The object of this study is the flowers of Kazakhstan species of “AkMai” safflower, collected in the flowering stage in Southern Kazakhstan. Volatile oil was carry out to study the component composition of Kazakhstan “AkMai” safflower flowers. The composition of the volatile oil obtained from the dried flowers of Carthamus tinctorius L. growing in Kazakhstan. Pale yellow oily extracts were obta...

Background: Essential oil content and composition in medicinal and aromatic plants is highly affected by both biotic and abiotic factors. Objective: To investigate the effects of drought stress, zeolite and bio-fertilizers on morphological characteristics and essential oil constituents in Dracocephalum moldavica L. Methods: This experiment was conducted in the form of split factorial based on...

Szechuan peppers, famous for their unique sensation and flavor, are widely used as a food additive and traditional herbal medicine. Zanthoxylum bungeanum and Z. armatum are both commonly recognized as Szechuan peppers, but they have different tastes and effects. The chemical components, genetic characteristics, and suitable habitat of six cultivars were analyzed in this study. The results indic...

The essential oil of Helichrysum italicum (Roth) G. Don (everlasting or Immortelle essential oil) was isolated by hydrodistillation and analysed by GC and GCMS. Forty four compounds were identified. The main components were alpha-pinene(12.8%), 2-methyl-cyclohexyl pentanoate (11.1 %), neryl acetate (10.4%), 1,7-di-epi-alpha-cedrene (6.8%) and other compounds. The oil was fractionated and ester-...

The volatile oil obtained by hydrodistillation of the petals of Rosa damascena Mill. (Rosaceae) was analyzed by gas chromatography and gas chromatography/mass spectrometry (GC/MS). The yield of the oil was 0.12 % (v/w). Fifty compounds representing 99.06 % of the oil were characterized. The volatile oil was found rich in sesquiterpenes and aliphatic components, consisting of two monoterpenic es...

Members of the genus Schinus mainly S. terebinthifolius (Brazilian pepper tree) and S. molle (Peruvian pepper tree) have long been recognized as a consolidate sources of functional ingredients namely essential oils and phenols. Despite the substantial data on the volatile oil constituents of their fruits, the leaf volatile fraction has not received much interest. Consequently, the aim of the pr...

HFCI34a was selected for the alternative refrigerant for CFC12 because of its excellent properties like thermodynamics. But there were several problems like immiscibilitiy with oil to replace CFC12 by HFC134a. In order to solve these problems, we developed new polyol ester refrigeration oil which had good miscibility with HFC134a and excellent thermal stability and lubricity as well. To apply p...

BACKGROUND Brucellaabortus is a gram-negative facultative intracellular bacterium that can cause a highly contagious disease in sheep, goats, cattle and one-humped camels. It is responsible for one of the most important zoonosis in human. The aim of this study was to evaluate the role of Mentha piperita, Origanum majorana, Citrus lemon, Cinnamomum verum and Myristica fragrans essential volatile...

Fuel properties of loofah oil and its ethyl ester blended with diesel were experimentally determined. Biodiesel blends (10, 20, 30, 40, 50, 60, 70, 80, 90 and 100%) of loofah oil and its ethyl ester by volume with diesel was used. The fuel properties of the biodiesel blends were determined according to American Society for Testing and Materials (ASTM) standards. Pure Automotive Gas Oil (AGO) wa...

The chemical composition of the volatile oils from five Anacardiaceae species and their activities against Gram positive and negative bacteria were assessed. The peroxidative damage within bacterial cell membranes was determined through the breakdown product malondialdehyde (MDA). The major constituents in Anacardium humile leaves oil were (E)-caryophyllene (31.0%) and α-pinene (22.0%), and in ...
