A new phenylethanoid glycoside, named taraffinisoside A (1), together with five known glycosides were isolated from the stems and leaves of Tarphochlamys affinis. The structure of taraffinisoside A was identified on the basis of detailed spectral analysis. Compounds 1-4 and 6 showed potent antioxidant activities with IC50 values of 10.36, 19.73, 43.95, 15.30 and 46.04 μM by 1,1-diphenyl-2-picryhydrazyl radical-scavenging assay. Compounds 1, 2 and 4 showed anti-HBV activities, with IC50 values of 0.50, 0.72 and 0.26 mM for HBsAg and 0.93, 0.42 and 0.07 mM for HBeAg, respectively.
从短梗南蛇藤的茎和叶中分离得到了一种新的苯乙醇苷类化合物,命名为塔拉菲尼苷 A(1),此外还分离得到了另外 5 种已知的糖苷类化合物。基于详细的光谱分析确定了塔拉菲尼苷 A 的结构。化合物 1-4 和 6 通过 1,1-二苯基-2-苦基肼基自由基清除试验显示出较强的抗氧化活性,其 IC50 值分别为 10.36、19.73、43.95、15.30 和 46.04 μM。化合物 1、2 和 4 对乙型肝炎病毒具有抗 HBV 活性,其对 HBsAg 的 IC50 值分别为 0.50、0.72 和 0.26 mM,对 HBeAg 的 IC50 值分别为 0.93、0.42 和 0.07 mM。
