High impact information on Nepeta

• Using a PCR-based approach, two novel cytochrome P450 cDNAs were isolated from a catmint (Nepeta racemosa) leaf cDNA library [1].
• The acetone extract of Nepeta caesarea yielded four new nepetalic acid derivatives, 3'alpha-[beta-sitosteryl-3beta-oxy]dihydronepetalactone (1), 3'beta-[5alpha-stigmast-7-ene-3beta-oxy]dihydronepetalact one (2), 3'alpha-[olean-12-ene-28-oyl-3beta-oxy]dihydronepetalactone (3), and 3'alpha-[lup-20(29)-ene-28-ol-3beta-oxy]dihydronepetalactone (4) [2].
• Nepetalactone: a new opioid analgesic from Nepeta caesarea Boiss [3].
• Coleon U 12-methyl ether from Nepeta leucophylla [4].
• We assayed the radical scavenging activity of Nepeta sibthorpii methanol extract by the 1,1-diphenyl-2-picrylhydrazyl (DPPH) method [5].

Associations of Nepeta with chemical compounds

• Isolation and GC/MS quantitative determination of ursolic acid in the herb of Nepeta cataria var. citriodora have been performed [6].
• New isopimarane diterpene and new cineole type glucoside from Nepeta prattii [7].
• Together with sixteen known compounds, a new isopimarane diterpene (prattol) and a new cineole type glucoside were isolated from Nepeta prattii [7].
• Behavioral and toxicological studies of cyclopentanoid monoterpenes from Nepeta cataria [8].
• Antimicrobial activity of the essential oil of Calamintha nepeta and its constituent pulegone against bacteria and fungi [9].

Gene context of Nepeta

• We show that cyt P450 from the plants Catharanthus roseus and Nepeta racemosa are capable of hydroxylating geraniol, nerol and citronellol, and thus do not impose precursor specificity on iridoid biosynthesis in plants [10].

Analytical, diagnostic and therapeutic context of Nepeta

• Determination of nepetalactone in Nepeta cataria by reversed phase high performance liquid chromatography [11].
