D. Suja, Dr. A. Rohini* and Dr. A. Chandramohan
ABSTRACT
For a long period of time, plants have been a valuable source of medicines. Phytochemicals like alkaloids, flavanoids, tannins, phenols are the non-nutritive, chemical compounds that occur naturally on plants and have diverse protective properties. Reactive oxygen species are formed in biological system as part of normal metabolism. To avoid damage caused by these excess ROS, plants have developed elaborate mechanism to manage them at sustainable level. Enzyme play an important role in lowering the ROS level and and avoid oxidative stress. Catalase, play vital role in combating oxidative stress. Measuring these enzymes activities provide an easy and precise way to study and understand an important part of the defense against oxidative stress.
Keywords: Phytochemicals, Reactive oxygen species, oxidative stress, alkaloids, flavanoids, tannins.
