For the first time, (family: Orchidaceae) has been investigated for its phytochemical, antioxidant, anti-inflammatory, and thrombolytic properties. All phytochemicals studied were identified in varying degrees during qualitative screening. In quantitative screening, a maximum of 106.02 ± 0.08 mg/g alkaloids (root), 179.67 ± 8.83 mg/g phenols (stem), 17.34 ± 0.88 mg/g flavonoids (stem), 73.67 ± 1.76 mg/g tannins (stem), and 180.04 ± 0.02 g/mL proteins (root) were detected. Antioxidant, anti-inflammatory, and thrombolytic properties were investigated using a free-radical scavenging assay, heat-induced albumin denaturation assay, and blood clotting inhibition assay. The root extracts had the most effective antioxidant (IC = 67.98 g/mL) and anti-inflammatory (IC = 60.86 g/mL) properties, whereas the stem extracts had the most effective thrombolytic property (IC = 163.8 g/mL). The bioactivities studied also had a significant positive relationship ( = 0.9; < 0.05) with the amount of phenolics and tannins.
首次对(兰科)进行了植物化学、抗氧化、抗炎和溶栓特性的研究。在定性筛选过程中,所有研究的植物化学物质都得到了不同程度的鉴定。在定量筛选中,检测到的生物碱含量最高为106.02±0.08毫克/克(根)、酚类为179.67±8.83毫克/克(茎)、黄酮类为17.34±0.88毫克/克(茎)、单宁为73.67±1.76毫克/克(茎)、蛋白质为180.04±0.02克/毫升(根)。使用自由基清除试验、热诱导白蛋白变性试验和凝血抑制试验研究了抗氧化、抗炎和溶栓特性。根提取物具有最有效的抗氧化(IC = 67.98克/毫升)和抗炎(IC = 60.86克/毫升)特性,而茎提取物具有最有效的溶栓特性(IC = 163.8克/毫升)。所研究的生物活性与酚类和单宁的含量也具有显著的正相关关系( = 0.9; < 0.05)。
