This investigation was designed to characterize phenolic metabolism of the olive cultivar, Hardy's Mammoth, by examining its constitutive tissues. The phenolic profiles of pulp, seed, stone, and new and old season leaves were monitored over two fruiting seasons, to investigate possible relationships between tissues and phenol content and to determine the impact of alternate fruit bearing. No major qualitative differences in phenolic composition were found between the various tissues; however, distinct differences between the tissues with respect to quantifiable phenols were established. Relationships between 2-(3,4-dihydroxyphenyl)ethyl (3E,4E)-4-formyl-3-(2-oxoethyl)hex-4-enoate ester, oleuropein, and hydroxytyrosol in pulp and leaf were identified and found to be related to alternate bearing. Concentrations of 5-caffeoylquinic acid in old season leaves differed dramatically between seasons, confirming earlier studies.
本研究旨在通过检测其组成组织来表征哈代巨象橄榄品种的酚类代谢。在两个结果季节监测果肉、种子、果核以及新叶和老叶的酚类概况，以研究组织与酚含量之间的可能关系，并确定隔年结果的影响。在不同组织之间未发现酚类组成的主要定性差异；然而，在可量化酚类方面确定了组织之间的明显差异。确定了果肉和叶片中2-(3,4-二羟基苯基)乙基(3E,4E)-4-甲酰基-3-(2-氧代乙基)己-4-烯酸酯、橄榄苦苷和羟基酪醇之间的关系，发现它们与隔年结果有关。老叶中5-咖啡酰奎尼酸的浓度在不同季节间差异显著，证实了早期研究。
