Retention Indices for Frequently Reported Compounds of Plant Essential Oils
Retention Indices for Frequently Reported Compounds of Plant Essential Oils V. I. Babushok,a) P. J. Linstrom, and I. G. Zenkevichb) National Institute of Standards and Technology, Gaithersburg, Maryland 20899, USA (Received 1 August 2011; accepted 27 September 2011; published online 29 November 2011) Gas chromatographic retention indices were evaluated for 505 frequently reported plant essential oil components using a large retention index database. Retention data are presented for three types of commonly used stationary phases: dimethyl silicone (nonpolar), dimethyl sili- cone with 5% phenyl groups (slightly polar), and polyethylene glycol (polar) stationary phases. The evaluations are based on the treatment of multiple measurements with the number of data records ranging from about 5 to 800 per compound. Data analysis was limited to temperature programmed conditions. The data reported include the average and median values of retention index with standard deviations and confidence intervals.

SYNTHESIS OF FUSED AND NONFUSED HETEROCYCLES FROM 5- AND 8-SUBSTITUTED 3-HYDRAZINO-l,2,4-TRIAZINO[5,6-Z>]INDOLE Hamida Abdel Hamid, Ahmed Mousaad, El Sayed Ramadan and El Sayed H. El Ashry* Chemistry Department, Faculty of Science, Alexandria University, Alexandria, Egypt Abstract: The 7-and 10-substituted 1,2,4-triazolo[4\3':2,3][l,2,4]triazino[5,6-i]indoles were prepared by the reaction of 5- and 8-substituted-3-hydrazino-l,2,4-triazino[5,6-i>]indole with formic acid ortriethyl orthoformate. Reaction of the hydrazines with acetylacetone, ethyl acetoacetate and ethyl cyanoacetate gave the respective biheterocycles containing pvrazole and pyrazolone rings. Reaction of the hydrazines with carbondisulphide, thiourea, urea, ethyl chloroformate as well as nitrous acid have been investigated. Reaction of 5-allyl-3-methylthio-1,2,4-triazino[5,6-6]indole with ethanolamine followed by cyclization gave the imidazotriazinoindole. INTRODUCTION The l,2,4-triazino[5,6-i]indole ring has been found to be a useful carrier for various functional groups for developing antiviral and antibacterial activities [1-8], The imidazo, pyrimido or triazolo-1,2,4- triazino[5,6-6]indoles showed also antiviral and antibacterial properties [9], The arylidene moiety of 3- arylidene and heterocyclic formylidenehydrazono-l,2,4-triazino[5,6-&]indole derivatives has been found to play a role on their activity against Staphylococcus aureus and Bacillus cereus as well as Ρ 388 lymphocytic leukemia [8]. The 3-hydrazino-1,2,4-triazino[5,6-A]indole and 3-hydrazino-5,6-diphenyl-l,2,4-triazine have an effect on the carbohydrate metabolism and lipid components in rat [10,11], The regioselective annelation of a triazole ring to the 1,2,4-triazino[5,6-b] indole either via the dehydrative cyclization of the respective hydrazide or the dehydrogenative cyclization of the hydrazones has been reported [12-16]. -
