The equation of state Soave-Redlich-Kwong (SRK) and its modification (predictive SRK or PSRK) are applied to simulate multicomponet distillation, which separate main component of spearmint essential oil. The simulation model is based on bubble point method, and the Wang-Henke algorithm. Spearmint essential oil is considered in the study and the original experimental data were obtained f...

In the present study effort have been made to find the anti-bacteria effect of six medicinal plant essential oil namely, Ocimum bascilicum (Basil oil), mentha arvensis (Cormint oil),Zingiber officinale(ginger oil),citrus limon(lemon oil), thymus mastichina (Marjoram oil) and mentha spicata (Spearmint oil) were assessed for anti bacterial activity against therefore pathogenic bacteria such as B....

Spearmint has one major monoterpene, (-)-carvone, that constitutes up to 90% of all the monoterpenes present. Likewise, the major phenylpropanoid-rosmarinic acid-in spearmint accounts for up to 70% of the phenylpropanoids produced from the plant. These two compounds are each produced by separate distinct biosynthetic pathways which provide an excellent opportunity to study the influence of a wi...

objective: in this study we investigated the effects of spearmint (mentha spicata labiatae) on the reproductive system, fertility and number of offspring in adult male rats. materials and methods: adult wistar male rats in one control (c) and three experimental groups (i, ii and iii) received 0, 10, 20 and 40 mg/kg spearmint extract orally for 45 days, respectively.  following this treatment, t...

The Powder River Basin in Wyoming and Montana contains the United States' largest coal reserve. The area produces large amounts of natural gas through extraction from water-saturated coalbeds. Determining the impacts of coalbed natural gas-produced efflux water on crops is important when considering its potential use as supplemental irrigation water. We hypothesized that coalbed natural gas wat...

Medicinal and aromatic plant species are important sources of secondary metabolites with therapeutic, cosmetic, and food processing applications. The quality of the metabolites, however, frequently varies due to inconsistencies in secondary metabolite composition of plant extracts, especially within the family Lamiaceae. A major contributing factor to these metabolite inconsistencies is undoubt...

objective: evaluation activity was conducted using three spearmint genotypes (wg-spm-engl, spm-fran and spm-eas) and one standard check (wgsm-03) at wondo genet, awassa, debre zeit and allagae during 2012 and 2013 for two years. methods: the treatments were arranged in randomized complete block design with four replications. data on leaf to stem ratio, leaf yield/ha, essential oil content and e...

In a study published previously in this journal (Wilkinson et al., 2002), the effect of chewing gum on cognitive functioning was examined. The results of this study indicated that chewing a piece of gum results in an improvement of working memory and of both immediate and delayed recall of words but not of attention. In the present study, memory and a variety of attentional functions of healthy...

Domestic production of culinary herbs continues to increase in the United States. Culinary are primarily propagated by seed; however, some have poor germination rates and slow growth. Thus, there advantages propagating vegetative stem-tip cuttings as they lead true-to-type plants a shortened time. Previous research ornamental young finished shown reduction rooting time increases plant quality w...
