A simplified method for the HPLC resolution of α-carotene and -carotene (trans and cis) isomers
نویسندگان
چکیده
A new HPLC/DAD (Diode Array Detector) method is proposed for the identification of some carotene isomers. The operating conditions adopted permit the resolution of α-carotene, all-trans-β-carotene, 9-cis-β-carotene, 13-cis-β-carotene and 15-cis-β-carotene. Moreover, the chromatographic conditions reported are simplified in respect of those reported up to now. The method is applied to the determination of carotenoids in a dried Dunaliella salina extract, but it could be also applied to other organic matrices such as eggs.

Separation of beta-carotene and lycopene geometrical isomers in biological samples.
The analysis of beta-carotene and lycopene, the two predominant carotenoids in human serum and tissues, was extended to the level of geometrical (cis-trans) isomers by using an improved reversed-phase HPLC methodology. We separated five geometrical isomers of beta-carotene and seven of lycopene in human serum and tissues. 13-cis-beta-Carotene was identified as the predominant cisisomer in human...

For the quanti®cation of aand b-carotene including the cis-isomers of b-carotene in carrot juices and vitamin supplemented (ATBC) drinks, a rapid and artefact-free method was developed. The analytical procedure involves the extraction of carotenes with a mixture of acetone-hexane and their determination by HPLC using a C30 stationary phase. No saponi®cation prior to HPLC is required. The method...

A simple method for the simultaneous extraction and HPLC determination of provitamin A and vitamin E derivatives in vitamin supplemented (ATBC) drinks has been developed. The method allowed the complete separation of a-, b-, g-, and d-tocopherol, atocopheryl acetate, all-trans-a-carotene, all-trans-b-carotene, and the 9-cis and 13-cis isomers of b-carotene in less than 50 min. Recovery of analy...
