Isolation of a novel quercetin derivative from and RT-PCR-assisted probing to investigate its DNA repair in hepatoma cells.

Background And Purpose: DNA damage can lead to carcinogenesis if replication proceeds without proper repair. This study focused on the purification of a novel quercetin derivative present in fruit and studied its protective role in hepatoma cells due to HO-DNA damage.

Experimental Approach: The pure compound obtained from the silica gel column was subjected to structural characterization using spectroscopic techniques.
