Elderberry growth phases represent an irreversible process involving a series of biochemical changes that have an extremely important impact on nutritional characteristics. The aim was to assess the impact of genotype and maturity stage on phenolic compounds, antioxidant capacity and mineral profile in plants harvested during different growth phases, from green elder flower buds to purple-black elderberries, including pollen, peduncles and seeds. Growth phases proved to have a greater influence compared to varieties. The green buds and flowers of both varieties had a high concentration of quercetin 3-rutinoside, also termed the key compound of the study. It was found that antioxidant activity varied in the following order: blooming elder flower pollen > white elder flower buds > blooming elder flowers. Based on these findings, several novel food ingredients and supplements could be obtained in order to develop innovative health-promoting products.
接骨木的生长阶段是一个不可逆的过程，涉及一系列对营养特性有极其重要影响的生化变化。目的是评估基因型和成熟阶段对不同生长阶段收获的植物中酚类化合物、抗氧化能力和矿物质成分的影响，这些阶段包括从绿色接骨木花芽到紫黑色接骨木果，还包括花粉、花柄和种子。结果表明，生长阶段比品种的影响更大。两个品种的绿色芽和花都含有高浓度的槲皮素3 - 芸香糖苷，也就是本研究的关键化合物。研究发现，抗氧化活性按以下顺序变化：盛开的接骨木花花粉＞白色接骨木花芽＞盛开的接骨木花。基于这些发现，可以获得几种新型食品成分和补充剂，以开发促进健康的创新产品。
