Comparative biological and antiquorum activity of extracts of lamiaceae plants, grown in the Russian Federation

The purpose of this study was to assess the biological activity and antiquorum activity of extracts of Lamiaceae plants. Material and methods. Extracts of 4 medicinal plants of the Lamiáceae were used as test substances. Bioluminescent analysis were used on the model Escherichia coli MG1655 and antiquorum activity of medicinal plant extracts - on the model Chromobacterium violaceum ATCC 31532. Result. An analysis of the bioluminescent testing of Mentha piperita leaf aqueous extract showed no toxic effect throughout the entire record period over the entire concentration range. Low concentrations of analyte (0.625 mg/ml - 0.0097 mg/ml) cause a slight induction of lux-operon. Sālvia officinālis extract showed a slight antibacterial effect on the tested strain (EC50 = 10 mg/ml). The effect is achieved after 50-60 minutes of contact of microbial cells with components of Sālvia officinālis extract and persists until the end of the analyzed period of time (180 minutes). Extract of Oríganum vulgáre showed a decrease in the level of luminescence by 30% when the analyte was exposed to a concentration of 10 mg/ml. The extract of Thýmus serpýllum showed a pronounced antibacterial effect on the test organism, with a maximum concentration of 10 mg/ml, a 50% inhibition of luminescence is observed. All the tested compounds in subinhibitory concentrations suppressed the quorum-dependent biosynthesis of violacein.

One of the most important compounds that exhibit a wide range of biological activities with especially strong antioxidant action are plant polyphenols. In the course of the experiment, the dose-dependent effects of polyphenols-rich extracts isolated from the Lamiaceae family Kazakhstani plants were studied on the processes of lipid peroxidation and on the degree of erythrocytes hemolysis. The activity of aqueous-ethanolic extracts from dried parts of plants, such as Origanum vulgare, Ziziphora bungeana, Dracocephalum integrifolium, Mentha piperita, Leonurus turkestanicus, Thymus serpyllum, and Salvia officinalis, was studied in a Wistar rat model. Lipid peroxidation (LPO) in liver microsomes was assessed by measuring malondialdehyde content in the form of thiobarbituric acid-reacting substances (TBARS). Estimation of osmotic resistance of isolated erythrocytes was evaluated based on hemoglobin absorbance. The amount of total phenolics in the extracts was measured using the Folin-Ciocalteu reagent method. Based on the results, Thymus serpyllum extract exhibited a significantly higher antioxidant activity (IC50 = 3.3 ± 0.7) compared to other plant extracts. Accordingly, among the extracts studied, those from Salvia officinalis, Thymus serpyllum, and Origanum vulgare show the most pronounced membrane-stabilizing activity. Antioxidant and antihemolytic properties of green tea and Origanum vulgare extract mixtures were similar to that of each individual plant extract. Similar results were obtained when the green tea extract was mixed with Mentha piperita, Ziziphora bungeana, and Dracocephalum integrifolium extracts, indicating no discernible synergistic interaction.

The antibacterial effect of low concentrations of monocaprylin on Escherichia coli O157:H7 in apple juice was investigated. Apple juice alone (control) or containing 2.5 mM (0.055%) or 5 mM monocaprylin was inoculated with a five-strain mixture of E. coli O157:H7 at ~6.0 log CFU/ml. The juice samples were stored at 23 or 4°C for 14 or 21 days, respectively, and the population of E. coli O157:H7 was determined on tryptic soy agar plates supplemented with 0.6% yeast extract. At both storage temperatures, the population of E. coli O157:H7 in monocaprylin-supplemented juice samples was significantly lower (P < 0.05) than that in the control samples. The concentration of monocaprylin and the storage temperature had a significant effect on the inactivation of E. coli O157:H7 in apple juice. Monocaprylin at 5 mM was significantly more effective than 2.5 mM monocaprylin for killing E. coli O157:H7 in apple juice. Inactivation of E. coli O157:H7 by monocaprylin was more pronounced in juice stored at 23°C than in the refrigerated samples. Results of this study indicated that monocaprylin is effective for killing E. coli O157:H7 in apple juice, but detailed sensory studies are needed to determine the organoleptic properties of apple juice containing monocaprylin.

Long days (16 h light), high photon flux density (1200 �Em-2 s-1.) and high night temperature (20°C) resulted in the highest oil yield. : Daylength, night temperature, day temperature and photon flux density were important interacting factors determining oil composition. The photosynthate model proposed by Burbott and Loomis (Plant Physiol., 1967, <B.42, 20-8) explained the effect of environmental factors with respect to pulegone, menthone and menthofuran. Factors favouring the maintenance of high levels of photosynthate resulted in high concentrations of menthone and low concentrations of pulegone and menthofuran. The photosynthate model does not explain the effect of environmental factors on several other monoterpenes.

The ametryne herbicide is largely used on sugar cane plantation in Brazil. It is persistent in the environment and can be found in bodies of water, impacting the aquatic and terrestrial ecosystems. Generally, in crops are applied mixtures of herbicides in order to obtain a higher success in combating weeds. This study evaluated the toxicity only of ametryne herbicide, without mixture with other herbicides, in order to quantify only the degree of dangerousness. This work evaluated the toxicity of ametryne to one aquatic test organism (Daphnia similis) and two land test organism (Eruca sativa and Lactuca sativa). Immobility of D. similis was evaluated in the presence of ametryne. Influences of ametryne on seed germination and root growth of E. sativa and L. sativa were evaluated. Even at low concentrations (5.00 mg/L), ametryne caused toxic effects on the mobility of D. similis, and 0.25 g/L caused toxic effects on the seeds. Root growth and the percentage of inhibition showed greater sensitivity to ametryne compared with seed germination. Thus, ametryne resulted in toxic effects to the analyzed organisms, which may bring damage to both aquatic and terrestrial ecosystems.

Lipid photooxidation is the undesirable chemical process in which singlet oxygen result in the peroxidation of fatty acids. In this study leaves methanolic extracts of peppermint (Mentha piperita L.), marjoram (Origanum majorana L.), rosemary (Rosmarinus officinalis L.) and sage (Salvia officinalis L.) were applied as the natural singlet oxygen scavenger. Amount of flavonoid compounds as the singlet oxygen scavenger agent in these plant species were decreased in the order of peppermint > marjoram> sage > rosemary. Also, The rate of quenching of singlet oxygen in the presence of 1,4-Diazabicyclo[2.2.2]octane (DABCO) as a well-known singlet oxygen scavenger and highly effective synthetic antioxidants in food industry such as Butylated hydroxyanisole (BHA), tert-Butylhydroquinone (TBHQ) and peppermint decreased in the order of peppermint > BHA > TBHQ > DABCO >. Furthermore, photooxidation of oleic acid as an unsaturated fatty acid in the presence of DABCO, peppermint, BHA and TBHQ indicated a preservation of 82.77%, 73.39%, 71.57% and 53.10% on peroxidation of oleic acid, respectively which reveals peppermint has an efficient role on protection of fatty acids from photooxidation. Practical application: In this study, it was confirmed that peppermint (Mentha piperita L.) performs an effective role in restricting or limitation of singlet oxygen generation and fatty acid photooxidation. In vitro study of scavenging effect of peppermint can correlate laboratory results to commercial scale up. However, this would also necessitate the progress of improved methods for the measurement of lipid peroxidation in vivo in the presence of peppermint.
