Phytochemical analysis and anti oxidant activity of white, red and black abrus precatorius l. (gunja): Comparative studies

Abstract

Objective To find the chemical and biological (Antioxidant action) variability of three verities of Gunja (Abrus precatorius L.) leaf based on its fruit colour i.e. White, Red and Black. Methods The aqueous and alcoholic extracts of all varieties were screened for phytoconstituents using preliminary chemical test, Chromatographic fingerprinting using LC-MS, possible antioxidant activities was screened by free radical scavenging activity (DPPH), FRAP inhibition method. Results The results showed that the three varieties vary little bit in their phytoconstituents. All the extract possessed antioxidant in dose dependent manner. Conclusions This study suggests that aqueous extract of leaves of red veriety of A. precatorius extracts exhibit great potential for antioxidant activity and may be useful for their nutritional and medicinal functions.
