Salt-tolerant plants, also known as halophytes, could provide a novel source of feedstock for biorefineries. After harvesting fresh shoots for food, the lignified fraction of J. Woods could be used to produce bioactive botanical extracts for high-value industries such as nutraceuticals, cosmetics, and biopharmaceuticals. The residual fraction after extraction can be further used for bioenergy or lignocellulose-derived platform chemicals. This work analysed from different sources and growth stages. After pre-processing and extractions, the obtained fractions were analysed for their contents of fatty acids, pigments, and total phenolics. Extracts were also evaluated for their in vitro antioxidant properties and inhibitory effect towards enzymes related to diabetes, hyperpigmentation, obesity, and neurogenerative diseases. The ethanol extract from the fibre residue and the water extract from completely lignified plants showed the highest concentration of phenolic compounds along with the highest antioxidant potential and enzyme-inhibitory properties. Hence, they should be further explored in the context of biorefinery.
耐盐植物，也被称为盐生植物，可为生物精炼厂提供一种新型原料来源。在收获新鲜嫩枝用于食用后，伍兹氏菊的木质化部分可用于生产用于营养保健品、化妆品和生物制药等高价值产业的生物活性植物提取物。提取后的残余部分可进一步用于生物能源或木质纤维素衍生的平台化学品。这项工作分析了来自不同来源和生长阶段的（样本）。经过预处理和提取后，对获得的部分进行脂肪酸、色素和总酚含量分析。还对提取物的体外抗氧化特性以及对与糖尿病、色素沉着、肥胖症和神经退行性疾病相关酶的抑制作用进行了评估。纤维残渣的乙醇提取物和完全木质化植物的水提取物显示出最高浓度的酚类化合物，同时具有最高的抗氧化潜力和酶抑制特性。因此，在生物精炼的背景下应对它们进行进一步探索。
