Abstract

Ayurvedic texts describe rejuvenate measures called Rasayana to impart biological sustenance to bodily tissues. Rasayana acting specifically on brain are called Medhya Rasayana. Brahmi is one of the most commonly practiced herbs for the same. Yet there exist a controversy regarding the exact plant species among Bacopa monnieri L. Penn (BM) and Centella asiatica (L.) Urban (CA) to be used as Brahmi in the formulations. Though the current literature available has suggested a very good nootropic potential of both the drugs, none of the studies have been carried out on comparative potential of these herbs to resolve the controversy. Free-radical scavenging potential for these plants is studied to find out their comparative efficacy. The study revealed a very good in vitro free-radical scavenging properties of aqueous and ethanolic extracts of both the plants as evidenced by FRAP, DPPH, reducing power, and antilipid peroxidation assays. It can be concluded from the studies that both the plants, although taxonomically totally different at family level, showed similar type of in vitro activities. The total phenolic and flavonoid contents also revealed a significant similarity in the two plants. The in vitro study supports the Ayurvedic concept of BM and CA having a similar potential.
