摘要：

This study aimed to explore the main biochemical components and the antioxidant capacity of five strawberry tree fruits using three antioxidant essays within the ecotypic comparison scheme, to find out the most valuable fruit presenting disease-preventing properties. Total phenols, total flavonoids, total anthocyanins, antioxidant activity (DPPH, ABTS, and beta-Carotene bleaching assays), pH, titratable acidity, soluble solids, and moisture content were investigated in five strawberry tree genotypes belonging to several areas in Morocco. Phenolic compounds were also identified using high performance chromatography (HPLC), with a diode array detector (DAD). High significant differences (p < 0.05) were revealed among the examined genotypes regarding their total phenols (25.37-39.06 mg gallic acid equivalents (GAE)/g Dry weight (DW), total flavonoids (3.30-7.07 mg RE/g Dry weight (DW), total anthocyanins (0.15-0.64 mg cya-3-glu/100g Dry weight (DW), pH (2.44-3.92), titratable acidity (0.65-1.01 g malic acid/100g Fresh weight (FW), and soluble solids (14.83-18.53%). The average radical scavenging capacity, assessed using three methods, exhibited the following concentration ranges: 3.33-21.08, 2.25-19.58, and 1.08-13 mg Ascorbic Equivalent (AAE/g Dry weight(DW) for the DPPH scavenging test, ABTS, and beta-carotene bleaching, respectively. Seventeen phenolic compounds were identified in sampled cultivars. Gallocatechol and catechin were found to be the major phenolic compounds. The correlation matrix revealed significant correlations among investigated variables, particularly ABTS and DPPH. The principal component analysis showed that the first three components formed 90.25% of the total variance. The following variables: chlorogenic acid, ellagic acid derivative, ellagic acid, rutin, and cyanidin-30.5-diglucoside, were the most involved in the total variance. The results revealed highly promising physico-biochemical profiles within the studied strawberry tree genotypes.
