An oraganic extract of the powdered leaves was analysed for the photosensitive compounds. Al least six different photosensitive compounds.Al least six different photosensitive components were detected in the TLC chromatogram of the extract. Two of the most photosensitive components were purified compounds into two different purifed plasmid DNAs were observed. In addition, photoreacted DNA samples were easily fragmented by heat treatment in comparision to control samples not treated with the furocoumarins. https://acta.tums.ac.ir/index.php/acta/article/view/2478 https://acta.tums.ac.ir/index.php/acta/article/download/2478/2466
