Phenolic compounds can provide antioxidant health benefits for humans, and foods such as lentils can be valuable dietary sources of different subclasses of these secondary metabolites. This study used LC-MS analyses to compare the phenolic profiles of lentil genotypes with four seed coat background colors (green, gray, tan, and brown) and two cotyledon colors (red and yellow) grown at two locations. The mean area ratio per mg sample (MARS) values of various phenolic compounds in lentil seeds varied with the different seed coat colors conferred by specific genotypes. Seed coats of lentil genotypes with the homozygous recessive tgc allele (green and gray seed coats) had higher MARS values of flavan-3-ols, proanthocyanidins, and some flavonols. This suggests lentils featuring green and gray seed coats might be more promising as health-promoting foods.
酚类化合物可为人类提供抗氧化的健康益处，而诸如小扁豆之类的食物可能是这些次生代谢产物不同亚类的宝贵膳食来源。本研究采用液相色谱 - 质谱分析方法，比较了在两个地点种植的、具有四种种皮背景颜色（绿色、灰色、棕褐色和棕色）和两种子叶颜色（红色和黄色）的小扁豆基因型的酚类物质谱。小扁豆种子中各种酚类化合物的每毫克样品平均面积比（MARS）值因特定基因型赋予的不同种皮颜色而异。具有纯合隐性tgc等位基因的小扁豆基因型（绿色和灰色种皮）的种皮中黄烷 - 3 - 醇、原花青素和一些黄酮醇的MARS值较高。这表明具有绿色和灰色种皮的小扁豆作为促进健康的食物可能更具前景。
