Gas Chromatography-Mass spectrometry Analysis of Methanol Extracts from Marine Red Seaweed Gracilaria corticata

Abstract

The objective of the work is to analyse the methanol extract of marine red macro algae species Gracilaria corticata using Gas chromatography-Mass spectrometry (GC-MS) to reveal the presence of various secondary metabolites and bioactive compounds present in the algae and study its diverse properties. Methods: Gracilaria corticata was collected along the shore of Mandapam and was identified and authenticated. The methanol extract of the algae was prepared and analysed using GC-MS Perkin-Elmer, Clarus 680 model to reveal the various bioactive present in the algae. Results: The analysis revealed several bioactive compounds:undecane; 2-decyloxirane (2.023%); Methy n-tridecanoate;n-hexadecanoic acid (74.198%); eicosanoic acid (2.262%); nonanoic acid (2.084%); oleic acid (6.609%); oleic acid (4.156%); pentadecanoic acid (2.176%); bicycle [3.2.1] oct-3-en-2-one,3,8-dihydroxy-1-1methoxy-7-(7-methoxy-1, 3 benzodioxol-5-yl)-6-methyl-5 (2.901%);N-(5-chloro-2-hydroxyphenyl) dodecanamide (2.048%); and cholesta-8,24-dien-3-ol,4-methyl (1.542%). The bioactive compounds from methanol extract of algae after GC-MS analysis and their essential medicinal properties were studied in this research work. Conclusion: Gracilaria corticata has potential against bacteria, fungi, free radical scavenging, etc and can used in the drug discovery and development sector.
