Estimation of Antioxidant Activity in Costus igneus Leaf Extracts by Using Phosphomolybdenum Assay
Main Article Content
Abstract
Costus igneus, commonly known as the insulin plant, is a Spiral Flag member belongs to the family Costaceae. It usually grows as an ornamental plant in southern India, and its leaves are used as a dietary supplement in the treatment of diabetes mellitus. It has been traditionally reported for its anti-diabetic, anti-inflammatory, anti-proliferative, anti-urolithiasis, hypolipidemic, neuroprotective, and anti-microbial activity. The study was aimed to investigate the antioxidant activity in Costus igneus leaf extracts. Among the samples, the standard shows the highest rate of antioxidant activity followed by Costus igneus than other samples. The results obtained indicated a real good potential of antioxidant property in C. igneus which paved the way for newer useful drugs.
