The phenolics of fruits. VII. The phenolics of cherries and plums and the changes in catechins and hydroxycinnamic acid derivatives during the development of fruits.
Quantitative data of hydroxycinnamic acids, hydroxybenzoic acids and hydroxycoumarins (after hydrolysis of derivatives) and of catechins are given. -Large quantities of catechins and hydroxycinnamic acid derivatives are found in the young fruit. Related to mg per kg fresh weight these concentrations soon decline sharply, especially during the progressive growth of the fruits. Related to mg per fruit, the concentrations of catechins increase progressively with fruit development, showing a loss when reaching maturity. The concentrations of hydroxycinnamic acids increase in a similar manner, but show in part a remarkable loss when examined after removal of the harder seeds.
