Electron ionization gas chromatography-mass spectrometry (ei-gc-ms) analysis of extracted oil from Tribulus terrestris seeds..
Pak J Pharm Sci Jan ;33(6):2633-41.

The fine powdered form T. terrestris seeds, was extracted with n-hexane by soxhlet apparatus. The aim of the study was to analyze the T. terrestris seed oil (sample-A) by electron ionization Gas Chromatography-Mass Spectrometry (EI-GC-MS) using full scan method within mass range from 40-700 charge to mass ratio (m/z). Out of 102 compounds (1A-102A) 11 compounds (30A, 32A, 37A, 45A, 47A, 48A, 49A, 64A, 83A, 101A and 102A) could not be identified and 91 were identified by classical interpretation of the mass spectrum and by using NIST14 library with match factor > 95 of mass spectrums. While among the 91 identified compounds 18 were found common therefore finally 73 compounds were identified in the present EI-GC-MS analysis of sample-A.
