ABSTRACT Genus Nepeta (family Lamiaceae ) is native to Europe, Asia, and Africa and they are commonly known as catmints. The essential oils of Nepeta genus are characterized by the presence of one or more of the nepetalactone isomers which are the biochemical markers of this genus. The major compounds present in the essential oils of different Nepeta species have been summarized in this review article. KEYWORDS Nepeta, Phytochemical and Aromatic.

These SMs (less toxic and biodegradable) and their derivatives have been recognised as versatile source of biologically active drugs. The most of the drugs used in present medicinal system have direct or indirect relation with secondary metabolites. So, during last few decades the interest has increased in the study of phytochemical composition of aforementioned plants to evaluate their prospective in modern medicinal system. Amongst various plant families which have been known for their medicinal and therapeutic values, Labiatae (Mint) family (Genus Nepeta) remains quite important. Essential oils extracted from various parts of species of above said genus have been a vital source of terpenoid and oxygenated terpenoid hydrocarbons especially sesquiterpene hydrocarbons and their oxygenated derivatives. These compounds have been known for their inherent biological activities viz. sedative, diaphoretic, feberifuge, expectorant, diuretic, stomach tonic, antispasmodic, antipyretics, anti-viral, anti-inflammatory, antimicrobial, fungicidal, insecticidal, insect repellent and antidote against snakes and scorpion bites etc. The present communication constitutes a review on the chemical composition of essential oils (only key constituents) extracted from genus Nepeta along with the details of their specific area of collection, height, specific time in a year, stage of plant collection, method used for extraction and technique of analysis.

  • Trichomes Morphology and Density Analysis in Some Nepeta Species Of
    ARTICLES Mediterranean Botany ISSNe 2603-9109 http://dx.doi.org/10.5209/MBOT.59574 Trichomes morphology and density analysis in some Nepeta species of Iran Seyed Mehdi Talebi1, Majid Ghorbani Nohooji2, Mahboobeh Yarmohammadi1, Narjes Azizi3, Alex Matsyura4 Received: 9 October 2017 / Accepted: 19 February 2018 Abstract. Nepeta are widely distributed worldwide and in different parts of Iran where seventy-nine species were registered. The essential oil of these aromatic plants, which accumulates and secrets by trichomes, has been used in medicinal and industrial products. In addition, these epidermal structures can be used as taxonomic traits. We examined the morphology and density of leaves trichomes of twelve Nepeta species using the light and scanning electron microscopes. Three types of indumentum are found in these species, which composed of two main types of glandular: peltate and capitate, and non- glandular; branched and unbranched trichomes. The number of the observed hairs differed between the studied species and analyses of variant test (ANOVA) showed significant variations among some of them. CA-joined plot proved that trichomes could be used as distinguishing characteristic. Therefore, we suggested that the type of indumentum and the most abundant glandular and non-glandular trichomes have high taxonomic value in species identification within the genus. Keywords: Nepeta species; trichomes; indumentum; glandular trichomes; non-glandular hairs. Análisis de la densidad y morfología de los tricomas en especies iraníes de Nepeta Resumen. El género Nepeta se distribuye ampliamente en todo el mundo y, más concretamente, en distintas partes de Irán donde se registran setenta y nueve especies. El aceite esencial de estas plantas aromáticas se acumula en tricomas y ha sido utilizado en productos industriales y también medicinales.

Pollen morphology and ultrastructure were investigated with light, scanning electron and transmission electron microscopy. Nepetinae pollen is small to large (P=16–65 µm, E=17–53 µm), oblate to prolate (P/E=0.7–1.6) in shape and mostly hexacolpate (sometimes octocolpate). The exine stratification in all taxa studied is similar and characterized by unbranched columellae and a continuous, granular endexine. Sexine ornamentation in the Nepetinae is bireticulate, microreticulate or perforate. In perforate and microreticulate pattern a tendency towards a bireticulum could be recognized due to trace of secondary tectal connections.

  • Catnip and Catmint — What’S the Difference? by Elaine Homstad, Fairfax Master Gardener
    Catnip and Catmint — What’s the Difference? By Elaine Homstad, Fairfax Master Gardener Novice gardeners often disregard botanical names. They just pick up something at the nursery, home improvement store or big-box discount store that bears the common name of a plant they think they want. Such is the case with catnip. True catnip is a perennial herb whose botanical name is Nepeta cataria. Characteristics of Nepeta cataria N. cataria has square, hairy stalks (like all members of the mint family) and gray-green heart-shaped leaves with scalloped edges. It has rather small and unremarkable white flower spikes, often appearing only late in the season. N. cataria grows to about 30 inches high, has a spreading habit, and can be rather weedy looking, with a tendency to crowd out other plants around it. But this is the variety that appeals to most cats, so if you are growing it for your feline friends, be certain you get this variety. photo: Richard Hawke, Chicago Characteristics of Nepeta Catmint Nepata faassenii Walker’s Low The genus Nepeta is a member of the mint family (Lamiaceae), of which there are approximately 250 species. Many Nepetas besides N. cataria are called catnip, but they really should bear the common name of catmint. These are the varieties that are most commonly sold, and they actually perform better in the garden as a flowering perennial than does “true” catnip. Most have longer and larger flower spikes in shades of purple, blue, pink or white. The flowers appear in late spring to early summer, last for many weeks and frequently rebloom throughout the growing season.
