1.  Free Radical Scavenging Activity of Majorana hortensis leaves 
Ancient Science of Life  2011;30(4):96-99.
Antioxidants are an essential defense mechanism to protect our body against free radical damage. They balance the production of free radicals and detoxify them when in excess. The objective of the study is to determine the free radical scavenging potential of the candidate plant leaves when subjected to a battery of free radical scavenging assays. The different leaf extracts used were aqueous, methanol and chloroform. The results suggest that Majorana hortensis (L.) H. Karst leaves could serve as a potential source of antioxidant and can be used in any preparation for combating free radical mediated damage to the body.

2.  A study on the levels of nonenzymic antioxidants in the leaves and flowers of Clitoria ternatea 
Ancient Science of Life  2008;27(4):28-32.
Antioxidants are substances that inhibit oxidation and thus prevent cell damage. The objective of the study was to determine the antioxidant activity of the leaves as well as blue and white flowers of Clitoria ternatea. They exhibited significant antioxidant activity and the sample from the blue flower bearing plant showed better scavenging activity. The results show that Clitoria ternatea can be used as a potential antioxidant and can be used to prevent oxidative damage.

Antioxidants are the essential defense mechanism to protect the body against free radical damage. The objective of the study was to investigate the in vitro antioxidant activity of different parts of Withania somnifera (leaves, fresh tubers and dry tubers) towards free radical DPPH and the extent of inhibition of lipid peroxidation using hydrogen peroxide as prooxidant. The plant extracts exhibited significant antioxidant effect in the order as follows: leaves>fresh tubers>dry tubers. The results suggested that Withania somnifera could be a potential source of antioxidants and may be used in preparations to combat free radical mediated damage.
