Carotenoid composition and spectroscopic characteristics were analyzed for Pterosperma cristatum Schiller, one of the most primitive known members of green algae. This alga contained a substantial amount of carotenoid esters, siphonaxanthin C14:1 trans-Delta2 ester and 6'-OH siphonaxanthin C14:1 trans-Delta2 ester, but lacked lutein. This is the first report of carotenoid C14:1 trans-Delta2 esters from phototrophic organisms. In vivo absorption spectra and excitation spectra of the cells revealed that these carotenoids absorbed blue-green light and could transfer energy to chl a. These carotenoids were concluded to function as antenna pigments in P. cristatum.
