the highest recorded amount appears to be specifically in the seed coat of black soybean ("glycine max" l. merr.) containing approximately 2 g per 100 g, in purple corn kernels and husks, and in the skins and pulp of black chokeberry ("aronia melanocarpa" l.) (see table). due to critical differences in sample origin, preparation, and extraction methods determining anthocyanin content, the values presented in the adjoining table are not directly comparable.
