Abstract

Mentha essential oil is one of the most utilized essential oil in the food and pharmaceutical industries. The present study reports the chemical composition and antibacterial properties of leaf essential oils of Mentha species. Further, the effect of the harvesting period on essential oil yield was also investigated. Firstly, the cultivated Mentha piperita and wild Mentha longifolia, revealed significant differences in their chemical profile. M. longifolia essential oil was characterized with endo-borneol (1.12-6.2%), caryophyllene (2.72-7.03%), isopipertenone (0.07-0.36%), germacrene D (0.98-3.22%), 3-cyclopentene-1-one,2-hydroxy-3-(3-methyl-2-butenyl)- (21.91-56.72%) and piperitone oxide (8.96-39.31%), whereas, M. piperita leaves essential oil was found rich in isomenthone (5.97-6.75%), 1-menthone (7.32-18.32%) and menthol (18.03-58.53%), etc. The essential oils of both Mentha species exhibited strong antimicrobial activity as evaluated using poisoned food technique, dry weight method, and disc diffusion method against Candida albicans, Fusarium oxysporum, Bacillus subtilis, Staphylococcus aureus, Klebsiella pneumoniae and Escherichia coli. Secondly, the maximum essential oil yield was observed in July month, 0.63±0.01 and 0.56±0.01%, respectively for M. piperita and M. longifolia.

Highlights

  • Mentha is one of the most important genera of the Lamiaceae family, and its medicinal and aromatherapeutic effects have been known since ancient times.[1]

  • The results showed that the least essential oil yield was achieved in April (0.26±0.02% and 0.63±0.01%, respectively) and the maximum was achieved in July month

  • Values revealed the maximum fungicidal activity against C. albicans in July month (MIC-1.5 mg/ mL), whereas, essential oil of May month harvest showed maximum antifungal activity (MIC-1.5 mg/ mL) against F. oxysporum (Table 7). These findings proved that both Mentha species essential oil were more efficient against Candida albicans than F. oxysporum

Summary

Introduction

Mentha is one of the most important genera of the Lamiaceae family, and its medicinal and aromatherapeutic effects have been known since ancient times.[1]. M. longifolia, often known as wild mint, is a plant native to Africa, Europe, and Asia that has long been traditionally used to cure bronchitis, nausea, anorexia, flatulence, ulcerative colitis, and liver problems.[3,4] The antioxidant, anti-inflammatory, antimicrobial, analgesic, stimulant, carminative, diaphoretic, antiemetic, antispasmodic, anticatarrhal, emmenagogue, and anticarcinogenic properties have been documented for the species.[2,3] M. piperita L., commonly known as peppermint, is a popular tonic herb and flavoring ingredient It is a sterile hybrid from a cross between spearmint (M. spicata) and water mint (M. aquatica).[5] In the past, headache, migraine, vomiting, bronchitis, menstrual cramps, and digestive diseases like irritable bowel syndrome and constipation have all been treated with this species.[6] this species exhibit astringent, antiseptic, antipyretic, analgesic, anticarcinogenic, antioxidant, and antispasmodic property.[7]
