The present study aimed to investigate the chemical composition, bioactive compounds, and antioxidant activity of two wild edible mushrooms, the honey fungus ( and the parasol mushroom (, collected from Northern Morocco (MA) and Portugal (PT). Those species were chosen due to their edibility, nutraceutical, and medicinal properties. Bioactive compounds (ascorbic acid, tannin, total phenolic, total flavonoid, β-carotene, and lycopene) and their antioxidant activity were determined by spectrophotometric methods. Herein, the fruiting body of the samples revealed a significantly higher amount of bioactive compounds, and values varied between the Moroccan and the Portuguese ones. Methanolic extracts shown a strong antioxidant capacity: Using DPPH free radical-scavenging activity radicals (IC 1.06-1.32 mg/mL); inhibition of β-carotene bleaching radicals (IC 0.09-0.53 mg/mL); and, reducing power radicals (IC 0.52-1.11 mg/mL). The mushroom species with the highest antioxidant capacity was from MA. Chemical composition was analyzed by GC-MS and LC-MS methodologies. GC-MS analysis showed that the most abundant biomolecules group was sugar compositions in the four samples (62.90%, 48.93%, 59.00%, and 53.71%) and the main components were galactitol 16.74%, petroselinic acid 19.83%, d-galactose 38.43%, and glycerol 24.43% in (MA), (PT), (MA), and (PT), respectively. LC-MS analysis of individual phenolic compounds revealed that vanillic acid (198.40 ± 2.82 µg/g dry weight (dw) and cinnamic acid (155.20 ± 0.97 µg/g dw) were the main compounds detected in , while protocatechuic acid (92.52 ± 0.45 and 125.50 ± 0.89 µg/g dw) was predominated in for MA and PT samples, respectively. In general, the results of this comparative study demonstrate that the geographic and climatic conditions of the collection site can influence biomolecule compounds and antioxidant properties of wild mushrooms. This study contributes to the elaboration of nutritional, nutraceutical, and pharmaceutical databases of the worldwide consumed mushrooms.
本研究旨在研究两种野生食用蘑菇——蜜环菌()和伞菌()的化学成分、生物活性化合物和抗氧化活性,这些蘑菇因其可食用性、营养和药用特性而被选中。通过分光光度法测定生物活性化合物(抗坏血酸、单宁、总酚、总类黄酮、β-胡萝卜素和番茄红素)及其抗氧化活性。在此,样品的子实体显示出生物活性化合物的含量明显较高,并且摩洛哥和葡萄牙的含量不同。甲醇提取物表现出很强的抗氧化能力:使用 DPPH 自由基清除活性自由基(IC 1.06-1.32mg/mL);抑制β-胡萝卜素漂白自由基(IC 0.09-0.53mg/mL);和,还原能力自由基(IC 0.52-1.11mg/mL)。抗氧化能力最高的蘑菇物种是来自 MA 的。通过 GC-MS 和 LC-MS 方法分析了化学组成。GC-MS 分析表明,四个样品中最丰富的生物分子组是糖组成(62.90%、48.93%、59.00%和 53.71%),主要成分是半乳糖醇 16.74%、生育酚 19.83%、D-半乳糖 38.43%和甘油 24.43%在 (MA)、 (PT)、 (MA)和 (PT)中,分别。对单个酚类化合物的 LC-MS 分析表明,香草酸(198.40±2.82μg/g 干重(dw)和肉桂酸(155.20±0.97μg/g dw)是 在 中检测到的主要化合物,而原儿茶酸(92.52±0.45 和 125.50±0.89μg/g dw)在 MA 和 PT 样品中分别占主导地位。一般来说,这项比较研究的结果表明,收集地点的地理和气候条件会影响野生蘑菇的生物分子化合物和抗氧化特性。本研究有助于编制全球食用蘑菇的营养、营养和制药数据库。
