New anthocyanins from purple pods of pea (pisum spp.)

Abstract

Two new anthocyanins were isolated from purple pods of pea (Pisum spp.). Their structures were identified as delphinidin 3-xylosylgalactoside-5-acetylglucoside and its deacetylated derivative by the usual chemical degradation methods and by spectroscopic methods such as UV-VIS, MS and NMR. Both pigments showed moderate stability and antioxidative activity in a neutral aqueous solution. © 2000, Taylor & Francis Group, LLC. All rights reserved.
