| the effect of an ethanol extract of catnip (nepeta cataria) on the behavior of the young chick. | the alcohol extract of catnip has a biphasic effect on the behavior of young chicks. low and moderate dose levels (25--1800 mg/kg) cause increasing numbers of chicks to sleep, while high dose levels (i.e. above 2 g/kg) cause a decreasing number of chicks to sleep. | 1979 | 421844 |
| behavioral and toxicological studies of cyclopentanoid monoterpenes from nepeta cataria. | two samples of catnip oil were analyzed by tic, gc, and hplc; the results indicated the presence of 23 components. fractionation of the commercial sample of catnip oil by either distillation or gc yielded 40% nepetalactone and 43% nepetalic acid. catnip oil, nepetalic acid, and a nepetalactone-enriched fraction were evaluated for toxicological and behavioral effects in mice and rats. the ld50 of catnip oil, the nepetalactone-enriched fraction, and nepetalic acid were found in mice to be: 1300 mg ... | 1978 | 672466 |

| cytochrome p-450-catalysed monoterpenoid oxidation in catmint (nepeta racemosa) and avocado (persea americana); evidence for related enzymes with different activities. | a cytochrome p-450 present in ripening avocado (persea americana) fruit mesocarp (cyp71a1) had previously been shown to metabolize the monoterpenoids nerol and geraniol (hallahan et al. (1992) plant physiol. 98, 1290-1297). using dna encoding cyp71a1 as a hybridization probe, we have shown by southern analysis that a related gene is present in the catmint, nepeta racemosa. rna blot analysis, together with western analysis of catmint leaf polypeptides using avocado cyt p-450 antiserum, showed tha ... | 1994 | 7918588 |
| behavioral effects of acute and long-term administration of catnip (nepeta cataria) in mice. | catnip or catmint (nepeta cataria) is a plant used extensively to treat human diseases and in toys for pets. we investigated the effects of acute and long-term administration of the plant on some behaviors of mice. the plant was fed as 10% of the normal diet for 2 h/d for 1 or 7 d. acute and long-term dosing increased both rearing and locomotion frequencies observed in an open field. acute exposure to catnip increased stereotyped behavior and susceptibility to seizures, did not interfere with ha ... | 1995 | 8588288 |
| catnip and the alteration of human consciousness. | uncertainty exists regarding the ability of catnip (nepeta cataria) to affect human consciousness. we report a case of a toddler exhibiting central nervous system depression after consuming a large quantity of catnip. his obtundation was not attributable to another cause. we review the published literature describing the alleged psychoactive capabilities of catnip and present our case as further information for use in this ongoing controversy. | 1997 | 9397511 |

| feeding deterrent effects of catnip oil components compared with two synthetic amides against aedes aegypti. | recently, catnip, nepeta cataria l. (lamiaceae), essential oil has been formulated and marketed as an alternative repellent for protection against biting arthropods by several vendors. we isolated the major active components of catnip oil, e,z- and z,e-nepetalactone, and quantitatively measured their antibiting efficacy compared with the repellents n,n-diethyl-3-methylbenzamide (deet) and chiral (1s,2's)-2-methylpiperidinyl-3-cyclohexene-1-carboxamide (ss220) against the yellowfever mosquito, ae ... | 2005 | 16119554 |
| insecticidal activity of some essential oils against larvae of spodoptera littoralis. | thirty-four essential oils were tested for insecticidal activity (fumigation or topical application) against larvae spodoptera littoralis. twenty essential oils applied by fumigation were highly toxic to the third instar of s. littoralis larvae. two essential oils nepeta cataria and thuja occidentalis were highly toxic, with lc50< or =10.0 ml/m3. five essential oils salvia sclarea, thymus mastichina, origanum majorana, pogostemon cablin and mentha pulegium were toxic with lc50 between 10.1 and 2 ... | 2005 | 16236461 |

| evaluation of a push-pull approach for aedes aegypti (l.) using a novel dispensing system for spatial repellents in the laboratory and in a semi-field environment. | 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 also significantly reduce human-vector contacts and augment existing mosquito control strategies, e.g. t ... | 2015 | 26115365 |
| responsiveness of cats (felidae) to silver vine (actinidia polygama), tatarian honeysuckle (lonicera tatarica), valerian (valeriana officinalis) and catnip (nepeta cataria). | olfactory stimulation is an often overlooked method of environmental enrichment for cats in captivity. the best known example of olfactory enrichment is the use of catnip, a plant that can cause an apparently euphoric reaction in domestic cats and most of the pantherinae. it has long been known that some domestic cats and most tigers do not respond to catnip. although many anecdotes exist of other plants with similar effects, data are lacking about the number of cats that respond to these plants ... | 2017 | 28302120 |
