Spinach leaves, goji berries and quinoa seeds are claimed to have a great nutraceutical potential due to their high content of compounds providing benefits for human health, such as amino acids, polyunsaturated fatty acids, carotenoids, betaine, vitamins, fibre, minerals and polyphenols. Samples of these plants were extracted with different solvent mixtures (e.g. EtOH, HO/EtOH 3:7 and HO/EtOH 7:3) and extractions were accomplished using a microwave apparatus. Subsequent UHPLC analysis and photodiode array detection were employed for the quantification of biologically active compounds like 7-isopentenyloxycoumarin, auraptene, umbelliprenin, boropinic acid and 4'-geranyloxyferulic acid. EtOH was found to be the best solvent in terms of extractive yields and the above-mentioned phytochemicals were recorded in the concentration range 2.01-49.22 µg/g dry extract. The findings depicted herein revealed that spinach, goji and quinoa are good sources of oxyprenylated umbelliferone and ferulic acid derivatives.
菠菜叶、枸杞和藜麦种子因含有多种对人体健康有益的化合物而具有巨大的营养潜力，如氨基酸、多不饱和脂肪酸、类胡萝卜素、甜菜碱、维生素、纤维、矿物质和多酚。这些植物的样品分别用不同的溶剂混合物（如 EtOH、HO/EtOH3:7 和 HO/EtOH7:3）提取，并使用微波设备进行提取。随后采用 UHPLC 分析和光电二极管阵列检测法对 7-异戊烯氧基香豆素、珊瑚菜内酯、 Umbelliprenin、Boropinic acid 和 4'-香叶基阿魏酸等生物活性化合物进行定量分析。结果表明，EtOH 在提取产率方面表现最佳，上述植物化学物质的浓度范围为 2.01-49.22μg/g 干提取物。本研究结果表明，菠菜、枸杞和藜麦是 oxyprenylated umbelliferone 和阿魏酸衍生物的良好来源。
