GC-MS ANALYSIS OF FIXED OILS OF NIGELLA SATIVA SEEDS

Abstract

Objective: Gas chromatography-Mass spectrometry (GC-MS) is an analytical method that combines the features of gas-liquid chromatography and mass spectrometry to identify different substances within a test sample. Applications of GC-MS include drug detection, fire investigation, environmental analysis, explosives investigation, and identification of unknown samples.


Methods: The present study also relies on use of GC-MS for detection and interpretation of compounds present in N. sativa oil samples. Fixed oil was obtained through column chromatography of ethyl acetate fraction. The oil samples were subjected to GC-MS analysis which showed 5, 18, 12 and 20 compounds in four fixed oil samples respectively.


Results: The major components were linoleic acid, methyl ester (35.5%), oleic acid, methyl ester (15.007%), palmitic acid, methyl ester (8.208%).


Conclusion: Study concludes that in fixed oils, linoleic acid constitutes the major portion while oleic acid and palmitic acid also contributes in small quantity.

UJPR follows the most transparent and toughest ‘Advanced OPEN peer review’ system. The identity of the authors and, reviewers will be known to each other. This transparent process will help to eradicate any possible malicious/purposeful interference by any person (publishing staff, reviewer, editor, author, etc) during peer review. As a result of this unique system, all reviewers will get their due recognition and respect, once their names are published in the papers. We expect that, by publishing peer review reports with published papers, will be helpful to many authors for drafting their article according to the specifications. Auhors will remove any error of their article and they will improve their article(s) according to the previous reports displayed with published article(s). The main of it is ‘to improve the quality of a candidate manuscript’. Our reviewers check the ‘strength and weakness of a manuscript honestly’. There will increase in the perfection, and transparency.
