UPLC ESI-PDA Msn Profiling Of Phenolics Involved In Biological Activities Of The Medicinal Plant Halocnemum Strobilaceum (Pall.)

Halocnemum strobilaceum is a halophyte present in the humid and arid bioclimatic regions of Egypt. The current study aimed at UPLC/PDA/ESI-MSn qualitative chemical profiling of the phyto-constituents underlining both antioxidant and cytotoxic activities of the bio-active fraction in comparison with the other fractions. It resulted in detection of several related compounds to prenylated flavonol icariin as a first report in this species. Results showed that ethyl acetate exhibits an appreciable antioxidant activity using in-vitro DPPH assay with percentage of 82.35% and remarkable anticancer capacity against most common types of cancer in Egypt; breast (MCF-7), human prostate (PC-3) cancer cell lines, and human lung carcinoma (A-549) with IC50 43.1± 2 µg/mL, 115±5 µg/ml, and 53.3±3 µg/mL respectively. These findings point out the appropriate solvent for extraction of the bio-phenolics with this halophyte which is a considerable source of remarkable potential secondary metabolites that exhibit original and interesting anticancer capacity.
