Chemical Constituents Analysis of Petroleum Ether Extract from Xylaria striata by GC-MS
Journal Title: Microbiology Research Journal International - Year 2017, Vol 19, Issue 5
Abstract
Aims: To analyze the chemical constituents of petroleum ether extract of Xylaria striata. Methodology: Xylaria striata was extracted by petroleum ether, and then the extract was analyzed by Gas Chromatography-Mass Spectrometer (GC-MS). Identiļ¬cation of compounds was achieved from their GC retention indices (RI) relative to n-alkanes and by computer search using libraries of NIST05, as well as comparisons of the fragmentation pattern of the mass spectra with data published in the literature. Results: Thirty-seven compounds were separated by gas chromatography. Based on the NIST spectral library and corresponding literature information, thirty compounds which covered 98.43% of the total peaks were identified. Most of them were fatty acids and their esters (77.58%), steroids (19.44%). The methyl linoleate covered 38.23% of the total peaks, while methyl palmitate was 19.12%, methyl linoleate (9-cis, 12-trans) was 5.15%, methyl oleate was 4.43% and methyl stearate was 3.3%. Conclusion: This is the first report of chemical constituents of the petroleum ether extract of Xylaria striata by GC-MS. The result will provide ample information for further exploration and utilization of Xylaria striata.
