This invention is directed to, inter alia, compounds, methods, systems, and compositions for the maintenance, enhancement, and expansion of hematopoietic stem cells derived from one or more sources of CD34+ cells. Sources of CD34+ cells include bone marrow, cord blood, mobilized peripheral blood, and non-mobilized peripheral blood. Also provided herein are compounds of Formula I ##STR00001## which are useful in maintaining, enhancing, and expanding of hematopoietic stem cells.

The present invention relates to a novel process for crystallizing high purity lutein and zeaxanthin esters from marigold oleoresin. In another aspect, the present invention relates to the removal of soft and hard waxes by adsorption on diatomaceous earth or other filter aid using acetone or other organic solvent. Another aspect of the present invention relates to achieving high-purity lutein and zeaxanthin esters, including purity levels that are about 90 to 95%.
