海南地区白胡椒挥发油成分的研究

Analysis of Volatile Oil from Piper Nigrum L. in Hainan Province

用同时蒸馏萃取方法对海南地区白胡椒中挥发油组分进行了提取 ,测得白胡椒挥发油质量分数为5 5 % ,并用GC MS法对挥发油进行了分离和鉴定 ,确认出 2 5种化合物 ;用峰面积归一法通过G170 1BA化学工作站数据处理系统得出各化学成分在挥发油中的峰面积相对质量分数为 80 6 %

The method of simultaneous distillation _extraction is employed to extract the volatile oil of piper nigrum L. from Hainan Province.The yield of the volatile oil is 5 5%.GC/MS method is applied to determine the chemical constituents of the volatile oil,25 compounds were identified.The percent contents of the chemical components identified are obtained by G1701BA Chemstation.
