Three new phenolic compounds 1–3 and twenty known ones 4–23 were isolated from the flowers of Bombax malabaricum. Their chemical structures were elucidated by spectroscopic analyses (IR, ESI-MS, HR-ESI-MS, 1D- and 2D-NMR) and chemical reactions. The antioxidant capacities of the isolated compounds were tested using FRAP and DPPH radical-scavenging assays, and compounds 4, 6, 8, 12, as well as the new
从木棉花中分离出三种新的酚类化合物 1-3 和二十种已知的酚类化合物 4-23。通过光谱分析(IR、ESI-MS、HR-ESI-MS、1D-和2D-NMR)和化学反应阐明了它们的化学结构。使用 FRAP 和 DPPH 自由基清除试验测试了分离化合物的抗氧化能力,化合物 4、6、8、12 以及新化合物 2 表现出比抗坏血酸更强的抗氧化活性。此外,通过CPE减少测定和斑块减少测定测试了所有化合物的抗RSV抗病毒活性。化合物 4、10、12 具有体外抗病毒活性,化合物 10 表现出有效的抗 RSV 作用,与阳性对照病毒唑相当。
