neutrophils at concentration of 10μg/mL. From this fraction, six compounds (1-6) were isolated by the combination of different chromatographic methods. The structures of the compounds were determined by means of MS, 1D and 2D NMR spectroscopy. The results allowed the identification of the new 1,6-dihydroxy-2-keto-1,7-dimethyl-8-vinyl-1,2-dihydrophenanthrene (1) from the plant, named luzulin A. Chiral HPLC
本研究侧重于喀尔巴阡盆地本地的Luzula物种的抗炎筛选以及
生物活性指导下的Luzula luzuloides(Lam。)Dandy&Wilmott化合物的分离。测定了从卢祖拉(Luzula)物种制备的不同极性
提取物的抗炎特性。其中,在浓度为10μg/ mL的fMLP / CB诱导的人中性粒细胞中,L。luzuloides的
CH2Cl2可溶性级分对超
氧阴离子生成(99.39±0.37%)和
弹性蛋白酶释放(114.22±3.13%)具有较强的抑制作用。通过不同色谱方法的结合,从该馏分中分离出六种化合物(1-6)。化合物的结构通过MS,1D和2D NMR光谱法确定。结果可以鉴定出新的1,6-二羟基-2-酮-1,7-二甲基-8-
乙烯基-1,来自该植物的2-二氢
