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

Gas chromatography-mass spectrometry analysis of various organic extracts of Merremia borneensis from Sabah.

OBJECTIVE To analyse the chemical composition of different extracts of Merremia borneensis (M. borneensis) by gas chromatography-mass spectrometry (GC-MS). METHODS The dried leaves powder was extracted with methanol at room temperature by using Soxhlet extractor. Methanol crude extracts of M. borneensis were extrastel with hexane, chloroform, ethyl acetate and butanol. RESULTS Qualitative a...

Gas Chromatography-Mass Spectrometry

Gas chromatography (GC) is a widely applied technique in many branches of science and technology. For over half a century, GC has played a fundamental role in determining how many components and in what proportion they exist in a mixture. However, the ability to establish the nature and chemical structure of these separated and quantified compounds is ambiguous and reduced, and requires a spect...
