HPLC determination of carotenoid pigments in miscellaneous organic matrices

3 HPLC determination of carotenoid pigments in miscellaneous organic matrices 

Because of their considerable role in human wellfare, carotenoids have been measured not only in plants as primary sources and in human and animal tissues but also in a wide variety of other matrices to find new and economical sources for carotenoids. Thus, the carotenoid accumulation capacity of algae and microalgae have been vigorously investigated. A validated liquid chromatography-electrospray mass spectrometry method have been developed and employed for the separation and quantitative determination of 

CAROTENOID COMPOSITION (PERCENTAGE OF TOTAL S.E.) OF FULLY FORMED FEATHERS, BLOOD AND UNKERATINIZED LIPID FRACTIONS FROM MATURING FEATHER FOLLICLES IN FOUR PASSERINES THAT DISPLAY YELLOW PLUMAGE COLOURATION 

Some validation parameters of the method are listed in Table 2.26. It was further established that the sensitivity is higher under positive-ion than under negative conditions [69], 

New spectrophotometric and RP-HPLC methods were developed for the detection of adulteration in cochineals. The insects were cleaned over as sieve and dried at 60°C. The dried
