Vitamin K is a multi-function vitamin that has emerging roles in bone, brain and vascular health. Vitamin K composition data remain limited globally and Australia has lacked nationally representative data for vitamin K1 (phylloquinone) in horticultural commodities. Primary samples (n = 927) of 90 Australian-grown fruit, vegetable and nut commodities were purchased in three Australian cities. We measured vitamin K1/phylloquinone in duplicate in 95 composite samples using liquid chromatography with electrospray ionisation-tandem mass spectrometry. The greatest mean concentrations of vitamin K1/phylloquinone were found in kale (565 μg/100 g), baby spinach (255 μg/100 g) and Brussels sprouts (195 μg/100 g). The data contribute to the global collection of vitamin K food composition data. They add to the evidence that vitamin K1/phylloquinone concentrations vary markedly between geographic regions, supporting development of region-specific datasets for national food composition databases that do not yet contain data for vitamin K. Such data are needed globally.
维生素K是一种多功能维生素，在骨骼、大脑和血管健康方面发挥着越来越重要的作用。全球范围内维生素K的成分数据仍然有限，而澳大利亚缺乏园艺商品中维生素K1（叶绿醌）的全国代表性数据。在澳大利亚的三个城市购买了90种澳大利亚种植的水果、蔬菜和坚果商品的原始样本（n = 927）。我们使用液相色谱-电喷雾电离串联质谱法对95个复合样本中的维生素K1/叶绿醌进行了双份测定。维生素K1/叶绿醌平均浓度最高的是羽衣甘蓝（565μg/100g）、嫩菠菜（255μg/100g）和抱子甘蓝（195μg/100g）。这些数据有助于全球维生素K食物成分数据的收集。它们进一步证明了维生素K1/叶绿醌浓度在不同地理区域之间存在显著差异，支持为尚未包含维生素K数据的国家食物成分数据库开发特定区域的数据集。全球都需要此类数据。
