The paper aims to compare the chemical compositions of essential oils and anatomical properties secretory structures differences between R. damascena which is cultivated in Iğdır Isparta (EOI1, EOI2, EOIg). GC/ MS GC-FID were utilized for analysis. Nonadecane (31.0%), heneicosane (21.1%), citronellol (16.8%), 1-nonadecene (6.2%) primal constituents EOI1. (29.3%), (17.6%), (18.6%), 1- nonadecene...

the essential oil obtained by hydrodistillation of the aerial parts of rosa damascenea mill. was analyzed by gc/ms. the yield of the oil was 0.16% (v/w). among twenty five components, eight components, representing 99.98% of the oil, were characterized. nonadecane (39.73%), heneicosane (32.38%), docosane (7.34%), citronellol (6.14%) and 9-nonadecene (5.69%), were found to be major constituents.

D ufour’s gland secretion o f several species o f the desert ant C ataglyphis from different geo­ graphical localities was analyzed. The secretions constituted mostly o f alkanes ranging from undecane to nonadecane. Species specificity is expressed as variations in the major component as well as the relative intensities o f the additional constituents. Phylogenetically related species that are ...

Damask rose (Rosa damascena Mill.) is one of the most high-value essential oil-bearing plants in the world. However, the flower yield and quality of essential oil of R. damascena are largely influenced by the pruning practices and balanced supply of plant nutrition. The objective of this study was to test the hypothesis whether the pruning system and foliar fertilization of MgSO4 would influenc...

HIGHLIGHTS Streptomyces sp. nkm1 was isolated from a marine soil sample and identified using morphological molecular techniques. had the highest antifungal activity against some plant pathogenic fungi on M6 medium. On Aspergillus flavus, minimum inhibitor concentration of ethyl acetate Crude extract more effective. The GC-MS analysis revealed 26 components, with nonadecane being most important ...

We designed a two-step Pickering emulsification procedure to create nano-encapsulated phase changing materials (NEPCMs) using a method whose simplicity and low energy consumption suggest promise for scale-up and mass production. Surface-modified amphiphilic zirconium phosphate (ZrP) platelets were fabricated as the Pickering emulsifiers, nonadecane was chosen as the core phase change material (...
