From the pollens of Aesculus hippocastanum , a new apocarotenoid was isolated as the main carotenoid and, based on the spectroscopic data, identified as (all‐ E ,3 R )‐3‐hydroxy‐6′‐apo‐ β ‐caroten‐6′‐al ( 4 , aesculaxanthin ). In addition, (all‐ E )‐lutein ( 3 ) and (all‐ E )‐ β ‐citraurin ( 5 ) were isolated. Furthermore, 6 ( aesculaxanthol ) was prepared by reduction of 4 with NaBH 4 and tentatively identified as natural carotenoid.
