Invention provides improvement in process of green crop fractionation to provide a route for production of novel phytochemical compositions or ingredients containing natural products contained in green plant material. Primary products of green crop fractionation produced in conventional process are fractionated further by using processes of oil extraction, aqueous acid extraction, aqueous alkali extraction, solvent extraction or are modified further in their form leading to products that are enriched in either oil soluble phytochemicals or water soluble phytochemicals. Most of these products can be used for human consumption directly or as an ingredient of a composition with a minimal further processing. Choice exists of using a process that totally avoids use of volatile organic solvents.
