摘要
目的:研究独一味地上部分的化学成分。方法:应用多种色谱技术分离纯化,根据理化性质及波谱分析鉴定化合物的结构。结果:从独一味地上部分的乙醇提取物中分离得到了12个化合物,分别鉴定为木犀草素(1)、木犀草素7-O-β-吡喃葡萄糖苷(2)、芹菜素(3)、芹菜素7-O-β-D-吡喃葡萄糖苷(4)、芹菜素7-O-(6″-反式-对-香豆酰基)-β-D-半乳糖苷(5)、小麦黄素(6)、刺槐素(7)、芫花素(8)、独一味素A(9)、独一味素B(10)、山栀苷甲酯(11)及丁香酸(12)。结论:化合物5-8及12为首次从该植物中分离得到,化合物1和6具有显著抑制小鼠巨噬细胞RAW 264.7释放NO的活性。
AIM: To study the chemical constituents from the aerial parts of Lamiophlomis rotata. METHODS: The chemical constituents were isolated and purified by several column chromatographic methods. Their structures were elucidated on the basis of chemical and spectral analysis. RESULTS: Twelve compounds were isolated from the 95% ethanol extract of the aerial parts of L.rotata. Their structures were identified as luteolin (1), luteolin 7-O-β-D-glucopyranoside (2),apigenin (3), apigenin 7-O-β-D-glucopyranoside (4), apigenin 7-O-(6″-(E)-p-coumaroyl)-β-D-galactopyranoside (5), tricin (6), acacetin (7), genkwanin (8), lamiophlomiol A (9), lamiophlomiol B (10), shanzhiside methyl ester(11)and syringic acid (12), respectively. CONCLUSION: Compounds 5-8 and 12 have been isolated from this plant for the first time. Compounds 1 and 6 showed potent inhibitory effects on the production of NO in RAW 264.7 cells.
