essential oils are volatile mixtures of hydrocarbons with diverse functional groups. in the current study the effect of essential oils from five medicinal plants including zataria multiflora and nepeta cataria (lamiaceae), tagetes minuta and artemisia sieberi (asteraceae), and trachyspermum ammi (apiaceae) were analyzed using gc-mass spectrometry. the toxicity of these plant essential oils agai...

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....

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...

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...

Both in vitro and in vivo studies were performed in the present research to investigate the pharmacological effects of successive Nepeta cataria extracts on some biochemical parameters in Streptozotocin diabetic rats compared to the currently used drug, Glicalized. These involved some biochemical parameters such as glucose, insulin, carbohydrate hydrolyzing enzymes; α –amylase, αglucosidase, βg...
