[0009] Preparation Example 1: Preparation of Dipsacus saponin X

[0010] Take 1 kg of Dipsacus chuanxiong medicinal material, crush it, pass through a 10-mesh sieve, add 10 times the amount (V / W) of 70% ethanol to soak overnight, reflux extraction twice, each time for 2 hours, filter the extract, and recover the ethanol until it is free. Add water to form a suspension, extract 3 times with n-butanol, combine the lower aqueous layer, apply the sample to the treated D101 macroporous resin (the weight ratio of resin to medicinal material is 1:1), wash 3 column volumes with water, discard Go, then elute 3 column volumes with 30% ethanol, discard, and finally wash 3 column volumes with 50% ethanol, collect the 50% ethanol eluate, concentrate, decolorize with activated carbon, and recrystallize to obtain a content of 98%. Dipsacus saponin X6.5g.

Abstract

The invention provides a new application of radix dipsaci saponin X in the preparation of medicines, and particularly relates to an application of the radix dipsaci saponin X in the inhibition of occurrence and development of pulmonary fibrosis by inhibiting epithelial intercellular substance transition and fibroblast proliferation so as to prevent or treat pulmonary fibrosis. In the application, the dosage of the radix dipsaci saponin X is in the range of 50-2000mg, preferably 50-1000mg.

Description

technical field [0001] The present invention relates to Dipsacus saponin X inhibiting the occurrence and development of pulmonary fibrosis so as to prevent or treat pulmonary fibrosis; specifically, Dipsacapsaponin X inhibits pulmonary fibrosis by inhibiting epithelial-mesenchymal transition (EMT) and inhibiting abnormal activation of pulmonary fibroblasts. The occurrence and development of fibrosis can 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 leads to the destruction of normal lung tiss...
