不同生长年份巴戟天挥发性成分的比较

[目的]分析并比较不同生长年份巴戟天的挥发性成分。[方法]采用同时蒸馏萃取法提取巴戟天的挥发性成分并比较其组分及含量。[结果]15年生巴戟天的挥发性成分鉴定出46种,已鉴定化学成分占总离子流图峰面积的89.98% 10年生巴戟天的挥发性成分鉴定出19种,已鉴定化学成分占总离子流图峰面积的70.01% 6~8年生巴戟天的挥发性成分鉴定出14种,已鉴定化学成分占总离子流图峰面积的63.23%。巴戟天的挥发性成分主要包括酸类、醛类、醇类和烯烃类等。其中,有机酸类含量最高,占总挥发性成分的65.28%,十六酸占总挥发性成分的45.75%。[结论]从巴戟天的挥发性成分中鉴定出的物质随生长年份的增加而增加,其中十六酸、油酸等主要成分的含量与巴戟天的生长年份显著相关。

Comparison on the Volatile Components in Different Years Old Morinda officinalis

[Objective] The aim was to analyze and compare the volatile components in different years old Morinda officinalis.[Method] The volatile components were extracted from M.officinalis by simultaneous distillation and extraction and they and their contents were compared.[Result] Forty-six volatile components were identified from 15 years old M.officinalis,which accounted for 89.98% in the peak area of total ion chromatogram.Nineteen volatile components were identified from 10 years old M.officinalis,which accou...
