Sea buckthorn (Hippophae rhamnoides L.) is an important plant with homology of medicine and food. It has rich nutritional medicinal properties. used as a traditional Chinese therapeutic functions invigorating spleen, relieving cough, eliminating food, phlegm, dispersing blood stasis, promoting circulation. This review comprehensively summarized flavonoids from sea L.), including extraction meth...

the perovskite-structured la2cuo4 nanoparticles have been synthesized via an ultrasonic-assisted co-precipitation route using octanoic acid as organic surfactant, and the phase composition, morphology, lattice parameters and size of nanoparticles are characterized through fourier transform infrared spectroscopy, x-ray diffraction, scanning electron microscopy and transmission electron microscop...

objective: the effects of dietary fish oil on semen quality and sperm fatty acid profiles during consumption of n-3 fatty acids as well as the persistency of fatty acids in ram’s sperm after removing dietary oil from the diet were investigated. materials and methods: in this experimental study, we randomly assigned 9 zandi rams to two groups (isoenergetic and isonitrogenous diets): control (ctr...

In this work, deep eutectic solvent (DES) combined with ultrasonic-assisted extraction was proposed to extract free seleno-amino acids from Cardamine hupingshanensis. The contents of in the were determined by high-performance liquid chromatography a fluorescence detector (HPLC-FLD). Response surface design used optimize conditions such as ultrasonic time, temperature, and liquid-solid ratio. re...

In the present study, ultrasound-assisted extraction of oil from rice bran was investigated through response surface methodology (RSM), where process variables were amplitude level (50–100%) and sonication time (5-30 min). It was found that all process variables had significant (p<0.05) effects on the response variable. A central composite design (CCD) was used to determine the optimum process ...

A set of 13 fatty acids was transformed into their phenacyl esters by reaction with phenacyl bromide in acetonitrile using 18-crown-6 as phase-transfer catalyst. Conditions for the RP-18 HPL chromatographic separation of most of the esters has been worked out. Using this standard the fatty acid spectra from skin surface sebum lipids of 17 test persons was taken after microwave-assisted hydrolys...

(1) Background: The extraction of fatty acids from microalgae and cyanobacteria is mostly performed with organic solvents laborious procedures. Microwave-assisted (MAE) can be a more effective environmentally friendly process than traditional (TE), which uses large volume solvent conduction heating. Freshwater phytoplankton inhabits diverse aquatic environments promising source green precursors...
