ABSTRACT

To determine and compare total antioxidant activity (TAA) and phenolic content (TPC) of Sansevieria trifasciata leaves’ extract with different fruits’ extract (Guava, Indian plum and Indian gooseberry) and fruit juices (Pomelo, Orange, and Beetroot) on the basis of two extraction methods, total phenolic content and antioxidant activity were analysed by Folin-Ciocalteu’s and Phosphomolybdate assay, respectively and expressed as equivalent to catechin. The extraction process of selected samples was done by using both decoction extraction method (DEM) and microwave-assisted method (MAE) of water solvent. Among both techniques of extractions, MAE exhibited significantly higher TPC and TAA than DEM. Compared to Sansevieria trifasciata plant extracts, there was a strong positive correlation coefficient (á<0.05) between the total phenolic contents and antioxidant activities of different fruit juices and fruit extracts in both the classical (DEM) and modern (MAE) techniques. Sansevieria trifasciata possesses a considerable amount of phenolic compounds and antioxidant activity concerning different fruit juices and fruit extracts which directly associated with health-promoting potential and appears as possible drug development for antioxidant. Among all extract and juices, Indian gooseberry possesses the greatest total phenolic content and antioxidant activity due to its higher TPC.

Key words : Antioxidant activity, Citrus fruits, Decoction extraction method (DEM), Microwave-assisted extraction (MAE), Polyphenols, Sansevieria trifasciata.
