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.

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 current study is aimed to isolate endophytic actinobacteria from various medicinal plants for exploring its antimicrobial activity against clinical pathogens. Out of 50 actinobacterial cultures isolated eleven plants, 58 % the showed at least two out nine pathogens tested. Strain KCA1 Phyllanthus niruri leaves maximum zone inhibition all exhibited level metabolite production in solid state ...

A new actinomycete strain designated TN256, producing antimicrobial activity against pathogenic bacteria and fungi, was isolated from a Tunisian Saharan soil. Morphological and chemical studies indicated that strain TN256 belonged to the genus Streptomyces. Analysis of the 16S rDNA sequence of strain TN256 showed a similarity level ranging between 99.79 and 97.8% within Streptomyces microflavus...

In order to find out various bioactive compounds in flowers of Ageratum conyzoides, a weed the family Asteraceae, dried powdered were extracted analytical grade methanol and extract was examined by GC-MS. total, eight constituents identified. The predominant compound precocene II (59.50%). Three moderately abundant included ethanone, 1-(7-hydroxy-5-methoxy-2,2-dimethyl-2H-1-benzopyran-6-yl)- (9...

The current analysis was carried out to determine the chemical components in leaves of R. minima (L.) DC. GC-MS methanolic extract Minima indicated presence 19 compounds. prevailing compounds were 1Pentadecene (14.31), alpha. Bisabolol (10.39%), 1Heptadecene (9.78%), Cyclohexene,4 (1,5dimethyl1,4hexadienyl (7.06%), 3Hexadecene (Z) (8.10%), Caryophyllene (6.58%), Neophytadiene (5.16%), Humulene ...
