Isolation of 10′‐Apo‐β‐carotene‐10′‐ol and (3 R )‐10′‐Apo‐β‐carotene‐3,10′‐diol (Galloxanthin) from Rose Flowers The novel (all‐ E )‐10′‐apol‐β‐carotene‐10′‐ol ( 2 ) and (all‐ E ,3 R )‐10′‐apo‐β‐carotene‐3,10′‐diol ( 5 ) have been isolated from petals of one yellow species and various whitish or yellow blend varieties of rose cultivars. Each (all‐ E )‐compound is accompanied by a ( Z )‐isomer, probably the (9 Z )‐isomer. Diol 5 proved to be identical with galloxanthin, an apo‐10′‐carotenol previously isolated from the retina of chicken.
