Differences in carotenoid composition in the integuments and eggs of flat bitterling, Paracheilognathus rhombea and Korean striped bitterling, Acheilognathus yamatsutae Mori were compared. Total carotenoid content in the integuments of male and female of flat bitterling and Korean striped bitterling were 2.3㎎%, 1.1㎎%, and l.9㎎%, 0.8㎎%, respectively. The composition of carotenoids in the integuments were very similar to each other, and the predominant carotenoids in the integuments of flat bitterling and Korean striped bitterling were lutein(48.0~39.2%), lutein epoxide(19.8~9.0%), trio1(15.7~5.6%), tunaxanthin(15.6~4.5%) and zeaxanthin(10.6~2.5%). In addition, α-cryptoxanthin(4.9~0.0%), cynthiaxanthin(4.8~0.0%), and β-carotene(3.4~0.0%) were present in small amounts. Total carotenoid contents in the eggs of flat bitterling and Korean striped bitterling were 1.8㎎% and 2.5㎎%, respectively. The major carotenoids in the eggs of flat bitterling were lutein(40.5%), lutein epoxide(34.4%) and tunaxanthin(12.1%) followed by zeaxanthin(6.8%), triol(1.4%), β-carotene(0.6%), and α-cryptoxanthin(0.5%). The carotenoids in the eggs of Korean striped bitterling were composed lutein(55.5%), lutein epoxide(24.5%), and zeaxanthin(7%). In addition, tunaxanthin(3.7%), triol(3.5%), α-cryptoxanthin(0.6%) and β-carotene (0.4%) were the minor components.
