L. is a Chinese herbal medicine with a long history, however, few studies have been performed on its chemical composition and active effects. In this study, we investigated the composition and antibacterial and antioxidant capacities of extracts obtained from L. phytosomes extracted with conventional solvents (water, methanol, and ethanol) and two different hydrogen bond donors (citric acid and 1,2-propanediol) modified with choline chloride-type deep eutectic solvents (DESs). The results show that extracts contained 253 compounds, including citric acid, ethyl maltol, and thymol. The highest total phenolic content (TPC) was obtained with a DES extraction method combining 1,2-propanediol and choline chloride (39.02 ± 7.08 mg gallic acid equivalent/g dried weight (DW). This shows the composition of as a natural product and the application of DESs in the extraction of active ingredients, demonstrating the potential of peat moss extracts in cosmetics and health products.
L. 是一种中草药，具有悠久的历史，但对其化学成分和活性作用的研究甚少。在这项研究中，我们研究了用常规溶剂（水、甲醇和乙醇）和两种不同氢键供体（柠檬酸和 1,2-丙二醇）改性的氯化胆碱型深共晶溶剂（DESs）提取的 L. 植物提取物的组成、抗菌和抗氧化能力。结果表明，提取物中含有 253 种化合物，包括柠檬酸、乙基麦芽酚和百里酚。DES 提取方法结合 1,2-丙二醇和氯化胆碱获得的总酚含量（TPC）最高（39.02 ± 7.08 mg 没食子酸当量/g 干重（DW）。这表明 L. 的组成是一种天然产物，DESs 在活性成分提取中的应用，展示了泥炭藓提取物在化妆品和保健品中的潜力。
