Influence of different cultivation systems on bioactivity of asparagus

Abstract

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.
