Plants of the genus Allium such as onion and garlic are often consumed as a source of compounds which inhibit human platelet activity, with the goal of decreasing vascular disease. Antiplatelet activity in these plants is determined in part by native concentrations of organosulfur compounds. Evaluation of four onion genotypes grown in a field study at four US locations in 1994 demonstrated onions with mild flavor and low sulfur content exhibited significantly lower antiplatelet activity than those containing high levels of sulfur. Antiplatelet activity was significantly positively correlated with genotypically determined bulb sulfur content and dissolved solids, indicating these latter factors are good predictors of antiplatelet strength. These data demonstrate antiplatelet activity is genotype dependent and correlated with bulb sulfur content. Genotype and bulb sulfur content should be taken into account in studies assessing onion antiplatelet effects.
葱属植物，如洋葱和大蒜，常被作为抑制人体血小板活性的化合物来源食用，目的是降低血管疾病风险。这些植物中的抗血小板活性部分取决于有机硫化合物的天然浓度。1994年在美国四个地点进行的田间研究中，对四种洋葱基因型进行了评估，结果表明，味道清淡、硫含量低的洋葱的抗血小板活性明显低于硫含量高的洋葱。抗血小板活性与基因型确定的鳞茎硫含量和溶解固体显著正相关，表明后两个因素是抗血小板强度的良好预测指标。这些数据表明，抗血小板活性取决于基因型，且与鳞茎硫含量相关。在评估洋葱抗血小板作用的研究中，应考虑基因型和鳞茎硫含量。
