Abstract

Background: Blackberries and raspberries are nutritionally rich fruits, yet comprehensive studies assessing both mineral composition and antioxidant activity across diverse genotypes-particularly in Iran-remain limited. This study addresses this gap as the first to systematically evaluate twelve raspberry and blackberry cultivars cultivated in northern Iran, providing novel insights into genotype-specific variations in micronutrients (K, P, Ca, Mg, Fe, Mn, Cu) and antioxidant profiles (DPPH, FRAP).

Results: Distinct genotypic groupings emerged via cluster analysis, with blackberries (TripleCrown, French, Reuben) and raspberries (e.g., Saanich, KiwiGold) forming separate clusters. Principal component analysis (PCA) revealed three components explaining 77% of variance, highlighting strong correlations between genotype, minerals, and antioxidants. Potassium dominated mineral content (0.73-1.21%), with raspberry 'Summit' (1.21%) and 'KiwiGold' (1.08%) as top performers. Remarkably, the raspberry cultivar 'Saanich' demonstrated exceptional levels of iron (159.5 ppm) and manganese (10.5 ppm), surpassing those of other cultivars. Blackberries surpassed raspberries in antioxidant activity: DPPH values ranged from 184.43 µg/ml ('TripleCrown') to 316.02 µg/ml ('Encore'), while FRAP results showed blackberry 'TripleCrown' (17.28 mg Fe²⁺/g DW) outperforming raspberries by 36-57%.

Conclusion: This research highlights the potential of selected cultivars to enhance dietary intake of essential minerals, supporting both consumer health and breeding efforts aimed at improving nutritional quality in berry cultivars.

黑莓和覆盆子基因型的营养和抗氧化概况。

背景：黑莓和覆盆子是营养丰富的水果，但评估不同基因型的矿物质成分和抗氧化活性的综合研究仍然有限，特别是在伊朗。该研究解决了这一空白，首次系统评估了伊朗北部栽培的12个覆盆子和黑莓品种，为微量营养素（K， P, Ca, Mg, Fe, Mn, Cu）和抗氧化剂（DPPH， FRAP）的基因型特异性变化提供了新的见解。结果：通过聚类分析出现了不同的基因型分组，黑莓（TripleCrown, French, Reuben）和覆盆子（例如Saanich， KiwiGold）形成单独的簇。主成分分析（PCA）显示，三个成分解释了77%的方差，突出了基因型、矿物质和抗氧化剂之间的强相关性。钾主导矿物质含量（0.73-1.21%），其中覆盆子“Summit”（1.21%）和“KiwiGold”（1.08%）表现最好。值得注意的是，树莓品种“Saanich”的铁（159.5 ppm）和锰（10.5 ppm）含量异常高，超过了其他品种。黑莓的抗氧化活性超过覆盆子：DPPH值从184.43µg/ml （‘TripleCrown‘）到316.02µg/ml （’Encore’）不等，而FRAP结果显示黑莓‘TripleCrown’ （17.28 mg Fe²+ /g DW）比覆盆子好36-57%。结论：本研究突出了所选品种在提高膳食必需矿物质摄入量方面的潜力，为消费者健康和提高浆果品种营养品质的育种工作提供了支持。
