Evaluation of functional and bioactive compounds of Asparagus officinalis L. growing in conventional and organic greenhouse and conventional open - field farming was the aim of this research. Polyphenols in cladodes grown conventionally were higher than organic. Flavonoids and carotenoids were the highest in cladodes in open field. Organic spears were richer in total phenolics (+6.9% and +19.1%) and flavonoids (+4.7% and 16.8%) and showed higher in vitro averages of antioxidant activities by three radical scavenging assays (+12.5% and+ 22.2%) than conventional. Partial differentiation of organically and conventionally grown samples was proved by multivariate statistics. The binding properties of polyphenols to HSA were relatively high in comparison with other plants. A strong positive correlation of binding properties and bioactivity of asparagus was estimated. All new found aspects for the first time lead to recommendation of inclusion of all investigated asparagus plants into the human diet in a wider scale.
本研究旨在评估常规温室和有机温室以及常规露天种植的天门冬中功能性和生物活性化合物。常规种植的芦笋中的多酚含量高于有机种植。在露天种植的芦笋中，类黄酮和类胡萝卜素含量最高。有机芦笋的总酚（+6.9%和+19.1%）和类黄酮（+4.7%和 16.8%）含量更高，三种自由基清除测定法的体外平均抗氧化活性也更高（+12.5%和+22.2%）。多元统计证明了有机和常规种植样品的部分分化。与其他植物相比，天门冬中多酚与 HSA 的结合特性相对较高。估计了芦笋结合特性和生物活性之间存在强正相关。所有新发现的方面都首次建议将所有研究的天门冬植物纳入更广泛的人类饮食中。
