Melon is a valuable crop that generates significant by-products during consumption and processing. Among these, seeds are rich in phenolic compounds and might be used to produce sprouts with increased content of these bioactive substances. This study evaluated phenolic compounds (PhCs) in sprouts of two melon cultivars, Thales and SV9424ML, obtained from seeds having different germination speeds, thus harvested at 6 and 14 days after sowing (DAS). A factorial combination of cultivar and harvest time was tested in a completely randomized design with four replicates. Thales produced more ready-to-eat sprouts at 6 DAS than SV9424ML (64.0% vs. 46.7%). Sprouting significantly increased total PhCs content, particularly flavonoids, with Thales showing higher values than SV9424ML (50.2 vs. 32.6 mg kg DW). Phenolic profiles significantly varied among cultivars and harvests. Sprouts at 6 DAS had more total hydroxybenzoic acids and flavonoids, while 14 DAS sprouts were richer in hydroxycinnamic acids. Significant differences between harvest dates were observed in the concentrations of protocatechuic, vanillic (VanA), -coumaric (-CouA), ferulic (FerA) acids, and orientin (Ori) for Thales, and of VanA, -CouA, FerA, and Ori for SV9424ML. Results are encouraging, but future investigations are essential to understand whether these sprouts can be suitable for fresh consumption, food supplements, or phytochemical extraction.
甜瓜是一种重要的作物，在食用和加工过程中会产生大量副产品。其中，种子富含酚类化合物，可用于培育这些生物活性物质含量更高的豆芽。本研究评估了从发芽速度不同的种子中获得的两个甜瓜品种（泰勒斯和SV9424ML）豆芽中的酚类化合物（PhCs），这些种子分别在播种后6天和14天收获。采用完全随机设计，对品种和收获时间的析因组合进行了四次重复试验。泰勒斯在播种后6天比SV9424ML产生了更多即食豆芽（64.0%对46.7%）。发芽显著提高了总PhCs含量，尤其是黄酮类化合物，泰勒斯的含量高于SV9424ML（50.2对32.6毫克/千克干重）。酚类物质谱在品种和收获期之间存在显著差异。播种后6天的豆芽中总羟基苯甲酸和黄酮类化合物含量更高，而播种后14天的豆芽中羟基肉桂酸含量更丰富。在泰勒斯的原儿茶酸、香草酸（VanA）、对香豆酸（-CouA）、阿魏酸（FerA）和荭草素（Ori）以及SV9424ML的VanA、-CouA、FerA和Ori浓度方面，收获日期之间存在显著差异。结果令人鼓舞，但未来仍需进行研究，以了解这些豆芽是否适合新鲜食用、作为食品补充剂或用于植物化学物质提取。
