The hydrodistilled oil of the aerial parts of Echiophora platyloba DC. was analyzed by GC and GC/MS. Ten components have been identified, of which the major constituents were found to be trans-b -ocimene (67.9%), 2-furanone (6.2%), myrcene (6.0%), linalool (3.1%), and cis-b -ocimene (2.3%).
چکیده سابقه و هدف: مطالعات حیوانی نشان داده اند که ایزومر trans -10, cis-12 اسید لینولئیک مزدوج با افزایش مقاومت به انسولین در ارتباط است، ولی یافته های پژوهش ها در ارتباط با تاثیر مخلوط برابر ایزومرهای trans -10, cis-12 cis-9,trans-11 بر عوامل خطر دیابت ناهمسو است. در این مطالعه، اثر مکمل اسید لینولئیک مزدوج بر میزان الگوی چربی سرم، قند ناشتا سرم، انسولین سرم، حساسیت و مقاومت انسولین زنان یائس...
In the title compound, C(21)H(15)NO(3), which is one of the photoreaction products of N-methyl-1,8-naphthalenedicarboximide with phenylacetylene, the cyclobutene and epoxy rings are trans to each other across the cyclohexene ring of the tetralin moiety. The dihedral angle between the mean planes of the cyclobutene and cyclohexene rings is 112.80 (2) degrees, while the latter makes a dihedral an...
microstructural investigation of low molecular weight 1,4-polybutadiene (1,4-pbd) was studied by 1h and 13c nuclear magnetic resonance spectroscopy (nmr). the isomer contents of 1,4-cis, 1,4-trans and 1,2- vinyl in polybutadiene microstructure were determined. the number average molecular weight for low molecular weight polybutadiene was measured by nmr techniques and comparison was made with g...
cis-4-Propylcyclohexanol is an important intermediate for synthesizing trans-2-(4-propylcyclohexyl)-1,3-propanediol, which widely used in the manufacture of liquid crystal displays. In this study, cis-4-propylcyclohexanol was prepared using a mutant alcohol dehydrogenase from Lactobacillus kefir (LK-TADH, A94T/F147L/L199H/A202L) coupled with glucose dehydrogenase. Using optimal catalytic condit...
first row transition metal complexes of phthalocyanine are employed as catalysts for the oxidation of cyclohexene and cyclooctene using iodosylbenzene and pentafluoroiodosyl benzene. the catalysis was performed in dichloromethane: methanol:water (80:18:2) solvent mixture. the products of the catalysis for cyclohexene are epoxycyclohexane, 2-cyclohexene-1-ol and 2-cyclohexene-1-one whereas for ...
Trans polyunsaturated fatty acids are produced during heat treatment of oils, such as deodorization and frying. The detailed metabolic pathways of these trans isomers are not fully understood. In the present work, the desaturation and chain elongation of [114 C]linoleic acid, 9 cis ,12 trans -18:2, 9 trans ,12 cis -18:2, a -linolenic acid, 9 cis , 12 cis ,15 trans -18:3 and 9 trans ,12 cis ,15 ...
Reaction of thionyl chloride with 2-acetyl-1- benzenesulfonylpyrrole semicarbazone (6 c) gave 4 - (1- benzenesulfonyl-2 - pyrrolyl) - 1, 2, 3 -thiadiazole (lc). Selenium dioxide oxidation of 2-acetylpyrazine semicarbazone (10) in acetic acid afforded 4- (2-pyrazinyl) - 1, 2, 3- selenadiazole (4). Reaction of thionyl chloride with compound 10 gave 4- (2-pyrazinyl) - 1, 2, 3- thiadiazole (3)....
