Vitamin D has previously been quantified in some plants and algae, particularly in leaves of the Solanaceae family. We measured the vitamin D content of Australian native food plants and Australian-grown edible seaweed. Using liquid chromatography with triple quadrupole mass spectrometry, 13 samples (including leaf, fruit, and seed) were analyzed in duplicate for vitamin D₂, vitamin D₃, 25-hydroxyvitamin D₂, and 25-hydroxyvitamin D₃. Five samples contained vitamin D₂: raw wattleseed () (0.03 µg/100 g dry weight (DW)); fresh and dried lemon myrtle () leaves (0.03 and 0.24 µg/100 g DW, respectively); and dried leaves and berries of Tasmanian mountain pepper () (0.67 and 0.05 µg/100 g DW, respectively). Fresh kombu () contained vitamin D₃ (0.01 µg/100 g DW). Detected amounts were low; however, it is possible that exposure to ultraviolet radiation may increase the vitamin D content of plants and algae if vitamin D precursors are present.
先前已在一些植物和藻类中定量了维生素 D，特别是在茄科植物的叶子中。我们测量了澳大利亚本土食用植物和澳大利亚种植的可食用海藻中的维生素 D 含量。使用带有三重四极杆质谱的液相色谱法，对 13 个样本（包括叶、果和种子）进行了两次分析，以检测维生素 D₂、维生素 D₃、25-羟维生素 D₂ 和 25-羟维生素 D₃。有 5 个样本含有维生素 D₂：生胡芦巴种子（0.03μg/100g 干重（DW））；新鲜和干燥的柠檬香桃木（）叶（0.03 和 0.24μg/100g DW，分别）；和干燥的塔斯马尼亚山胡椒（）叶和浆果（0.67 和 0.05μg/100g DW，分别）。新鲜昆布（）含有维生素 D₃（0.01μg/100g DW）。检测到的含量很低；但是，如果存在维生素 D 前体，则暴露于紫外线辐射可能会增加植物和藻类中的维生素 D 含量。
