Analysis of the Volatile Constituents of Black P. nigrum L. fruits in Hainan by Gas Chromatography-Mass Spectrometry

The water distillation-extractor was used for extracting the volatile substances of black P. nigrum L. in Hainan. The average oil yield obtained is 5.0%. Thirty-seven kinds of volatile constituents were identified by gas chromatography-mass spectrometry(GC/MS). Twenty components of the identified terpenoid made up 78.92% of the total volatile substances detected. The main constituents are careen(12.33%), limonene(8.05%), copaene (4.89%) and carophyllene(31.66%). The content of carophyllene is higher than reference value reported.
