Chemical profiling and biological screening with potential anti-inflammatory activity of Callisia fragrans grown in Egypt

Abstract

The ethanolic extract of Callisia fragrans aerial parts showed a significant strong in vivo anti-inflammatory and in vitro antioxidant activities with a high in vivo gastrointestinal safety profile and a very low in vitro cytotoxicity on peripheral blood mononuclear cells (PBMCs) with an IC₅₀ > 1000 μg/ml. The alcoholic extract of C. fragrans has been analysed by HPLC coupled to multiple-stage Linear Ion-Trap and Orbitrap High-Resolution mass spectrometry in negative electrospray ionisation mode (LC-ESI/LTQOrbitrap/MS/MSn). By this approach, it was possible to putatively identify 13 compounds, mainly organic acids, flavonoids, one steroid and one hydroxy-coumarin. Luteolin 6-C-glucopyranosyl-7-O-glucopyranoside, luteolin-8-C-glucopyranosyl-7-O-rhamnopyranoside, luteolin-6-C-glucoside and isoorientin 7-O-[6''-feruloyl]-glucoside were detected for the first time in C. fragrans and family Commelinaceae.
