Embodiment 1
[0017] Embodiment 1 acute toxicity test
[0018] Due to the limitation of administration concentration and administration volume, the LD50 of intragastric administration to mice could not be measured, and the water suspension, water extract, ethanol extract, and methanol extract of compound sequence Ligwu herb were pulverized at 90ml / kg dose was given to mice for intragastric administration, the animals were in good condition, and no acute toxic reaction was seen. The maximum dose of intragastric administration for mice in one day was ≥ 90ml (four kinds of extracts were respectively equivalent to crude drug amounts of 95.5g / kg, 110.5g / kg, 130.0g / kg, 135.0g / kg).
Embodiment 2
[0019] Example 2: The application of Ligularia complex to prepare uric acid-lowering products
[0020] 1. Ligularia jaluensis capsule (LJC): collect Ligularia jaluensis, dry in the shade, crush to make a hard capsule preparation.
[0021] 2. Ligularia jaluensis tablet (LJT): Collect Ligularia jaluensis, dry in the shade, pulverize, ultrasonically extract with 10 times the amount of 75% ethanol three times, each time for 30 minutes, filter, combine the filtrates, and evaporate to dryness , pulverize, add appropriate amount of starch, and press into tablets.
[0022] 3. Ligularia jaluensis oral liquid (LJOL): take Ligularia jaluensis oral liquid, decoct in 10 times the amount of water for 40 minutes, filter, concentrate the filtrate to obtain liquid extract, add auxiliary materials, and make oral liquid .
