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.

摘要

背景

黑莓和树莓是营养丰富的水果，但评估不同基因型（尤其是在伊朗）的矿物质组成和抗氧化活性的综合研究仍然有限。本研究填补了这一空白，首次系统评估了伊朗北部种植的12个树莓和黑莓品种，为微量营养素（钾、磷、钙、镁、铁、锰、铜）和抗氧化特性（DPPH、FRAP）的基因型特异性差异提供了新的见解。

结果

通过聚类分析出现了不同的基因型分组，黑莓（三冠王、法国、鲁本）和树莓（如萨尼奇、奇异果金）形成了单独的聚类。主成分分析（PCA）揭示了三个成分解释了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。钾在矿物质含量中占主导地位（0.73-1.21%），树莓品种“顶峰”（1.21%）和“奇异果金”（1.08%）表现最佳。值得注意的是，树莓品种“萨尼奇”表现出极高的铁（159.5 ppm）和锰（10.5 ppm）含量，超过了其他品种。黑莓的抗氧化活性超过树莓：DPPH值范围为184.43 μg/ml（“三冠王”）至316.02 μg/ml（“安可”），而FRAP结果显示黑莓“三冠王”（17.28 mg Fe²⁺/g DW）比树莓高出36-57%。
