Extraction of Polyphenols and Anthocyanins from the Jambul (Syzygium cumini) Fruit Peels
In this work, the feasibility of using ultrasound alone and in combination with other techniques for the extraction of polyphenols and anthocyanins from jambul (Syzygiu mcu mini) peels was evaluated. The results were compared with conventional techniques (agitated bed and So xh let ext raction techniques) based on total extract y ields, total phenolic and monomeric anthocyanin concentrations in the extracts and the relative yields of these compounds. Ultrasound-assisted extract ion was more efficient and selective for the ext raction of anthocyanins than both conventional methods. When a combination of ultrasound and agitated bed extraction was used, a significant increase in total yields, and both polyphenol and anthocyanin concentrations was achieved. Electrospray Ionization Tandem Mass Spectrometry analysis indicated that diglycosideanthocyanins (cyanidin-3,5-dig lycoside, peonidin-3,5-dig lycoside, delphinidin-3,5-d iglycoside, petunidin-3,5-diglycoside and malvidin-3,5-diglycoside) were the main polyphenols present in the samples.
