摘要
从台湾Cuscuta japonica var. formosana的地上部分分离到一种新的酰胺衍生物cuscujaponamide(1),并分离到山奈酚(2)、槲皮素(3)、黄芪甲苷(4)、金丝桃苷(5)、(+)-松脂醇(6)、(+)-芝麻素(7)、咖啡酸(8)和对香豆酸(9)等8个已知化合物。其中,菟丝子酰胺(1)、山奈酚(2)、金丝桃苷(5)和(+)-松脂醇(6)对lps诱导的NO生成具有较强的抑制作用,IC50值分别为16.03±1.46、18.52±1.70、18.17±1.64和15.90±2.04 μM。此外,化合物1、2、3和5也具有较强的DPPH自由基清除能力,IC50值分别为17.29±1.63 μM、19.02±2.14 μM、15.62±1.42 μM和13.25±1.45 μM。
Anti-Inflammatory and Antioxidant Constituents from Cuscuta japonica var. formosana
A new amide derivative, cuscujaponamide (1), has been isolated from the aerial parts of Cuscuta japonica var. formosana, together with eight known compounds, kaempferol (2), quercetin (3), astragalin (4), hyperoside (5), (+)-pinoresinol (6), (+)-sesamin (7), caffeic acid (8), and p-coumaric acid (9). The structure of the new compound 1 was determined through spectroscopic and MS analyses. Among the isolates, cuscujaponamide (1), kaempferol (2), hyperoside (5), and (+)-pinoresinol (6) showed potent inhibition with IC50 values of 16.03 ±1.46, 18.52 ± 1.70, 18.17 ± 1.64, and 15.90 ± 2.04 μM, respectively, against LPS-induced NO generation. In addition, compounds 1, 2, 3, and 5 also showed potent DPPH radicals scavenging activities with IC50 values of 17.29 ± 1.63, 19.02 ± 2.14, 15.62 ±1.42, and 13.25 ±1.45 μM, respectively.
