In general, polysaccharides tend to be more stable than alkamides and CAP, but their presence in Echinacea preparations is somewhat dictated by processing conditions. For example, one would expect dried plant material to contain the highest polysaccharide levels, followed by expressed juice preparation and alcohol tincture. Limited data are available regarding the effects of post-harvest handling and processing on polysaccharide levels.

Total sterol levels are affected by cultivar and region of cultivation. The ripening causes a slow continuous decrease of these compounds. Tocopherols are influenced by genetic and environmental factors, conditions of post-harvest fruit transportation and storage, and oil conservation. The smallest quantities were found in oil samples with high acidity and peroxide values.

Many plants owe their activity to compounds which are only formed as a result of post harvest enzyme effects. Examples include vanilla pods where there is no vanillin in the freshly picked pod it is formed only during fermentation of the pod which involves an enzymatic hydrolysis of a glycoside.
