Embodiment 1

[0010] Example 1 Preparation of rosmarinic acid freeze-dried powder for injection

[0011] Take 50.0g of rosmarinic acid, add 2000ml of water for injection to dissolve it, adjust the pH to 5.5-7.5 with NaOH, add 8g of mannitol, stir to dissolve, ultra-filter to obtain a pyrogen-free clear solution, pour it into a 10ml vial, 2ml / piece, freeze-dried according to the freeze-dried powder injection process to make each freeze-dried powder injection containing 50.0mg of rosmarinic acid.

Embodiment 2

[0012] Example 2 Preparation of Rosmarinic Acid Tablets

[0013] prescription:

[0014] Rosmarinic acid 100.0g

[0015] Powdered sugar 35.0g

[0016] Lactose 40.0g

[0017] Sodium carboxymethyl starch 23.0g

Description

technical field [0001] The invention relates to a new application of medicine, in particular to the application of rosmarinic acid in the preparation of medicines for preventing or treating liver fibrosis and kidney fibrosis. Background technique: [0002] Liver fibrosis is an important pathological feature of chronic liver disease. Viruses, ethanol, autoimmune diseases and other etiologies can cause liver cell necrosis, regeneration and persistent fibrous proliferation, eventually leading to cirrhosis. It has been confirmed that liver fibrosis is a reversible disease, while liver cirrhosis is irreversible. Therefore, in the treatment of chronic liver disease, the prevention and treatment of liver fibrosis plays an important role. [0003] Renal fibrosis (including renal interstitial fibrosis and glomerulosclerosis) is the main pathological basis of the final stage of renal damage caused by various reasons. The proliferation and activation of stromal cells are related to ...
