The objective of this study was to evaluate and compare, for the first time, white and black mulberry species in terms of main phytochemical, volatile composition and sensory profile characteristics in eight Spanish clones. The results showed that black and white mulberry species displayed significant different characteristics. PLS analysis has allowed grouping of the clones into four groups (i) MA1, MA2 and MN2, (ii) MN3 and MN4, (iii) MA3 and MA4, and (iv) MN1. Experimental results proved that Spanish mulberries have potential for fresh consumption due to their high antioxidant capacity (10.7-86.1 mg Trolox 100 g(-1)), polyphenol (76.7-180 mg gallic acid 100 g(-1)) and ellagic acid content (8.7-15.5 mg 100 g(-1)) as well as considerable amount of volatile compounds (35) with desirable attributes, which were scored high by a trained panel. Cultivars from the Morus nigra species seem to provide fruits with higher content of bioactive compounds and better aptitude for fresh consumption than Morus alba. Differences among the species should be attributed to genetics because they were cultivated under same conditions.
本研究旨在首次评估和比较白桑和黑桑品种在 8 个西班牙品种中的主要植物化学物质、挥发性成分和感官特性方面的差异。结果表明，黑桑和白桑品种表现出显著不同的特征。PLS 分析将克隆分为四组：(i) MA1、MA2 和 MN2，(ii) MN3 和 MN4，(iii) MA3 和 MA4，和 (iv) MN1。实验结果证明，西班牙桑椹具有新鲜食用的潜力，因为它们具有高抗氧化能力（10.7-86.1mg Trolox 100g(-1))、多酚（76.7-180mg 没食子酸 100g(-1))和鞣花酸含量（8.7-15.5mg 100g(-1))，以及相当数量的具有理想特性的挥发性化合物（35 种），这些化合物被训练有素的小组评为高分。与 Morus alba 相比，Morus nigra 品种的果实似乎具有更高的生物活性化合物含量和更好的新鲜食用适应性。种间差异应归因于遗传因素，因为它们是在相同条件下种植的。
