| Summary: | <i>Fragaria viridis</i> Weston or creamy strawberry is one of the less-known species of the <i>Fragaria</i> genus (Rosaceae family) with a wide distribution in Eurasia and is still in the shadow of more popular relatives <i>F. ananassa</i> (garden strawberry) or <i>F. vesca</i> (wild strawberry). Importantly, there is a lack of scientific knowledge on <i>F. viridis</i> compounds, their stability in the postharvest period, and bioactivity. In this study, metabolites of <i>F. viridis</i> fruits in three ripening stages were characterized with high-performance liquid chromatography with photodiode array and electrospray ionization triple quadrupole mass spectrometric detection (HPLC-PAD-ESI-tQ-MS). In total, 95 compounds of various groups including carbohydrates, organic acids, phenolics, and triterpenes, were identified for the first time. The quantitative content of the compounds varied differently during the ripening progress; some of them increased (anthocyanins, organic acids, and carbohydrates), while others demonstrated a decrease (ellagitannins, flavonols, etc.). The most abundant secondary metabolites of <i>F. viridis</i> fruits were ellagitannins (5.97-7.54 mg/g of fresh weight), with agrimoniin (1.41-2.63 mg/g) and lambertianin C (1.20-1.86 mg/g) as major components. Antioxidant properties estimated by in vitro assays (2,2-diphenyl-1-picrylhydrazyl radical (DPPH), 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) cation radical (ABTS), ferric reducing antioxidant power (FRAP), and oxygen radical absorbance capacity (ORAC)) showed good antioxidant potential in all ripening stages of <i>F. viridis</i> fruits. The pilot human experiment on the effect of <i>F. viridis</i> fruit consumption on the serum total antioxidant capacity confirmed the effectiveness of this kind of strawberry. Postharvest storage of ripe fruits at 4 °C and 20 °C lead to declining content in the majority of compounds particularly ascorbic acid, ellagitannins, and flavonols, with the most significant loss at room temperature storage. These results suggest that <i>F. viridis</i> fruits are a prospective source of numerous metabolites that have potential health benefits. |
