污毛粗叶木果实中低极性化学成分GC-MS分析

摘要

采用溶剂提取法从污毛粗叶木果实中提取低极性化学成分，并用气相色谱-质谱仪对果实中的低极性化学成分进行分离和鉴定，同时用面积归一法测定了各成分的相对百分含量。通过分析鉴定，确认了29种成分，占果实中低极性化学成分的82.57%，其主要成分为十六烷（6.63%）、二十碳五烯酸（5.25%）、十八碳烷（6.10%）、维生素E （7.61%）、硬脂酸甲酯（5.18%）。所鉴定的化合物多为该种植物中首次发现，为污毛粗叶木的进一步开发利用提供了科学依据。%　　The low-polarity chemical constituents were extracted from the fruit of L. hartii by solvent extract and were isolated and identified by GC-MS method. The relative contents of the chemical constituents were deter⁃mined by area normalization method. 29 compounds were detected and identified which accounted for 82.57% of total low- polarity chemical constituents. The main low- polarity chemical constituents were: Hexadecane (6.63%),Ficosane (5.25%),Octadecane (6.10%),Vitamin E (7.61%),Octadecanoic acid methyl ester (5.18%). Most compounds were found for the first time in this plant,which provided further evidence to exploit and uti⁃lize L. hartii.
