Background & Aim:Nepeta racemosa is an herbal and medicinal plant and this report aims to   identify chemical compositions of the essential oils and volatiles of its   aerial parts through classical and advanced methods.  Experimental: Chemical profiles of the essential oils and volatile compounds from the aerial parts of Nepeta racemosa obtai...

The chemical composition of Matricaria chamomilla L. and Nepeta cataria L. essential oils was determined by GC-MS on an apolar stationary phase by comparison of the characteristic fragmentation patterns with those of the Wiley 275L database. The GC-MS chromatograms were compared with those obtained by fast GC equipped with a direct resistively heated column (Ultra Fast Module 5% phenyl, 5 mx 0....

A ESSENTIAL oil, nepetalactone. was isolated from the catnip plant (Nepeta cataria) by McElvain et al.-' 3i 4 and Meinwald. McElvain demonstrated with lions that the oil is the substance which is responsible for the attraction of cats to the plant and the only constituent capable of inducing a response. This familiar response has been broken down into four components, viz, 1) sniffing, 2) licki...

The increase in insecticide resistant mosquito populations necessitates the exploration of novel vector control intervention measures. Push-pull strategies for insect control have been successful when used in integrated crop pest management. Through the combinatory use of deterring and attracting stimuli, the abundance of insect pests can be changed in a given area. A push-pull strategy might a...

This study was designed to evaluate, for the first time, antioxidant and antimicrobial activities of Nepeta × faassenii essential oil (NEO). Twenty-six compounds were identified by gas chromatography mass spectrometry analysis, which 4a alpha,7alpha,7a alpha-nepetalactone (34.12%), elemol (23.23%), spiro(5,6)dodecane (13.73%), 3,4 alpha-dihydro-4a alpha, 7 7a (7.93%) major compounds. The NEO ex...

The tea aphid ( Toxoptera aurantii Boyer de Fonscolombe) is an important plant pest insect worldwide. parasitoid wasp, Aphelinus sp., one of the most natural enemies in China. Unfortunately, sp. alone cannot effectively control outbreaks under conditions. In this study, 27 volatile compounds from aphid-injured shoots, flowers, sex pheromones, or body rinses were selected and tested Y-tube olfac...

Nepeta cataria L. has been used in traditional medicine of some countries. Here the cytotoxic and apoptogenic activity of methanol extracts, n-hexane, dichloromethane, ethyl acetate, n-butanol, and acqueous extracts and the essential oil obtained from the aerial parts of the plant were evaluated with PC3, DU-145 and MCF-7 cell lines. Cell viability, histograms of PI stained fragmented DNA in ap...

Green lacewings (Neuroptera: Chrysopidae) are voracious predators of aphids and other small, soft-bodied insects and mites. Earlier, we identified (1R,2S,5R,8R)-iridodial from wild males of the goldeneyed lacewing, Chrysopa oculata Say, which is released from thousands of microscopic dermal glands on the abdominal sterna. Iridodial-baited traps attract C. oculata and other Chrysopa spp. males i...

Objective: The genus Psammogeton, belonging to the Umbelliferae family, has 4 annual species in Iran. In the present work, Psammogeton canescens (DC) Methods: Vatke was collected from Saheb-al-Zaman Mountain slope, northeast of Kerman province, Iran in May 2013. The essential oils of leaves, flowers and stems of the plantwere separately extracted using hydrodistillation method...
