Abstract
Reactive oxygen species or free radicals are dangerous and are responsible for innumerable diseases and disorders. They are responsible for creating oxidative stress which in turn damages cells, tissues and many macromolecules. Antioxidants are the only compounds which are capable of tackling them and most preferred and best are natural antioxidants. They can be obtained from any part of the plants but appropriate extraction technique and assay has to be used to evaluate the antioxidant potential of the plants. The plant kingdom with its huge diversity and affluent secondary metabolites, easy affordability and availability makes them most popular for discovering new antioxidant compounds. In this review, 50 medicinal plants belonging to 37 families were screened for their antioxidant properties. Detailed information is also given regarding the part and extraction technique used, assay and phytochemical content of the plants. Such screening studies are useful for further studies and may lead to discover new antioxidant compounds with better therapeutic efficacy.
