Antiradical efficiency of 20 selected medicinal plants.
The antioxidant system of a plant comprises a group of chemicals that are highly diverse in their sources, effects and uses. These antioxidants are capable of contracting and damaging free radicals. This investigation deals with a screening and comparison of the antioxidant activities of 20 selected medicinal plants and their parts, individually and in combination with vitamins A, C or E, using the DPPH radical scavenging method. Phyllanthus emblica L., Santalum album L., Syzygium cumini L. and Trigonella foenum-graecum L. presented highly significant antiradical efficiency (AE) singly and in combination with either vitamin A, C or E. Further, Curcuma longa L., Momordica charantia L., S. cumini, T. foenum-graecum, Moringa oleifera Lam and S. album have also shown fairly significant AE in a vitamin combination dose of 0.001 mM concentration.
