Techniques for Extracting Polyphenols from Coreopsis Tinctoria Nutt. Fruits
نویسندگان
چکیده
The literature does not present any information on ultrasonic assisted extraction of phenolic compounds from Coreopsis tinctoria Nutt. fruits using solvents with different polarities. The objective of this paper is to highlight the potential of ultrasound assisted extraction in the fast preparation of extracts rich in polyphenols of Coreopsis tinctoria Nutt. fruits in good yields. Several parameters that could affect extraction efficiency were evaluated. Finally, the results of the ultrasonic assisted extraction were compared with those obtained by using three extraction techniques, namely: maceration, refluxing and Soxhlet extraction.

Coreopsis tinctoria (snow chrysanthemum) has been reported to exert antihyperlipidemic effects. The present study aimed to identify the active compounds of Coreopsis tinctoria and to investigate the molecular mechanisms underlying its effects on lipid dysregulation by measuring lipid levels, reactive oxygen species, lipid peroxidation and fatty acid synthesis. The present results demonstrated t...
