OBJECTIVE
This study aimed to determine the chemical profile of leaf oil.
METHODS
The essential oil was extracted from dried leaf samples using the Soxhlet extraction method. The oil was separated from the solvent and the bioactive compounds were identified using gas chromatography-mass spectroscopy (GC-MS) and Fourier transform infrared spectroscopy (FTIR). The identified peaks in the mass spectrum were matched with the database of the US National Institute of Standards and Technology (NIST) library.
RESULTS
The FT-IR results indicated the presence of alcohols, carboxylic acids, phenols, alkanes, ketones, and primary amine compounds. GC-MS identified 43 compounds representing 95% of the total leaf essential oil components. Some of the major isolated compounds included a pyrrolizine; 1-dodecanol; 1,2-nonadecanediol; phytol; 1,3-dioxolane; 4-undecene, 9-methyl, (Z)-; 1-eicosanol; and imidazole.
CONCLUSIONS
The identified constituents of the extracted oil have established pharmacologic and insecticidal activities, and these compounds are also used in the drink, food, and cosmetic industries. This extract is highly valuable for the medical treatment of various ailments.
目的
本研究旨在确定叶油的化学成分。
方法
使用索氏提取法从干燥的叶片样本中提取精油。将油从溶剂中分离出来，并用气相色谱-质谱联用（GC-MS）和傅里叶变换红外光谱（FTIR）鉴定生物活性化合物。质谱中的鉴定峰与美国国家标准与技术研究所（NIST）数据库相匹配。
结果
FT-IR 结果表明存在醇、羧酸、酚、烷烃、酮和伯胺化合物。GC-MS 鉴定出 43 种化合物，占总叶精油成分的 95%。一些主要的分离化合物包括吡咯烷；1-十二烷醇；1,2-十九烷二醇；叶绿醇；1,3-二氧戊环；4-十一烯，9-甲基，（Z）-；1-二十烷醇；和咪唑。
结论
所提取油中的鉴定成分具有药理和杀虫活性，这些化合物也用于饮料、食品和化妆品行业。这种提取物对各种疾病的治疗具有很高的价值。
