【摘要】 采用同时蒸馏萃取法(SDE)从东京野茉莉的花中提取挥发性成分,并用气相色谱—质谱联用(GC-MS)技术对其化学成分进行分析鉴定.共鉴定出42种化学成分,占芳香油色谱总峰面积的77.96%;其成分的主要特征是:①酮类化合物含量较丰富,共有8种,为20.3%;②烯类化合物9种,占16.09%;③醛类、醇类和酚类化合物含量较高,其中醛类5种,占10.26%;醇类化合物10种,为8.63%;酚类化合物3种,占7.13%.④饱和键丰富的烷类化合物4种,达10.37%;⑤稀见的化合物有:醚类化合物2种(占4.25%);另外还分析到含有马鞭草烯酮、D-柠檬烯、壬醛、左旋香芹酮、4-烯丙基苯甲醚、茴香烯等稀见化合物.⑥酯类化合物常常是挥发"香气"类型的化合物,东京野茉莉的花中仅1种,占比0.93%.本文研究为东京野茉莉花的进一步开发利用提供理论基础和依据.更多还原

【Abstract】 The volatile components were extracted from Styrax tonkinensis flower by simultaneous distillation extraction(SDE) and their chemical constituents were identified by gas chromatography-mass spectrometry(GC-MS). A total of 42 chemical constituents were identified, accounting for 77.96% of the total peak area of aromatics. The main features of chemical constituents are: ① There are rich ketone compounds and up to 8 components have been identified from Styrax tonkinensis flower, accounting for 20.3% of the total peak area; ② 9 alkene components have been detected from Styrax tonkinensis flower, accounting for 16.09% of the total peak area;③ In the extract, the content of aldehyde, alcohol and phenolic compounds have a higher content. There are 5 aldehyde compounds,10 alcohol compounds and 3 phenolic compounds. Their content are 10.26%, 8.63% and 7.13%, respectively; ④ 4 alkane compounds with rich single bond have been found, accounting for 10.37%; ⑤ The rare compounds are two ether compounds(accounting for 4.25%). In the identified constituents, some rare compounds have been detected such as verbenone, D-limonene, nonanal, L-carvone, 4-allylanisole, anethole; ⑥ Di-n-butylphthalate(0.93%) is only one ester compounds in the syste. Ester compounds are often volatile "fragrance" type compounds. The research has provided the theoretical basis and basis for the further development and utilization of Styrax tonkinensis flowers.更多还原
