Phenolic compounds present in rice have substantial antioxidant activity, which has contributed to its potential as a functional food. However, a gap in knowledge exists on how phenolic compounds in rice respond to variation in growing conditions, and the subsequent impact on their antioxidant activity. The current study investigated wholegrain pigmented rice varieties Yunlu29 and Purple, and a nonpigmented variety, Reiziq cultivated in Queensland (QLD) and New South Wales (NSW), Australia. The Queensland location in Mackay had a tropical climate and loamy soil, while the NSW location in Yanco had a temperate climate with clay soil.

水稻酚类化合物及其对生长条件下变异性的响应

大米中存在的酚类化合物具有强大的抗氧化活性，这有助于其作为功能食品的潜力。但是，关于水稻中酚类化合物如何应对生长条件的变化以及随后对其抗氧化活性的影响，知识上存在差距。当前的研究调查了全谷物有色水稻品种Yunlu29和Purple，以及无色素品种Reiziq，它们在澳大利亚的昆士兰州（QLD）和新南威尔士州（NSW）种植。麦凯的昆士兰州属热带气候，土壤肥沃，而扬科省的新南威尔士州属温带气候，土壤为粘土。
