Phytochemical Composition and Antimicrobial Activity of Essential Oil from the Leaves of L.

is an enormously useful aromatic plant known for its insecticidal, antifungal, parasiticidal, and medicinal values. The main aim of this study is to investigate phytochemical contents and the potential antimicrobial activities of essential oil (AVEO) from the fresh leaves of grown in Manipur. The AVEO isolated by hydro-distillation from were analyzed by gas chromatography/mass spectrometry and solid-phase microextraction-GC/MS to describe their volatile chemical profile. There were 47 components identified in the AVEO by GC/MS, amounting to 97.66% of the total composition, while 97.35% were identified by SPME-GC/MS. The prominent compounds present in AVEO analyzed by direct injection and SPME methods are found to be eucalyptol (29.91% and 43.70%), sabinene (8.44% and 8.86%), endo-Borneol (8.24% and 4.76%), 2,7-Dimethyl-2,6-octadien-4-ol (6.76% and 4.24%), and 10-epi-γ-Eudesmol (6.50% and 3.09%). The consolidated component in the leaf volatiles comes to the terms of monoterpenes. The AVEO exhibits antimicrobial activities against fungal pathogens such as (ITCC 4107) and (MTCC 9913) and bacterial cultures such as (ATCC 13061) and (ATCC 25923). The percent inhibition of AVEO against the and was found up to 50.3% and 33.13%, respectively. The MIC and MBC of the essential oil tested for and were found to be (0.3%, 0.63%) and (0.63%, 2.5%), respectively. Finally, the results revealed that the AVEO characterized by the hydro-distillation and SPME extraction yielded the same chemical profile and showed potent antimicrobial activities. Further research into antibacterial properties can be performed in order to use it as a source for natural antimicrobial medications.
