The nature and the content of carotenoid pigments from faded leaves of Aesculus hippocastanum L.
AbstractFaded leaves of Aesculus hippocastanum L. harvested in October and November have a high and various content of carotenoids. The content of lutein and zeaxanthin is much higher in faded leaves than in the green ones, that is why they are recommended as an important natural source for extraction (at an industrial level) of the mentioned carotenoids. Faded leaves have a low biological value, because they have a low content of provitaminic A carotenoids. They have also a low content of hydrocarbon carotenoids, but a high hydroxylic and epoxydic content.
