Abstract

Lantana camara Linn., a noxious weed found in most places of the world has many potential aspects and has been used as folk medicines to cure several diseases. It is reported to possess antimicrobial, antioxidant, antidiabetic, anti-inflammatory, antiurolithiatic, wound healing, antifertility and cytotoxic activities. The plant leaf essential oil in the present study was obtained by hydrodistillation method and further analyzed by Gas Chromatography/Mass Spectroscopy. Twenty-two compounds were detected owing to 88.97 % of the total essential oil percent. Major compounds identified in the L. camara leaf essential oil were β-caryophyllene (24.96 %) and δ-selinene (17.46 %), while compounds with intermediate concentration were β-copaene (09.55 %), bicylogermacrene (6.69 %), β-phellandrene (6.49 %) and δ-cadinene (4.95 %). Few of the other minor compounds such as 3-carene (2.74 %), limonene (2.48 %), α-copaene (1.88 %), β-germacrene (1.88 %) and geranyl formate (1.64 %) were also identified in considerable quantities. Among the total identified compounds, 12.79 % of monoterpenes, 0.98 % of alkylbenzene, 1.64 % of fatty alcohol esters and 73.56 % of sesquiterpenes were found in the leaf essential oil of L. camara. The present investigation revealed the chemical profiling of L. camara leaf essential oil from North East India for the very first time and also highlights their applications as well as a relative analysis of the essential oil composition.

摘要

马tana丹（Lantana camara Linn）是一种在世界上大多数地方发现的有害杂草，具有许多潜在方面，并已被用作治疗多种疾病的民间药物。据报道，它具有抗微生物，抗氧化剂，抗糖尿病，抗炎，抗尿石症，伤口愈合，抗生育和细胞毒活性。本研究中的植物叶精油通过加氢蒸馏法获得，并通过气相色谱/质谱法进行进一步分析。由于总精油百分比的88.97％，检测到22种化合物。卡马拉乳杆菌中鉴定出的主要化合物叶片精油为β-石竹烯（24.96％）和δ-辛烯（17.46％），而中等浓度的化合物为β-pa烯（09.55％），双环美金mac（6.69％），β-el烯（6.49％）和δ-卡丁烯（4.95％）。还鉴定出了其他少量的次要化合物，例如3-烯（2.74％），柠檬烯（2.48％），α-异丁烯（1.88％），β-锗烯（1.88％）和香叶基甲酸（1.64％）。 。在总鉴定出的化合物中，在camara的叶香精油中发现了12.79％的单萜，0.98％的烷基苯，1.64％的脂肪醇酯和73.56％的倍半萜。本次调查揭示了Camara L. camara的化学特征 印度东北部首次生产的叶子精油，还重点介绍了它们的应用以及对精油成分的相对分析。
