Influenza A virus is globally widespread, causing a large number of infections and deaths due to acute lung injury (ALI) every year. The destruction and impairment of alveolar epithelial and microvascular endothelial cell barrier functions are the key inducers of ALI and acute respiratory distress syndrome caused by influenza virus infection. Although noncoding ribonucleic acids (ncRNAs) do not encode proteins in host cells, they possess the ability of protein regulation and signal transduction.

Three new benzylphenanthrenes, named 1-(p-hydroxybenzyl)-4,7-dimethoxyphenanthrene-2-ol (1), 1-(p-hydroxybenzyl)-4,7-dimethoxyphenanthrene-2,8-diol (2), and 1-(p-hydroxybenzyl)-4,7-dimethoxyphenanthrene-2,6-diol (3), along with a known analog were isolated from tubers of Bletilla striata. The structures of these new compounds were established by means of HR-ESI-MS, 1D, and 2D NMR.
