Chemical communication is fundamental to success in social insect colonies. Species-, colony-, and caste-specific blends of cuticular hydrocarbons (CHCs) and other chemicals have been well documented as pheromones, mediating important behavioral and physiological aspects of social insects. More specifically, royal pheromones used by queens (and kings in termites) enable workers to recognize and care for these vital individuals and maintain the reproductive division of labor. In termites, however, no royal-recognition pheromones have been identified to date. In the current study, solvent extrac

Abstract:

Bombardment of pyrene-doped n-heneicosane (C21H44) in its orthorhombic solid phase with <1.3> MeV broadband X-rays results in the formation of both mono- and di-heneicosylpyrenes, whereas the same dose in liquid cyclohexane yields only monosubstituted pyrene. In both cases, the reaction efficiency decreases as pyrene concentration is increased from 10-5 to 10-2 M. Qualitatively, the overall attachment efficiency is higher in orthorhombic n-heneicosane than in liquid cyclohexane, but the selectivity of attachment is greater in cyclohexane. Differences between these results and those from

In order to learn of pyrolytic behavior of wheat straw multifunctional materials, the extractives of wheat straw biomass were adsorbed and determined by Py-GC-MS. And the main constituents were stigmasterol, vitamin e, campesterol, .gamma.-sitosterol, stigmasterol, 22,23- dihydro-, nonacosane, stigmastan-3,5,22-trien, heneicosane, lup-20(29)-en-3-one, 1,2- benzenedicarboxylic acid, buty l 2-methylpropyl ester, stigmast-4-en-3-one, stigmastan-3,5-diene, 4,22-stigmastadiene-3-one, cholest-5-en-3-ol (3.beta.)- , pyridine-3-carboxamide, oxime, etc.

Abstract:

Aim: The purposes of this study were to determine the anticancer activity of Xestospongia testudinaria sponge isolate and identify the responsible compounds. Materials and Methods: The metabolites were extracted using methanol maceration at room temperature. The separation and purification of metabolites were performed using fractionation and column chromatography. The toxicity was examined using the brine shrimp lethality assay, and the toxic isolates were tested for anticancer activity against HeLa cells. Gas chromatography-mass spectrometry analysis was used to identify the compounds in the

Abstract:

The GC-MS analysis of the essential oil from Tanacetum corymbosum revealed the presence of 38 compounds, including terpenes - germacrene D, (Z)-β-farnesene, g-elemene, β-caryophyllene, aliphatic - palmitic and linoleic fatty acids, fatty alcohol n-octadecanol, higher alkane n-heneicosane as the major constituents. The in vitro antimicrobial assessment of the ethanolic extract showed promising antibacterial/antifungal activities against five Gram-(+), Gram-(-) and phytopathogenic bacteria species and two fungi strains. The data obtained in this study may be useful both for researchers and for p

Abstract:

The aim of this study is to increase the phytochemical knowledge of South American bryophytes, particularly from those of the southern tip of the continent, due to the uniqueness of its poorly known bryoflora. Thirty-two specimens were analyzed using GC-MS technique. Most of the molecules found in the present bryophyte species belong to sesquiterpenes. In general, liverworts resulted to be richer in terpenoid compounds, while mosses in n-alkanes. Oplopanone, trans- chrysanthenyl acetate and 6,7-secoeudesm-7(11)-en-6-al are compounds here newly reported to the bryophytes. α-Ylangene and α-herbe

Abstract:

The essential oils of Jatropha intigrimma, J. roseae and J. gossypifolia (Euphorbiaceae) were analyzed employing GC/MS (Gas Chromatography coupled with Mass Spectrometry) analyses. A total of 95 volatile constituents were identified from J. intigrimma, J. gossypifolia and J. roseae essential oils, accounting for 91.61, 90.12, and 86.24%, respectively. Chemometric analysis using principal component analysis (PCA) based on the obtained GC data revealed the formation of three discriminant clusters due to the placement of the three Jatropha species in three different quadrants, highlighting the di

Abstract:

Polyethylene biodegradation results in the production of various by products. Polyethylene degradation by products were produced due to action of two potential fungal strains Aspergillus fumigates MF-14 and Aspergillus flavus MF-16) after sixty days of incubation with continuous shaking. Gas Chromatography-Mass Spectrometry analysis revealed a broad spectrum of polyethylene degraded byproduct produced by fungal strains during the degradation of polyethylene. Due to action of fungal strains Aspergillus fumigates MF-14 major polyethylene degrading product produced were heneicosane, 2-1-Hexacosan
