Separation of ethyl acetate fractionation of Dracocephalum peregrinum afforded three new flavonoid glucosides (1—3), and a new cyanogenic glucoside (4). Their structures were elucidated based on HR-electron spray ionization (ESI)-MS, EI-MS, UV, IR, 1D-, and 2D-NMR data. 1—4 were tested in vitro for their antiinflammatory activity against the RAW 264.7, 293 cells. Among the compounds tested, 1—4 shown good antiinflammatory activity at 100 μg/ml by the measurement of nitric oxide (NO) in lipopolysaccharide (LPS) activated macrophages. But only 2 and 3 shown weak antiinflammatory activity at 100 μg/ml during the nuclear factor (NF)-κB activation assay.
分离龙蒿属植物的乙酸乙酯馏分得到三种新的黄酮苷(1-3)和一种新的氰基苷(4)。根据HR-电子喷雾电离(ESI)-MS、EI-MS、UV、IR、1D-和2D-NMR数据阐明了它们的结构。1-4在体外对RAW 264.7、293细胞进行了抗炎活性测试。在测试的化合物中,1-4在100μg/ml时通过测量脂多糖(LPS)激活的巨噬细胞中的一氧化氮(NO)显示出良好的抗炎活性。但在核因子(NF)-κB激活试验中,只有2和3在100μg/ml时显示出微弱的抗炎活性。
