  • Abstract

    Anthocyanins are water-soluble red pigments. Anthocyanins have anticarcinogenic activity and reduce the risk of stroke and heart disease. Onion (Allium cepa L.) papery skin contains anthocyanin but rarely used. The aim of this study is to determine the effect of extraction methods and varieties on total anthocyanin content in acidified extract of onion papery skin varieties Bima Brebes and Maja Cipanas. Total anthocyanin contents are determinated by differential pH method. The anthocyanin was extracted with a mixture of 70% ethanol and 2N hydrochloric acid pH 1.0 by maceration, percolation, reflux extraction, and Soxhlet extraction. Total anthocyanin contents are more extracted in soaking method (maceration and reflux extraction) than flowing solvent method (percolation and Soxhlet extraction). Total anthocyanin contents of Maja Cipanas are more stable than Bima Brebes. The extraction method and onion varieties affect total anthocyanin contents.
