Popis: Bulbus of Fritillaria cirrhosa D. Don (BFC) is a kind of plateau plant which can be used both as medicine and food in China. The aim of this study is to explore the effect of ethanol extract of bulbus of F. cirrhosa (BFC-EE) on pulmonary fibrosis using a bleomycin-induced pulmonary fibrosis model. The quality of BFC-EE was preliminarily evaluated through the contents of total alkaloids, imperialine, verticinone, verticine, imperialine-3-β-d-glucoside, delavine, peimisine, delavinone, yibeinoside A and ebeiedinone in BFC-EE were determined by UV–vis spectrophotometer and UHPLC-ESI-MS/MS. Biochemical analysis and histopathological observation confirmed the protective effect of BFC-EE on bleomycin-induced pulmonary fibrosis in rats. In addition, western blotting analysis showed that BFC-EE inhibited the expression of α-SMA and Collagen I in lung tissues, decreased the p-NF-κB/NF-κB ratio and upregulate the expression of IκBα protein, suggesting that BFC-EE can alleviate pulmonary fibrosis in rats through inhibiting the activation of NF-κB signaling pathway.
