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.
