Analysis of Crocetins and Safranal Variations in Saffron (Crocus sativus) Stigma Samples and Dietary Supplements Using HPLC/UHPLC-PDA-MS: Chemical Profiling and Chemometric Analysis Using LC-QToF

Saffron, the world's most expensive spice, is made up of the dried and black stigma of Crocus sativus L. flowers of the Iridaceae family. Saffron products are used in the United States as diet supplements for mood augmentation, relaxation, weight loss, and metabolism promotion. The paper discusses two analytical techniques for the determination of crocetin esters, picrocrocin, safranal in saffron samples, and dietary supplements for inclusion in a monograph under development by the American Herbal Pharmacopoeia. In 16 of these items, no saffron compounds were discovered. The key adulterants discovered in dietary supplements were Flower of Carthamus tinctorius and fruit of Gardenia jasminoides. Principle component analysis was used to distinguish between saffron stigma samples and nutritional supplements. The results showed that commercial products are of variable quality, and the testing method is appropriate for quality testing of a variety of both raw materials and finished nutritional supplements.
