The amplified fragment length polymorphism (AFLP) method was used to evaluate genetic diversity and to assess genetic relationships within the section Mentha in order to clarify the taxonomy of several interspecific mint hybrids with molecular markers. To this end, genetic diversity of 62 Mentha accessions from different geographic origins, representing five species and three hybrids, was asses...

Les phytophotodermatoses sont des éruptions cutanées engendrées par le contact avec une substance végétale et exagérées lors de l'exposition au rayonnement solaire. Elles sont dues à la présence de furocoumarines (psoralènes, xanthotines, bergaptènes) dans la plante et font intervenir deux mécanismes de photosensibilisation cutanée : photo-toxicité ou photo-allergie. Nous rapportons une observa...

Mentha piperita (MP), also known as peppermint, is an aromatic and medicinal plant widely used in the food industry, perfumery and cosmetic, pharmacy and traditional medicine. Its essential oil (EO) displays antimicrobial activity against a range of bacteria and fungi. In this study, we found that MP EO lethal cytotoxicity is associated with increased levels of intracellular reactive oxygen spe...

DNA fingerprints led to the identification of closely related plant species and it is one of the tool for assessing genetic diversity and species relationship. DNA is most stable and does not vary seasonally and with age of the plant. DNA based fingerprinting techniques plays greater role in authentication of botanicals. This review gives an outline about the importance of DNA fingerprinting, D...

Efficacy of 25 essential oils was screened against filarial vector, Culex quinquefasciatus, for their larvicidal and knockdown effects in a preliminary study. Of these, 8 oils viz. calamus oil, cinnamon oil, citronella oil, clove oil, eucalyptus oil, lemon oil, mentha oil and orange oil exhibited 100% larvicidal activity at 1000 ppm and 100% knockdown effect at 10% concentration. These 8 oils w...

p-Mentha-1,8-dien-7-al is a naturally occurring cyclic alpha,beta-unsaturated aldehyde that is used as a flavoring substance throughout the world. Due to the chemical structure and the potential DNA reactivity of the alpha,beta-unsaturated carbonyl moiety, a battery of genotoxicity assays was requested by the European Food Safety Authority. Previous genotoxicity studies on the substance gave mi...

The aim of this study was to optimize the extraction of p-menthadienol isomers and aristolone from the essential oil of Elyonurus hensii by hydrodistillation. The study of the seasonal variation in the chemical composition has shown that the plant material has been subject to a natural selection regarding the biosynthesis of the p-menthadienol isomers: during periods of water stress, the extrac...

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....
