Etymology: Cryptoxanthin is a compound built from two Greek-derived pieces, and its name records a chemical puzzle. The first part, "crypto-", comes from the Ancient Greek "kruptos", meaning "hidden" or "concealed", the same root behind "crypt" and "cryptic". The second part, "xanthin", comes from the Greek "xanthos", meaning "yellow", which chemists used for a family of yellow plant pigments. Put together, the name points to a yellow pigment whose identity was once hidden. The name's sense is clear from the parts: chemists found a yellow pigment that had been concealed within the wider group of xanthophylls, the yellow carotenoids, and named it accordingly. The "xanthin" element places it among the yellow plant pigments, while "crypto-" marks it as the one that had escaped notice.

Synonyms: beta-cryptoxanthin, xanthophyll
