Total Alkaloids
[0023] Take by weighing 100g of pulverized Jingdongshan orange branches and leaves, according to the ratio of solid-liquid ratio g:mL=1:10, use methanol aqueous solution with a volume concentration of 90% for ultrasonic extraction for 30min, filter, and after repeated ultrasonic extraction of filter residue for 3 times, combine the filtrates, The extract was obtained after evaporation and concentration at 45°C; the extract was dissolved in aqueous hydrochloric acid solution with a volume concentration of 0.3%, adjusted to pH 2-3, extracted with ethyl acetate, the water layer was collected, and then ammonia water with a volume concentration of 5% was added. Adjust the pH to 9-10, then extract with ethyl acetate, collect the ethyl acetate layer, evaporate and concentrate, freeze-dry to obtain the total alkaloids of Jingdongshan orange.
Embodiment 2
[0024] Embodiment 2: Apply the method of DSS induction to establish the model of UC, observe the preventive effect of total alkaloids of Jingdongshan orange on UC through animal model experiments
[0025] 1. Establishment of UC model and experimental process
[0026] Male C57BL / 6 mice (6-8 weeks, weight 21-23g) were used as research objects, with 8 mice in each group; the extreme concentration was established by administration of 2.5% DSS (dextran sodium sulfate) for 7 consecutive days 5-aminosalicylic acid (SASP) was used as a positive drug, and the total alkaloids of Jingdongshan orange were administered to evaluate its preventive effect on UC; the mice were adapted to the standard environment for seven days after purchase, and the standard Feed for feeding. The specific experimental procedures and groups are as follows:
[0027] Negative control group (Control): normal drinking water
[0028] Model group (Model): administrated with normal saline for 10 consecutive days, ...
