Protective role of Monotheca buxifolia and Bosea amherstiana against H2O2 -induced DNA damage in human lymphocytes and its effect on oxidative enzymes.

Experimental based evidence suggests that most of the medicinal plants possess a wide-ranging pharmacological and biological activity that may possibly protect tissues against O2-induced damages. The objectives of the current study are: first, to investigate the effects of Monotheca buxifolia and Bosea amherstiana on H2O2 induced DNA damage in human lymphocytes and second, to determine its effect on oxidative enzymes. Cells were treated at concentration of 100μg/mL with both plants. Alkaline Single Cell Gel Electrophoresis/comet assay were used for DNA damage analysis. Activities of antioxidant enzymes TBARS, SOD, CAT and POD were assayed on treatment with the extracts. Both plants species possess the protective role against H2O2-induced lymphocytes DNA. Dichloromethane (DCM) fraction of Monotheca buxifolia (H DNA 94.79±0.29%) and methanolic fraction of Bosea amherstiana (H DNA 93.63±2.23%) possess high protection Significantly decrease occur in status of antioxidant enzymes. This study indicates that both plants have potential in preventing oxidative damages/stress related diseases and would be suitably used as supplements in combination with conventional drug for the treatment of cancer like diseases.
