Carotenoids in sea buckthorn ( Hippophae rhamnoides L.) berries during ripening and use of pheophytin a as a maturity marker.

摘要: Four cultivars of sea buckthorn berries were analyzed for their carotenoid and chlorophyll contents during ripening in three consecutive years. The different carotenoids generally increased concentration comprised from 120 to 1425 μg/g DW total (1.5−18.5 mg/100 g FW) depending on cultivar, harvest time, year. GLM analyses revealed the effect cultivar be considerably larger than that year time. content pheophytin a, a derivate, steadily decreased berry ripening. Pheophytin therefore acted as marker degree was used here convert date into an estimated
