Phytochemical constituents isolated from Silene popovii Schischk
摘要
In this work, with the aim to find new and biologically active natural compounds, the chemical content of the apolar and polar extracts (aerial part) of Silene popovii has been investigated. The obtained extracts of Silene popovii Schischk were purified by column chromatography (CC), and four compounds were isolated: one of them is a new saponin compound—silepovin (1), as well as three known secondary metabolites, 2-deoxy-α-ecdysone (2), cauloside A (3) and 20-hydroxyecdysone 22-benzoate (4). The structural elucidation of isolated compounds was performed using the 1D and 2D NMR spectroscopy analyses and LC-MS analysis, and all four structures were confirmed. For the new compound 1, an in vivo study of anti-inflammatory activity was conducted. The in vivo analysis has shown significant anti-inflammatory effects.
