GC-MS PROFILING, CHEMICAL CHARACTERIZATION, ANTIOXIDANT, Α-AMYLASE AND Α-GLUCOSIDASE INHIBITION OF SELECTED SEAWEEDS FROM SOUTHEAST COAST OF INDIA: AN IN VITRO APPROACH
Journal Title: Journal of Drug Delivery and Therapeutics - Year 2018, Vol 8, Issue 2
Abstract
The present study focuses on in vitro antioxidant and enzyme inhibitory activity of three different solvent extracts (Methanol, Ethyl acetate and Hexane) of 3 different seaweeds viz: Sargassum wightii, Caulerpa racemosa, and Acanthophora spicifera. The preliminary phytochemical analyses of the seaweed extracts have revealed the presence of various phytochemicals. The antioxidant activities of the seaweed extracts have shown the scavenging effect. Among the extracts, SWEA, SWME and SWHE have exerted effective antioxidant activity with the IC50 values (µg/mL) of: 32.86, 130.1 and 212.8, respectively. And similar trend of α-amylase and α-glucosidase activity/inhibitory property by seaweeds have been recorded. Hence, the ethyl acetate extract of S. wightii was subjected to gas chromatography. All the seaweed extracts were characterized through HPLC and, FTIR analyses. The GC-MS analysis of ethyl acetate extract of S. wightii showed the presence of a bioactive compound, Heptadecanoic acid that might be have been the reason for the recorded inhibitory activity. Keywords: Seaweeds, Sargassum wightii, DPPH, Column chromatography, GC-MS.
