Abstract
Crocetin (1) and its glycosylesters are water-soluble carotenoids representing the main components of the yellow pigments of saffron and gardenia. Crocetin (2) is well absorbed, whereas crocetin digentiobiosyl ester (crocin (2)) is not absorbed in the intestine as such. The present study was aimed at determining the absorption profile of crocetin monogentiobiosyl ester (crocetin-MGE (3)) in rats. Rats were orally administered crocetin-MGE (3) over 7 days and sequentially crocetin (1) at the same dose after a wash-out period of 10 days. Rats were treated over seven days. The levels of crocetin-MGE (3) and crocetin (1) in plasma were evaluated following administration of crocetin-MGE (3) or crocetin (1). Crocetin-MGE (3) was obtained by controlled hydrolysis of crocin. The results demonstrated that crocetin-MGE (3) was rapidly absorbed with a mean time to reach maximum concentration (Tmax) of 0.5 h comparable to that obtained for crocetin (1). It is also partially metabolized to crocetin (1). Crocetin-MGE (3) is rapidly and efficiently absorbed as such and is metabolized to crocetin (1).
