Repellent activity of catmint, Nepeta cataria, and iridoid nepetalactone isomers against Afro-tropical mosquitoes, ixodid ticks and red poultry mites.
The repellent activity of the essential oil of the catmint plant, Nepeta cataria (Lamiaceae), and the main iridoid compounds (4aS,7S,7aR) and (4aS,7S,7aS)-nepetalactone, was assessed against (i) major Afro-tropical pathogen vector mosquitoes, i.e. the malaria mosquito, Anopheles gambiae s.s. and the Southern house mosquito, Culex quinquefasciatus, using a World Health Organisation (WHO)-approve...
متن کاملIdentification of iridoid synthases from Nepeta species: Iridoid cyclization does not determine nepetalactone stereochemistry
Nepetalactones are iridoid monoterpenes with a broad range of biological activities produced by plants in the Nepeta genus. However, none of the genes for nepetalactone biosynthesis have been discovered. Here we report the transcriptomes of two Nepeta species, each with distinctive profiles of nepetalactone stereoisomers. As a starting point for investigation of nepetalactone biosynthesis in Ne...
متن کاملPharmacognosy of Nepeta Cataria
Nepeta cataria Linn (Family Labiatae), commonly known as catnip, is a herbaceous plant and is a native of southeast Europe, Orient, Southwest Asia and Western temperate Himalayas. Leaves and flowering tops, which contain tannin and volatile oil are aromatic, carminative, tonic, diaphoretic, refrigerant, emmenagogue, antiseptic, stimulant and useful in infantile colic and hysteria. Leaves are de...
متن کاملBehavioral activity of catnip (Lamiaceae) essential oil components to the German cockroach (Blattodea: Blattellidae).
The essential oil of catnip, Nepeta cataria L., contains two isomers of nepetalactone, E,Z-and Z,E-nepetalactone, and was tested for repellent activity to adult male German cockroaches, Blattella germanica (L.), in a choice-test arena. The two isomers of nepetalactone were purified by using preparative thin-layer chromatography and tested for behavioral activity in the choice-test arena. Signif...
متن کاملCyclopentanoid terpene biosynthesis in a phasmid insect and in catmint.
The stick insect, Anisomorpha buprestoides, and the catmint, Nepeta cataria, produce closely related cyclopentanoid terpenes, anisomorphal and nepetalactone. Tracer experiments with isotopes indicate that anisomorphal is synthesized by the walking stick from normal terpene precursors (acetate or mevalonate). In the catmint plant, isolated leaf disks synthesized nepetalactone, utilizing the same...
