Chemical examination of the methanolic extract from the stem bark of Daphne feddei led to the isolation of three new dicoumarin glucosides (1–3), and eight known coumarins, dicoumarins and dicoumarin glucosides. Their structures were elucidated by extensive analysis of spectral data and comparison with the literature values. All compounds were tested for inhibitory activity against lipopolysaccharide-induced
从树皮的甲醇提取物的理化检验达芙妮feddei导致了三个新双香豆素苷(隔离1 - 3),以及8个已知香豆素,dicoumarins和双香豆素苷。通过对光谱数据进行广泛分析并与文献值进行比较,阐明了它们的结构。测试了所有化合物对RAW 264.7巨噬细胞中脂多糖诱导的NO产生的抑制活性,化合物4和5表现出有效的抑制活性,IC 50值分别为0.161和0.127μM。
