不同生长年份巴戟天挥发性成分的比较

Comparison on the Volatile Components in Different Years Old Morinda officinalis

[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。

[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. officinolis, which accounted for 70.01% in the peak area of total ion chromatogram. Fourteen volatile componentswere identifred from 6-8 years old M. officinolis, which accounted for 63.23% in the peak area of total ion chronatogram ,THe volatile components extracted from M. officinolis mainly included acids, aldehydes, alcohols, alkenes and so on. Among them, the content of organic acid was highest, which accounted for 65.28% of volatile components. The pahnitic acid accounted for 45.75% of total volatile components . [Conclusion ] The matters identified from volatile convonents of M. officinolis increased as it grew older, in which the contents of main components such as palnmitic acid and oleie acid had significant correlation with the age of M. officinolis.
