The chemical constituents of victoria plums : Preliminary qualitative analysis

Abstract

Abstract Victoria plums from a number of sources, and including samples from trees on different rootstocks, have been examined with a view to identifying their major and minor constituents. The red pigment common to all samples is cyanidin‐3‐monoglucoside, and obvious differences in colour appear to be due to variations in the amounts of green or brown pigments. The present paper concerns the essentially qualitative preliminary examination of the fruits, which is to be followed by quantitative analyses continued over several years.
