M. longifolia is one of the most important species of this genus and consists of seven varieties in Iranica Flora. Many researchers studied about identification and correlation between this species and environmental factors. By attention that environmental factors influence the composition of essential oils, so the aim of this study is to analyze the composition of the oil of Mentha longifolia growing wild in different areas of Northern parts of Iran. Based on our results, monoterpenes and sesquiterpenes are the most chemical compounds in this species. The major components were Carvon ( 1.1- 26.6%); 1,8-cineol (3.4- 11.2%); cis-piperitone oxide(1.59- 34.94%), Pulegone (14.96-31.25%); Menthone (2.8-15.05%) and iso- Menthone (0.96- 43.79%0. M. longifolia var. chlorodictya is reported as the best varity of this species can used in traditional medicine and breeding programs. Keywords: Chemical component, Iran, Lamiaceae, Mentha INTRODUCTION Species (commonly known as mint), belonging to the Lamiaceae family, are widely distributed in Eurasia, Australia and South and North of Africa [1,2].

Patrick*, Jessie Bowers*, Shannon Read*, Brett R. Lackey, Christine Murphy, and Sandra L. Gray Clemson University, Clemson, SC 29634 *Undergraduate authors. All contributed equally to this manuscript. Plant essential oils (EO) are used as perfumes, lotions and air fresheners because of their pleasant aromas, but EO also have the ability to elicit changes in mood and behavior. These activities are influenced by the mode of administration and by multiple signaling pathways. The EO aromas from organically grown apple mint (Mentha suaveolens) and passionflower fruit (Passiflora incarnata) were assessed for their effects on cognition and coordination. Participants completed two tasks designed to test working memory and bimanual task efficiency in rooms infused with apple mint, passionflower fruit or control EO. Bimanual coordination was assessed using the Intercept2 program and the Memory Span component of CogLab 2.0 was utilized as a test of working memory. Then, the EO were analyzed by GC-MS, resulting in the identification of several compounds with affinity towards olfactory receptors and neurotransmitter systems. For specific memory subtests within CogLab, EO from apple mint aided number recall, whereas passionflower fruit hindered recall of numbers and letters that sound similar. Passionflower fruit EO slightly enhanced bimanual task coordination. The results indicate that specific aromas may differentially affect task performance.

The oil and leaves are used to make medicine. Throughout history, both American pennyroyal and European pennyroyal have been used interchangeably as a source of oil. Despite serious safety concerns, pennyroyal is used for colds, pneumonia, and other breathing problems. It is also used for stomach pains, gas, intestinal disorders, and liver and gallbladder problems. Women use it to start or regulate their menstrual periods, or to cause an abortion. Pennyroyal is also used to control muscle spasms, cause sweating, and increase urine production. Some people use it as a stimulant and to counteract weakness. Pennyroyal is applied to the skin to kill germs, keep insects away, and treat skin diseases. It is also used topically for gout, venomous bites, and mouth sores; and as a flea-killing bath. In foods, pennyroyal is used for flavoring. In manufacturing, pennyroyal oil is used as a dog and cat flea repellent; and as a fragrance for detergents, perfumes, and soaps. How effective is it? Natural Medicines Comprehensive Database rates effectiveness based on scientific evidence according to the following scale: Effective, Likely Effective, Possibly Effective, Possibly Ineffective, Likely Ineffective, Ineffective, and Insufficient Evidence to Rate. The effectiveness ratings for PENNYROYAL are as follows: Insufficient evidence to rate effectiveness for... Causing abortion.

    Staminal Evolution in the Genus Salvia (Lamiaceae): Molecular Phylogenetic Evidence for Multiple Origins of the Staminal Lever

    Staminal Evolution In The Genus Salvia (Lamiaceae): Molecular Phylogenetic Evidence For Multiple Origins Of The Staminal Lever Jay B. Walker & Kenneth J. Sytsma (Dept. of Botany, University of Wisconsin, Madison) Annals of Botany (in press) Abstract • Background and Aims - The genus Salvia has traditionally included any member of the tribe Mentheae (Lamiaceae) with only two stamens and with each stamen expressing an elongate connective. The recent demonstration of the non-monophyly of the genus presents interesting implications for staminal evolution in the tribe Mentheae. In the context of a molecular phylogeny, we characterize the staminal morphology of the various lineages of Salvia and related genera and present an evolutionary interpretation of staminal variation within the tribe Mentheae. • Methods. Two molecular analyses are presented in order to investigate phylogenetic relationships in the tribe Mentheae and the genus Salvia. The first presents a tribal survey of the Mentheae and the second concentrates on Salvia and related genera. Schematic sketches are presented for the staminal morphology of each major lineage of Salvia and related genera. • Key Results. These analyses suggest an independent origin of the staminal elongate connective on at least three different occasions within the tribe Mentheae, each time with a distinct morphology. Each independent origin of the lever mechanism shows a similar progression of staminal change from slight elongation of the connective tissue separating two fertile thecae to abortion of the posterior thecae and fusion of adjacent posterior thecae. We characterize a monophyletic lineage within the Mentheae consisting of the genera Lepechinia, Melissa, Salvia, Dorystaechas, Meriandra, Zhumeria, Perovskia, and Rosmarinus. • Conclusions.

We suggest a method of constructing red numbers for plant species, in order to set priorities in con- servation policy. The red number is an additive index, summarising values of four parameters: 1. Rarity – The number of sites (1 km2) where the species is present. A rare species is defined when present in 0.5% of the area or less. 2. Declining rate and habitat vulnerability – Evaluate the decreasing rate in the number of sites and/or the destruction probability of the habitat. 3. Attractivity – the flower size and the probability of cutting or exploitation of the plant. 4. Distribution type – scoring endemic species and peripheral populations. The plant species of Israel were scored for the parameters of the red number. Three hundred and seventy (370) species, 16.15% of the Israeli flora entered into the “Red List” received red numbers above 6. “Post Mortem” analysis for the 34 extinct species of Israel revealed an average red number of 8.7, significantly higher than the average of the current red list.

The obtained polymeric films consisted of PLA, a natural biocide, and tea tree essential oil (5–20 wt. %) was prepared with or without an addition of 5 wt. % PEG. The PLA-based materials have been tested, taking into account their morphology, and their thermal, mechanical and antibacterial properties against Staphylococcus aureus and Escherichia coli. It was established that the introduction of a plasticizer into the PLA–TTO systems leads to an increase in tensile strength, resistance to deformation, as well an increased thermal stability, in comparison to films modified using only TTO.
