Abstract:
OBJECTIVETo identify and quantify the compound compositions of ether extracts of Ligustrum lucidum.
METHODAfter extracted 4 hour by Soxhlet extraction with ether, the extractive were analyzed by gas chromatography and mass spectrometry (GC-MS). Furthermore, heuristic evolving latent projection (HELP) was used to resolve the overlapping peaks to obtain the pure concentration profiles and mass spectra. Subsequently, mass spectral similarity search combining with the retention index was employed for the identification of each component.
RESULTTotally, 75 compounds were identified, accounting for 84.3% of that in the whole ether extracts of L. lucidum.
CONCLUSIONThe main compounds of L. lucidum are oleic acid, lupeol and (Z,Z) 9,12-octadecadienoic acid, whose relative content were 9.805%, 8.848%, 8.357%, respectively.
