Essential Oils of<i>Mentha</i>Species from Northern Turkey

“…Members of this genus are the only sources for the production of one of the most economically important essential oil menthol throughout the world. Some members are also used as herbal teas and condiments in both fresh and dried form due to their distinct aroma (Baser and Kurkcuoglu 1999). Besides these, various bioactivity of the genus Mentha has also been reported.…”

Plant cell culture provides an alternative means for producing secondary metabolites. In this study, experiments were carried out to study the impact of several parameters, independently and in combination, on the stimulation of menthol production in the cell suspension culture of Mentha piperita. Callus was obtained from leaf segments of in vitro grown plantlets on Murashige and Skoog (MS) medium supplemented with 0.2 mg l −1 of 2,4-dichlorophenoxy acetic acid to initiate cell suspension culture. This culture was maintained in half-strength MS medium supplemented with 0.2 mg l −1 of 2,4-dichlorophenoxy acetic acid at 15 d interval and used for further studies. Precursor feeding alone, i.e., menthone, at 35 μM concentration showed slightly improved productivity. γ-Cyclodextrin alone at 60 μM concentration and in combination with menthone feeding at 35 μM increased menthol yield up to 92 and 110 mg l −1 in comparison to 77 mg l −1 of control culture. Synergistic potentiation effect of menthone feeding at 35 μM and γ-cyclodextrin at 60 μM treatment followed by in situ adsorption with RP-8 also showed potential stimulation of menthol production in M. piperita cell culture. Fungal elicitor treatment showed enhanced production level up to 140.8 mg l −1 in comparison to that of control. Further studies were carried out with the establishment of Agrobacterium tumefaciens (Ach5) gall-mediated calli, and consequently, cell suspension culture and results showed the significant enhancement of menthol yield up to 278 mg l −1 .

“…Previous studies have shown that oil of M. pulegium varies within and among geographic-climatic zones [12,13]. Pulegone (17.5-70.2%) constitutes the major compound of this oil [12,14].…”

Aerial parts of Mentha pulegium L. collected from south east of Algeria (Reguiba, El-Oued) possessed an essential oil in 2.34% (v/w) yield. GC and GC-MS analysis of the oil revealed recognition of Thirty-seven compounds, representing 95.02% (area percent) of the total oil composition. Oil was rich in Oxygenated hydrocarbons, exhibited higher percentage of Pulegone (46.31%) followed by Piperitenone (23.3%), Menthone (6.2%) and Limonene (4.7%). The antioxidant activity by DPPH free radical scavenging bioassay (IC 50 = 157 µl/ml).
