Pure trans - lutein ester composition and a manufacturing method thereof
The present invention provides a composition having a xanthophyll esters of high content of trans key rate xanthophyll ester components is high of the composition - a composition comprising lutein ester. The present invention also provides methods of making and using such compositions.
A high resolution, laser desorption time of flight mass spectrometer (LITOF-MS) was used to study lead borate glasses and crystals. This technique provides valuable information about glass structure, including the superstructural network units. Several structural units were identified and we found evidence of a lead substructure beginning to form in the glass with increased lead content.
