Molecules, Vol. 25, Pages 3186: Antioxidant, Antimicrobial, and Other Biological Properties of Pompia Juice Molecules doi: 10.3390/molecules25143186 Authors: Antonio Barberis Monica Deiana Ylenia Spissu Emanuela Azara Angela Fadda Pier Andrea Serra Guy D’hallewin Marina Pisano Gabriele Serreli Germano Orrù Alessandra Scano Daniela Steri Enrico Sanjust Pompia is a Citrus species belonging to Sardinian endemic biodiversity. Health benefits were attributed to its flavedo rind extracts and essential oils while the juice qualities have never been investigated. In this paper, the antioxidant, antimicrobial, and other biological properties of Pompia juice were studied. A combined LCMS/electrochemical/biological approach was used to clarify a still debated phylogeny of this species and to explain the role of its juice phenolic compounds. A closer phylogenetic relationship with lemon and citron, rather than oranges was suggested. Sensors-based electrochemical measures, together with LCMS qualitative and quantitative analyses, revealed a high contribution of ascorbic acid and phenolics with low redox potential, isorhamnetin 3-O-rutinoside, diosmin, and diosmetin 6,8-diglucoside, to antioxidant capacity. The biological assays demonstrated a marked effect of low concentration of Pompia juice against reactive oxygen species (ROS) starting from 50 µg mL−1, and a moderate capacity to reduce ROS damages on cell membrane.
