【摘要】 本文采用固相微萃取、用气相-质谱联用(GC-MS)技术,测定林投叶子中挥发油及其他组分并确定了它们的相对含量。结果表明:从林投叶子提取液中分离出37个峰,共鉴定出35种化合物,其中16-贝壳杉烯含量最高,达27.75%,还含有棕榈酸,十六酸甲酯,戊二酸氢甲酯等等,此外还检测出2种同分异构体。研究研究林投化学成分,对评价其质量有积极意义。目的:分析林投叶子的成分。方法:用乙醚萃取法提取林投叶子中的化学成分,用气相-质谱联用(GC-MS)对其成分进行分析。结果:鉴定了林投叶子37个组分,并确定了其相对含量。通过分析测定结果得出,其叶子成分有贝壳杉烯,棕榈酸,十六酸甲酯,戊二酸氢甲酯等等,相似成分有酸类,脂类化合物,在低含量的成分中也有部分相同和相似成分。结论:本研究为开发利用林投资源提供了依据。更多还原

【Abstract】 The volatile oil and other compounds in Pandanus,were determined by SPME and GC—MS in this pape. Paper.The result indicates that 37 peaks was shown in the chromatogram of the volatile oil extracts in Pandanus and 35 compounds were identified from the leaves extracts of Screw -pine,among which Kaur-16-ene had the highest content(27.75%).n-Hexadecanoic acid,Hexadecanoic acid, methyl ester,Pentanedioic acid, monomethyl ester and so so,and some isomers were also found in the extracts from the leaves in it.Study the chemical constituents of the Pandanus, to evaluate the quality of positive significance. OBJECTIVE:To analyze the chemical constituents of the leaves in Pandanus. METHODS :The chemical constituent s of leaves were extracted by aether extraction and analyzed by GC-MS. RESULTS:37 chemical constituents in the leaves of Pandanus were identified and their relative content was determined. Determined by analyzing the results, the leaves of the ingredients Kaur-16-ene, n-Hexadecanoic acid, Hexadecanoic acid, methyl ester,Pentanedioic acid, monomethyl ester, similar types of ingredients are Acids, esters compounds in the composition of low-level there are many the same and similar components. CONCLUSION:This study offers theoretic basis for utilization of Pandanus.更多还原
