Antioxidant Assay of Bryophyllum gastonis bonnieri at Salt Stress

Abstract

Bryophyllum gastonis bonnieri is a folk medicine as it consists of many antioxidants that protects against oxidative damage, and include compounds to remove or repair damaged molecules. The work is carried out for qualitative and quantitative phytochemical responses of plant to salt stress. When the plant is subjected to various strengths of NaCl (0, 25, 50, 75 & 100 mM) the growth of the plant is reduced due to stress induced. In salinity stress the plants responses by the accumulation of enzymatic antioxidants which react against the free radicals produced (Kanika Patel et al, 2011). Bryophyllum gastonis bonnieri subjected to 7, 14, 21 and 28 days of salt stress has shown reduction in heightening of plant, amount of leaves and relative growth rate was reduced with increased in sodium chloride treatments. During salinity stress free radical level increased dramatically resulting in oxidative damage to cells. The plant overcame this damage by increased accumulation of antioxidants which neutralize free radicals.
