[0010] Preparation Example 1: Preparation of palm cyanidin

[0011] 1kg of dried Artemisia argyi leaves was crushed, heated and refluxed with 6 times the amount of 95% ethanol for 3 times, each time for 6 hours, filtered, combined the filtrate, concentrated under reduced pressure to extract the extract, added an appropriate amount of distilled water to suspend, and dissolved in 10L Extract with ethyl acetate in a separatory funnel, collect the extract and separate it with silica gel column chromatography (silica gel 600g, 300-400 mesh), and use CH2Cl2→CH2Cl2:EtoAc (5:1→2:1)→EtoAc→MeOH in sequence Gradient elution, combined similar components by TLC, and passed through a silica gel column with normal pressure to obtain 460 mg of palmicyanidin.

Abstract

The invention provides novel pharmaceutical purposes of jaceosidin and specifically relates to application of jaceosidin in prevention or treatment of pulmonary fibrosis, wherein through inhibition of pulmonary epithelial-mesenchymal transition, pulmonary vascular endothelial-mesenchymal transition and propagation of fibroblasts, growth and development of pulmonary fibrosis are inhibited, so prevention or treatment of pulmonary fibrosis is realized. In the above-mentioned application, the dosage range of applied jaceosidin is 20 to 1000 mg, preferably, 20 to 500 mg.

Description

technical field [0001] The invention relates to palm cyanidin inhibiting the occurrence and development of pulmonary fibrosis so as to prevent or treat pulmonary fibrosis; specifically, palm cyanidin inhibits lung epithelial cell-mesenchymal transition and pulmonary vascular endothelial cell-mesenchymal transition, inhibits The abnormal activation of pulmonary fibroblasts can inhibit the occurrence and development of pulmonary fibrosis, so as to prevent or treat pulmonary fibrosis. Background technique: [0002] Idiopathic pulmonary fibrosis (IPF), also known as cryptogenic fibrosing alveolitis (CFA), is a chronic inflammatory interstitial disease. (usual interstitialpneumonia, UIP) is a characteristic pathological change with unknown etiology. The main manifestations are that the appearance of fibroblastic foci leads to the deposition of a large amount of extracellular matrix (ECM), the accumulation of collagen, and the destruction of alveolar structure, which eventually l...
