Sorghum, a globally grown gluten-free cereal, is used mainly as an animal feed in developed countries regardless of its potential for human consumption. In this study, we utilized nontargeted lipidomics to thoroughly analyze, compare, and characterize whole-grain lipids in six sorghum cultivars (cv) grown in a single field trial in Australia: Buster, Bazley, Cracker, Liberty, MR43, and Tiger. In total, 194 lipid molecular species representing five major lipid classes were identified. Multivariate analysis unveiled distinct lipid profiles among the cultivars. The most distinct lipid profile belonged to cv. MR43. The lower ω-6 to ω-3 ratio and optimal P/S ratio in cv. Bazley reflect this as a valuable source of balanced essential fatty acids in the diet. The novel bioactive lipids known as FAHFAs (fatty acid esters of hydroxy fatty acids) were identified and characterized in sorghum grains. These findings further emphasize the potential of whole-grain sorghum as a basis for new health-promoting food products.

高粱籽粒的非靶向脂质组学揭示了羟基脂肪酸的新型脂肪酸酯以及脂质谱的品种差异

高粱是一种全球种植的无麸质谷物，无论其供人类消费的潜力如何，在发达国家主要用作动物饲料。在这项研究中，我们利用非靶向脂质组学来彻底分析、比较和表征在澳大利亚单次田间试验中种植的六个高粱品种 (cv) 的全谷物脂质：Buster、Bazley、Cracker、Liberty、MR43 和 Tiger。总共鉴定出代表 5 个主要脂质类别的 194 种脂质分子。多变量分析揭示了品种之间不同的脂质谱。最独特的脂质谱属于 cv。 MR43。较低的 ω-6 与 ω-3 比率以及 cv 中的最佳 P/S 比率。贝兹利认为这是饮食中平衡必需脂肪酸的宝贵来源。在高粱籽粒中鉴定并表征了称为 FAHFAs（羟基脂肪酸的脂肪酸酯）的新型生物活性脂质。这些发现进一步强调了全麦高粱作为新型健康促进食品基础的潜力。
