Optimization of Ultrasound-Assisted Extraction of Polyphenol Content from Hairs (Waste).

The aim of this study was to achieve the best extraction efficiency of the hydroethanolic extract of hairs. The impacts of ethanol concentration, extraction time, and solvent /material ratio were studied in relation to the performance of extracts by ultrasonic extraction at 50 kHz and room temperature. All extracts were quantitatively characterized in terms of polyphenol content.

Phytochemical Screening, Polyphenols Content, Antioxidant Power, and Antibacterial Activity of from Morocco.

The aim of this study is to investigate antioxidant and antibacterial activities of the aqueous and hydroethanolic extracts for aerial parts of . Extracts were screened for their possible antioxidant activities by three tests: DPPH free radical-scavenging, reducing power, and molybdenum systems. The screening of antibacterial activity of extracts was individually evaluated against sixteen bacteria species using a disc diffusion method.
