Functional gastrointestinal disorders are among the most common diseases. The treatment of these conditions must be comprehensive. The foundation of therapy includes lifestyle modifications, appropriate dietary adjustments, physiotherapy, and pharmacotherapy. Herbal medicines can also play a significant role in self-treatment.

The western flower thrips (Frankliniella occidentalis Perg.) is one of the most economically important insect pests of greenhouse plants. Plant protection against this pest is based predominantly on synthetic insecticides; however, this form of protection poses problems in terms of thrip resistance to the active substances, along with health risks associated with insecticide residues on the treated plants. Therefore, new active substances need to be sought. Essential oils could be a new, appropriate, and safe alternative for greenhouse culture protection. As greenhouses are enclosed areas, fumigation application of EOs is possible. This paper presents acute toxicity results for 15 commercial EOs applied by fumigation, as well as the effect of sublethal concentrations on fertility of F. occidentalis females. The most efficient EOs were obtained from Mentha pulegium and Thymus mastichina, with LC50(90) estimated as 3.1(3.8) and 3.6 (4.6) mg L-1 air, respectively. As found for the very first time, sublethal concentrations of EOs could result in a significant reduction in the fertility of surviving T. occidentalis females. Among the tested EOs, the EO from Nepeta cataria provided the highest inhibition of fertility, with EC50(90) estimated as 0.18 (0.36) mg L-1 air. Chemical composition of the most efficient EOs and possible applications of the results in practice are discussed. In conclusion, in light of the newly determined facts, EOs can be recommended as active substances for botanical insecticides to be applied against Thysanopteran pests by fumigation.

Rastliny čeľade Lamiaceae obsahujú účinné látky prevažne v listoch. V podčeľadi Nepetoideae, kam patrí rod Mentha L., ide hlavne o silicu a fenolové látky s antioxidačnou aktivitou, najmä hydroxyškoricové kyseliny s prevahou kyseliny rozmarínovej a flavonoidy. Medicínsky a priemyselne využívané sú najmä mäty M. × piperita a M. spicata, druh M. x villosa je u nás menej známy. Listové drogy sa spravidla hodnotia ako celok, ojedinele sa hodnotia jednotlivé listové inzercie. V tejto práci sa sledoval liekopisnými metódami v jednotlivých listových pároch Mentha × villosa Huds. cv. Snežná celkový obsah hydroxyškoricových derivátov (THD) vyjadrených ako kyselina rozmarínová a flavonoidov luteolínového typu, ktoré sa v tejto rastline vyskytujú v najväčšom množstve. Obsah THD vo vodných extraktoch listových párov kolísal v rozmedzí 6,7–9,4 %, v metanolových extraktoch 6,6–14,0 %. Flavonoidy stanovené ako luteolín-7-O-glukozid sa nachádzali vo vodných extraktoch v množstve 4,0–8,8 %, v metanolových extraktoch v množstve 4,0–10,5 %. Antioxidačná aktivita (DPPH) stanovená ako SC50 kolísala vo vodných extraktoch listových párov v rozmedzí 10,2–16,9 μg.ml–1 (suchej hmotnosti drogy), v metanolových extraktoch v rozmedzí 10,7 až 21,6 μg.ml–1. Najvyšší obsah fenolových látok a najvyššia antioxidačná aktivita bola v extraktoch z vrcholových listov, najnižší obsah fenolových látok a najnižšia antioxidačná aktivita sa zaznamenala v extraktoch listov zo strednej časti stonky.
Lamiaceae plants mostly accumulate active ingredients in their leaves. The subfamily Nepetoideae, including the genus Mentha L., is characterized by the presence of essential oil and antioxidant phenolics, chiefly hydroxycinnamic acids with predominance of rosmarinic acid, and flavonoids. Mentha × piperita and M. spicata are the most broadly used mints in both medicine and industry, while M. x villosa is less known in our country. Herbal drugs in the form of leaves are usually analysed unpartitioned, while single leaves insertions have only been studied occasionally. Therefore, the aim of this work was the quantification of the active compounds content in the leaves pairs of Mentha × villosa Huds. cv. Snežná, using pharmacopoeial methods: total hydroxycinnamic derivatives expressed as rosmarinic acid (THD) and luteolin-type flavonoids. THD content ranged from 6.7% to 9.4% in the leaves pairs’ water extracts, and from 6.6% to 14.0% in methanol extracts. Flavonoids contents, expressed as luteolin-7-O-glucoside, ranged from 4.0% to 8.8% in water extracts, and from 4.0% to 10.5% in methanol extracts. Antioxidant activity (DPPH) expressed as SC50 ranged from 10.2 to 16.9 μg.ml–1 (drug dry weight) in water extracts, and from 10.7 to 21.6 μg.ml–1 in methanol extracts. The highest content of phenolic compounds as well as the highest antioxidant activity were found to be in the top sheet, while the lowest content of phenolic compounds and lowest antioxidant activity were detected in the leaves of the middle stem part.

In this work aqueous infusions from ten Mentha herbal samples (four different Mentha species and six hybrids of Mentha x piperita) and 20 different peppermint teas were screened by capillary electrophoresis with UV detection. The fingerprint separation was accomplished in a 25 mM borate background electrolyte with 10% methanol at pH 9.3. The total polyphenolic content in the extracts was determined spectrophotometrically at 765 nm by a Folin-Ciocalteu phenol assay. Total antioxidant activity was determined by scavenging of 2,2-diphenyl-1-picrylhydrazyl radical at 515 nm. The peak areas of 12 dominant peaks from CE analysis, present in all samples, and the value of total polyphenolic content and total antioxidant activity obtained by spectrophotometry was combined into a single data matrix and principal component analysis was applied. The obtained principal component analysis model resulted in distinct clusters of Mentha and peppermint tea samples distinguishing the samples according to their potential protective antioxidant effect. Principal component analysis, using a non-targeted approach with no need for compound identification, was found as a new promising tool for the screening of herbal tea products.

The genus Mentha of the family Lamiaceae has great importance due to the essential oils content and their commercial utilization. The antioxidant activities of essential oil of five Mentha species were estimated spectrophotometrically using 2,2-diphenyl-1-picrylhydrazyl free radical (DPPH). The analysis of essential oils was performed by GC-MS. The most active was essential oil of M. spicata rich in carvacrol and thymol. Lowest activity was detected in M. longifolia var. lavanduliodora, rich in β-linalool.
