摘要
Abstract
Objective To study the chemical constituents and relevant content of essential oil from a Tibetan herb-Bibilin (Piper longum L. ) , which was usually considered as one of "three pungent herbs". Methods The essential oil from Bibilin was extracted by using supercritical CO2 fluid extraction, the chemical constituents were separated and identified and their relevant content was determined by using gas chromatography-mass spectrometry ( GC-MS). Results The yield of the essential oil was 9. 7%. There were 59 peaks separated and 52 constituents identified. The main constituents were piperylpiperidine (19.24% ), cubebene (10.62% ), 4-nitrophenyl o-anisic ester (6.47% ), l-( 1-oxo-11, 14-eicosadienyl)-pyrrolidine (4.75%), E-14-hexadecenal (4.38%), n-pentadecane (4.35%) and trans-methyl linolelaidate (4.28% ). ConclusionThe essential oil extracted by supercritical CO2 fluid extraction is one of effective components of Bibilin, which is the major material base of its pungent flavor.关键词
